	@mansect description
	@command{@gpgname} is the OpenPGP part of the GNU Privacy Guard (GnuPG). It
	is a tool to provide digital encryption and signing services using the
	OpenPGP standard. @command{@gpgname} features complete key management and
	all bells and whistles you can expect from a decent OpenPGP
	implementation.

	In contrast to the standalone command gpg from GnuPG 1.x, which is
	might be better suited for server and embedded platforms, the 2.x
	version is commonly installed under the name @command{gpg2} and
	targeted to the desktop as it requires several other modules to be
	installed.

	@manpause
	The old 1.x version will be kept maintained and it is possible to
	install both versions on the same system. Documentation for the old
	GnuPG 1.x command is available as a man page and at
	@inforef{Top,GnuPG 1,gpg}.

	@node Operational GPG Commands
	@subsection Commands to select the type of operation


	@table @gnupgtabopt

	@item --sign
	@itemx -s
	@opindex sign
	Make a signature. This command may be combined with @option{--encrypt}
	(for a signed and encrypted message), @option{--symmetric} (for a
	signed and symmetrically encrypted message), or @option{--encrypt} and
	@option{--symmetric} together (for a signed message that may be
	decrypted via a secret key or a passphrase). The key to be used for
	signing is chosen by default or can be set with the
	@option{--local-user} and @option{--default-key} options.

	@item --clearsign
	@opindex clearsign
	Make a clear text signature. The content in a clear text signature is
	readable without any special software. OpenPGP software is only needed
	to verify the signature. Clear text signatures may modify end-of-line
	whitespace for platform independence and are not intended to be
	reversible. The key to be used for signing is chosen by default or
	can be set with the @option{--local-user} and @option{--default-key}
	options.


	@item --detach-sign
	@itemx -b
	@opindex detach-sign
	Make a detached signature.

	@item --encrypt
	@itemx -e
	@opindex encrypt
	Encrypt data. This option may be combined with @option{--sign} (for a
	signed and encrypted message), @option{--symmetric} (for a message that
	may be decrypted via a secret key or a passphrase), or @option{--sign}
	and @option{--symmetric} together (for a signed message that may be
	decrypted via a secret key or a passphrase).

	@item --symmetric
	@itemx -c
	@opindex symmetric
	Encrypt with a symmetric cipher using a passphrase. The default
	symmetric cipher used is @value{GPGSYMENCALGO}, but may be chosen with the
	@option{--cipher-algo} option. This option may be combined with
	@option{--sign} (for a signed and symmetrically encrypted message),
	@option{--encrypt} (for a message that may be decrypted via a secret key
	or a passphrase), or @option{--sign} and @option{--encrypt} together
	(for a signed message that may be decrypted via a secret key or a
	passphrase).

	@item --store
	@opindex store
	Store only (make a simple RFC1991 literal data packet).

	@item --decrypt
	@itemx -d
	@opindex decrypt
	Decrypt the file given on the command line (or STDIN if no file
	is specified) and write it to STDOUT (or the file specified with
	@option{--output}). If the decrypted file is signed, the signature is also
	verified. This command differs from the default operation, as it never
	writes to the filename which is included in the file and it rejects
	files which don't begin with an encrypted message.

	@item --verify
	@opindex verify
	Assume that the first argument is a signed file and verify it without
	generating any output. With no arguments, the signature packet is
	read from STDIN. If only a one argument is given, it is expected to
	be a complete signature.

	With more than 1 argument, the first should be a detached signature
	and the remaining files ake up the the signed data. To read the signed
	data from STDIN, use @samp{-} as the second filename. For security
	reasons a detached signature cannot read the signed material from
	STDIN without denoting it in the above way.

	Note: If the option @option{--batch} is not used, @command{@gpgname}
	may assume that a single argument is a file with a detached signature
	and it will try to find a matching data file by stripping certain
	suffixes. Using this historical feature to verify a detached
	signature is strongly discouraged; always specify the data file too.

	Note: When verifying a cleartext signature, @command{gpg} verifies
	only what makes up the cleartext signed data and not any extra data
	outside of the cleartext signature or header lines following directly
	the dash marker line. The option @code{--output} may be used to write
	out the actual signed data; but there are other pitfalls with this
	format as well. It is suggested to avoid cleartext signatures in
	favor of detached signatures.

	@item --multifile
	@opindex multifile
	This modifies certain other commands to accept multiple files for
	processing on the command line or read from STDIN with each filename on
	a separate line. This allows for many files to be processed at
	once. @option{--multifile} may currently be used along with
	@option{--verify}, @option{--encrypt}, and @option{--decrypt}. Note that
	@option{--multifile --verify} may not be used with detached signatures.

	@item --verify-files
	@opindex verify-files
	Identical to @option{--multifile --verify}.

	@item --encrypt-files
	@opindex encrypt-files
	Identical to @option{--multifile --encrypt}.

	@item --decrypt-files
	@opindex decrypt-files
	Identical to @option{--multifile --decrypt}.

	@item --list-keys
	@itemx -k
	@itemx --list-public-keys
	@opindex list-keys
	List all keys from the public keyrings, or just the keys given on the
	command line.

	Avoid using the output of this command in scripts or other programs as
	it is likely to change as GnuPG changes. See @option{--with-colons} for a
	machine-parseable key listing command that is appropriate for use in
	scripts and other programs.

	@item --list-secret-keys
	@itemx -K
	@opindex list-secret-keys
	List all keys from the secret keyrings, or just the ones given on the
	command line. A @code{#} after the letters @code{sec} means that the
	secret key is not usable (for example, if it was created via
	@option{--export-secret-subkeys}).

	@item --list-sigs
	@opindex list-sigs
	Same as @option{--list-keys}, but the signatures are listed too.
	This command has the same effect as
	using @option{--list-keys} with @option{--with-sig-list}.

	For each signature listed, there are several flags in between the "sig"
	tag and keyid. These flags give additional information about each
	signature. From left to right, they are the numbers 1-3 for certificate
	check level (see @option{--ask-cert-level}), "L" for a local or
	non-exportable signature (see @option{--lsign-key}), "R" for a
	nonRevocable signature (see the @option{--edit-key} command "nrsign"),
	"P" for a signature that contains a policy URL (see
	@option{--cert-policy-url}), "N" for a signature that contains a
	notation (see @option{--cert-notation}), "X" for an eXpired signature
	(see @option{--ask-cert-expire}), and the numbers 1-9 or "T" for 10 and
	above to indicate trust signature levels (see the @option{--edit-key}
	command "tsign").

	@item --check-sigs
	@opindex check-sigs
	Same as @option{--list-sigs}, but the signatures are verified. Note
	that for performance reasons the revocation status of a signing key is
	not shown.
	This command has the same effect as
	using @option{--list-keys} with @option{--with-sig-check}.

	The status of the verification is indicated by a flag directly following
	the "sig" tag (and thus before the flags described above for
	@option{--list-sigs}). A "!" indicates that the signature has been
	successfully verified, a "-" denotes a bad signature and a "%" is used
	if an error occurred while checking the signature (e.g. a non supported
	algorithm).

	@item --locate-keys
	@opindex locate-keys
	Locate the keys given as arguments. This command basically uses the
	same algorithm as used when locating keys for encryption or signing and
	may thus be used to see what keys @command{@gpgname} might use. In
	particular external methods as defined by @option{--auto-key-locate} may
	be used to locate a key. Only public keys are listed.

	@item --fingerprint
	@opindex fingerprint
	List all keys (or the specified ones) along with their
	fingerprints. This is the same output as @option{--list-keys} but with
	the additional output of a line with the fingerprint. May also be
	combined with @option{--list-sigs} or @option{--check-sigs}. If this
	command is given twice, the fingerprints of all secondary keys are
	listed too.

	@item --list-packets
	@opindex list-packets
	List only the sequence of packets. This is mainly useful for
	debugging. When used with option @option{--verbose} the actual MPI
	values are dumped and not only their lengths.


	@item --card-edit
	@opindex card-edit
	Present a menu to work with a smartcard. The subcommand "help" provides
	an overview on available commands. For a detailed description, please
	see the Card HOWTO at
	https://gnupg.org/documentation/howtos.html#GnuPG-cardHOWTO .

	@item --card-status
	@opindex card-status
	Show the content of the smart card.

	@item --change-pin
	@opindex change-pin
	Present a menu to allow changing the PIN of a smartcard. This
	functionality is also available as the subcommand "passwd" with the
	@option{--card-edit} command.

	@item --delete-keys @code{name}
	@itemx --delete-keys @code{name}
	Remove key from the public keyring. In batch mode either @option{--yes} is
	required or the key must be specified by fingerprint. This is a
	safeguard against accidental deletion of multiple keys.

	@item --delete-secret-keys @code{name}
	@opindex delete-secret-keys
	Remove key from the secret keyring. In batch mode the key
	must be specified by fingerprint.

	@item --delete-secret-and-public-key @code{name}
	@opindex delete-secret-and-public-key
	Same as @option{--delete-key}, but if a secret key exists, it will be
	removed first. In batch mode the key must be specified by fingerprint.

	@item --export
	@opindex export
	Either export all keys from all keyrings (default keyrings and those
	registered via option @option{--keyring}), or if at least one name is given,
	those of the given name. The exported keys are written to STDOUT or to the
	file given with option @option{--output}. Use together with
	@option{--armor} to mail those keys.

	@item --send-keys @code{key IDs}
	@opindex send-keys
	Similar to @option{--export} but sends the keys to a keyserver.
	Fingerprints may be used instead of key IDs. Option @option{--keyserver}
	must be used to give the name of this keyserver. Don't send your
	complete keyring to a keyserver --- select only those keys which are new
	or changed by you. If no key IDs are given, @command{gpg} does nothing.

	@item --export-secret-keys
	@itemx --export-secret-subkeys
	@opindex export-secret-keys
	@opindex export-secret-subkeys
	Same as @option{--export}, but exports the secret keys instead. The
	exported keys are written to STDOUT or to the file given with option
	@option{--output}. This command is often used along with the option
	@option{--armor} to allow easy printing of the key for paper backup;
	however the external tool @command{paperkey} does a better job for
	creating backups on paper. Note that exporting a secret key can be a
	security risk if the exported keys are send over an insecure channel.

	The second form of the command has the special property to render the
	secret part of the primary key useless; this is a GNU extension to
	OpenPGP and other implementations can not be expected to successfully
	import such a key. Its intended use is to generated a full key with
	an additional signing subkey on a dedicated machine and then using
	this command to export the key without the primary key to the main
	machine.

	GnuPG may ask you to enter the passphrase for the key. This is
	required because the internal protection method of the secret key is
	different from the one specified by the OpenPGP protocol.

	@item --import
	@itemx --fast-import
	@opindex import
	Import/merge keys. This adds the given keys to the
	keyring. The fast version is currently just a synonym.

	There are a few other options which control how this command works.
	Most notable here is the @option{--import-options merge-only} option
	which does not insert new keys but does only the merging of new
	signatures, user-IDs and subkeys.

	@item --recv-keys @code{key IDs}
	@opindex recv-keys
	Import the keys with the given key IDs from a keyserver. Option
	@option{--keyserver} must be used to give the name of this keyserver.

	@item --refresh-keys
	@opindex refresh-keys
	Request updates from a keyserver for keys that already exist on the
	local keyring. This is useful for updating a key with the latest
	signatures, user IDs, etc. Calling this with no arguments will refresh
	the entire keyring. Option @option{--keyserver} must be used to give the
	name of the keyserver for all keys that do not have preferred keyservers
	set (see @option{--keyserver-options honor-keyserver-url}).

	@item --search-keys @code{names}
	@opindex search-keys
	Search the keyserver for the given names. Multiple names given here will
	be joined together to create the search string for the keyserver.
	Option @option{--keyserver} must be used to give the name of this
	keyserver. Keyservers that support different search methods allow using
	the syntax specified in "How to specify a user ID" below. Note that
	different keyserver types support different search methods. Currently
	only LDAP supports them all.

	@item --fetch-keys @code{URIs}
	@opindex fetch-keys
	Retrieve keys located at the specified URIs. Note that different
	installations of GnuPG may support different protocols (HTTP, FTP,
	LDAP, etc.)

	@item --update-trustdb
	@opindex update-trustdb
	Do trust database maintenance. This command iterates over all keys and
	builds the Web of Trust. This is an interactive command because it may
	have to ask for the "ownertrust" values for keys. The user has to give
	an estimation of how far she trusts the owner of the displayed key to
	correctly certify (sign) other keys. GnuPG only asks for the ownertrust
	value if it has not yet been assigned to a key. Using the
	@option{--edit-key} menu, the assigned value can be changed at any time.

	@item --check-trustdb
	@opindex check-trustdb
	Do trust database maintenance without user interaction. From time to
	time the trust database must be updated so that expired keys or
	signatures and the resulting changes in the Web of Trust can be
	tracked. Normally, GnuPG will calculate when this is required and do it
	automatically unless @option{--no-auto-check-trustdb} is set. This
	command can be used to force a trust database check at any time. The
	processing is identical to that of @option{--update-trustdb} but it
	skips keys with a not yet defined "ownertrust".

	For use with cron jobs, this command can be used together with
	@option{--batch} in which case the trust database check is done only if
	a check is needed. To force a run even in batch mode add the option
	@option{--yes}.

	@anchor{option --export-ownertrust}
	@item --export-ownertrust
	@opindex export-ownertrust
	Send the ownertrust values to STDOUT. This is useful for backup purposes
	as these values are the only ones which can't be re-created from a
	corrupted trustdb. Example:
	@c man:.RS
	@example
	@gpgname{} --export-ownertrust > otrust.txt
	@end example
	@c man:.RE


	@item --import-ownertrust
	@opindex import-ownertrust
	Update the trustdb with the ownertrust values stored in @code{files} (or
	STDIN if not given); existing values will be overwritten. In case of a
	severely damaged trustdb and if you have a recent backup of the
	ownertrust values (e.g. in the file @file{otrust.txt}, you may re-create
	the trustdb using these commands:
	@c man:.RS
	@example
	cd ~/.gnupg
	rm trustdb.gpg
	@gpgname{} --import-ownertrust < otrust.txt
	@end example
	@c man:.RE


	@item --rebuild-keydb-caches
	@opindex rebuild-keydb-caches
	When updating from version 1.0.6 to 1.0.7 this command should be used
	to create signature caches in the keyring. It might be handy in other
	situations too.

	@item --print-md @code{algo}
	@itemx --print-mds
	@opindex print-md
	Print message digest of algorithm ALGO for all given files or STDIN.
	With the second form (or a deprecated "*" as algo) digests for all
	available algorithms are printed.

	@item --gen-random @code{0\|1\|2} @code{count}
	@opindex gen-random
	Emit @var{count} random bytes of the given quality level 0, 1 or 2. If
	@var{count} is not given or zero, an endless sequence of random bytes
	will be emitted. If used with @option{--armor} the output will be
	base64 encoded. PLEASE, don't use this command unless you know what
	you are doing; it may remove precious entropy from the system!

	@item --gen-prime @code{mode} @code{bits}
	@opindex gen-prime
	Use the source, Luke :-). The output format is still subject to change.


	@item --enarmor
	@item --dearmor
	@opindex enarmor
	@opindex dearmor
	Pack or unpack an arbitrary input into/from an OpenPGP ASCII armor.
	This is a GnuPG extension to OpenPGP and in general not very useful.


	@c @item --server
	@c @opindex server
	@c Run gpg in server mode. This feature is not yet ready for use and
	@c thus not documented.

	@end table


	@c *******************************************
	@c ***** KEY MANGEMENT COMMANDS ********
	@c *******************************************
	@node OpenPGP Key Management
	@subsection How to manage your keys

	This section explains the main commands for key management

	@table @gnupgtabopt

	@item --quick-gen-key @code{user-id}
	@opindex quick-gen-key
	This is a simple command to generate a standard key with one user id.
	In contrast to @option{--gen-key} the key is generated directly
	without the need to answer a bunch of prompts. Unless the option
	@option{--yes} is given, the key creation will be canceled if the
	given user id already exists in the key ring.

	If invoked directly on the console without any special options an
	answer to a ``Continue?'' style confirmation prompt is required. In
	case the user id already exists in the key ring a second prompt to
	force the creation of the key will show up.

	If this command is used with @option{--batch},
	@option{--pinentry-mode} has been set to @code{loopback}, and one of
	the passphrase options (@option{--passphrase},
	@option{--passphrase-fd}, or @option{passphrase-file}) is used, the
	supplied passphrase is used for the new key and the agent does not ask
	for it. To create a key without any protection @code{--passphrase ''}
	may be used.

	@item --gen-key
	@opindex gen-key
	Generate a new key pair using the current default parameters. This is
	the standard command to create a new key.

	@item --full-gen-key
	@opindex gen-key
	Generate a new key pair with dialogs for all options. This is an
	extended version of @option{--gen-key}.

	There is also a feature which allows you to create keys in batch
	mode. See the the manual section ``Unattended key generation'' on how
	to use this.

	@item --gen-revoke @code{name}
	@opindex gen-revoke
	Generate a revocation certificate for the complete key. To revoke
	a subkey or a signature, use the @option{--edit} command.

	@item --desig-revoke @code{name}
	@opindex desig-revoke
	Generate a designated revocation certificate for a key. This allows a
	user (with the permission of the keyholder) to revoke someone else's
	key.


	@item --edit-key
	@opindex edit-key
	Present a menu which enables you to do most of the key management
	related tasks. It expects the specification of a key on the command
	line.

	@c ****** Begin Edit-key Options ********
	@table @asis

	@item uid @code{n}
	@opindex keyedit:uid
	Toggle selection of user ID or photographic user ID with index @code{n}.
	Use @code{*} to select all and @code{0} to deselect all.

	@item key @code{n}
	@opindex keyedit:key
	Toggle selection of subkey with index @code{n}.
	Use @code{*} to select all and @code{0} to deselect all.

	@item sign
	@opindex keyedit:sign
	Make a signature on key of user @code{name} If the key is not yet
	signed by the default user (or the users given with -u), the program
	displays the information of the key again, together with its
	fingerprint and asks whether it should be signed. This question is
	repeated for all users specified with
	-u.

	@item lsign
	@opindex keyedit:lsign
	Same as "sign" but the signature is marked as non-exportable and will
	therefore never be used by others. This may be used to make keys
	valid only in the local environment.

	@item nrsign
	@opindex keyedit:nrsign
	Same as "sign" but the signature is marked as non-revocable and can
	therefore never be revoked.

	@item tsign
	@opindex keyedit:tsign
	Make a trust signature. This is a signature that combines the notions
	of certification (like a regular signature), and trust (like the
	"trust" command). It is generally only useful in distinct communities
	or groups.
	@end table

	@c man:.RS
	Note that "l" (for local / non-exportable), "nr" (for non-revocable,
	and "t" (for trust) may be freely mixed and prefixed to "sign" to
	create a signature of any type desired.
	@c man:.RE

	@table @asis

	@item delsig
	@opindex keyedit:delsig
	Delete a signature. Note that it is not possible to retract a signature,
	once it has been send to the public (i.e. to a keyserver). In that case
	you better use @code{revsig}.

	@item revsig
	@opindex keyedit:revsig
	Revoke a signature. For every signature which has been generated by
	one of the secret keys, GnuPG asks whether a revocation certificate
	should be generated.

	@item check
	@opindex keyedit:check
	Check the signatures on all selected user IDs. With the extra
	option @code{selfsig} only self-signatures are shown.

	@item adduid
	@opindex keyedit:adduid
	Create an additional user ID.

	@item addphoto
	@opindex keyedit:addphoto
	Create a photographic user ID. This will prompt for a JPEG file that
	will be embedded into the user ID. Note that a very large JPEG will make
	for a very large key. Also note that some programs will display your
	JPEG unchanged (GnuPG), and some programs will scale it to fit in a
	dialog box (PGP).

	@item showphoto
	@opindex keyedit:showphoto
	Display the selected photographic user ID.

	@item deluid
	@opindex keyedit:deluid
	Delete a user ID or photographic user ID. Note that it is not
	possible to retract a user id, once it has been send to the public
	(i.e. to a keyserver). In that case you better use @code{revuid}.

	@item revuid
	@opindex keyedit:revuid
	Revoke a user ID or photographic user ID.

	@item primary
	@opindex keyedit:primary
	Flag the current user id as the primary one, removes the primary user
	id flag from all other user ids and sets the timestamp of all affected
	self-signatures one second ahead. Note that setting a photo user ID
	as primary makes it primary over other photo user IDs, and setting a
	regular user ID as primary makes it primary over other regular user
	IDs.

	@item keyserver
	@opindex keyedit:keyserver
	Set a preferred keyserver for the specified user ID(s). This allows
	other users to know where you prefer they get your key from. See
	@option{--keyserver-options honor-keyserver-url} for more on how this
	works. Setting a value of "none" removes an existing preferred
	keyserver.

	@item notation
	@opindex keyedit:notation
	Set a name=value notation for the specified user ID(s). See
	@option{--cert-notation} for more on how this works. Setting a value of
	"none" removes all notations, setting a notation prefixed with a minus
	sign (-) removes that notation, and setting a notation name (without the
	=value) prefixed with a minus sign removes all notations with that name.

	@item pref
	@opindex keyedit:pref
	List preferences from the selected user ID. This shows the actual
	preferences, without including any implied preferences.

	@item showpref
	@opindex keyedit:showpref
	More verbose preferences listing for the selected user ID. This shows
	the preferences in effect by including the implied preferences of 3DES
	(cipher), SHA-1 (digest), and Uncompressed (compression) if they are
	not already included in the preference list. In addition, the
	preferred keyserver and signature notations (if any) are shown.

	@item setpref @code{string}
	@opindex keyedit:setpref
	Set the list of user ID preferences to @code{string} for all (or just
	the selected) user IDs. Calling setpref with no arguments sets the
	preference list to the default (either built-in or set via
	@option{--default-preference-list}), and calling setpref with "none"
	as the argument sets an empty preference list. Use @command{@gpgname
	--version} to get a list of available algorithms. Note that while you
	can change the preferences on an attribute user ID (aka "photo ID"),
	GnuPG does not select keys via attribute user IDs so these preferences
	will not be used by GnuPG.

	When setting preferences, you should list the algorithms in the order
	which you'd like to see them used by someone else when encrypting a
	message to your key. If you don't include 3DES, it will be
	automatically added at the end. Note that there are many factors that
	go into choosing an algorithm (for example, your key may not be the
	only recipient), and so the remote OpenPGP application being used to
	send to you may or may not follow your exact chosen order for a given
	message. It will, however, only choose an algorithm that is present
	on the preference list of every recipient key. See also the
	INTEROPERABILITY WITH OTHER OPENPGP PROGRAMS section below.

	@item addkey
	@opindex keyedit:addkey
	Add a subkey to this key.

	@item addcardkey
	@opindex keyedit:addcardkey
	Generate a subkey on a card and add it to this key.

	@item keytocard
	@opindex keyedit:keytocard
	Transfer the selected secret subkey (or the primary key if no subkey
	has been selected) to a smartcard. The secret key in the keyring will
	be replaced by a stub if the key could be stored successfully on the
	card and you use the save command later. Only certain key types may be
	transferred to the card. A sub menu allows you to select on what card
	to store the key. Note that it is not possible to get that key back
	from the card - if the card gets broken your secret key will be lost
	unless you have a backup somewhere.

	@item bkuptocard @code{file}
	@opindex keyedit:bkuptocard
	Restore the given file to a card. This command may be used to restore a
	backup key (as generated during card initialization) to a new card. In
	almost all cases this will be the encryption key. You should use this
	command only with the corresponding public key and make sure that the
	file given as argument is indeed the backup to restore. You should then
	select 2 to restore as encryption key. You will first be asked to enter
	the passphrase of the backup key and then for the Admin PIN of the card.

	@item delkey
	@opindex keyedit:delkey
	Remove a subkey (secondary key). Note that it is not possible to retract
	a subkey, once it has been send to the public (i.e. to a keyserver). In
	that case you better use @code{revkey}.

	@item revkey
	@opindex keyedit:revkey
	Revoke a subkey.

	@item expire
	@opindex keyedit:expire
	Change the key or subkey expiration time. If a subkey is selected, the
	expiration time of this subkey will be changed. With no selection, the
	key expiration of the primary key is changed.

	@item trust
	@opindex keyedit:trust
	Change the owner trust value for the key. This updates the trust-db
	immediately and no save is required.

	@item disable
	@itemx enable
	@opindex keyedit:disable
	@opindex keyedit:enable
	Disable or enable an entire key. A disabled key can not normally be
	used for encryption.

	@item addrevoker
	@opindex keyedit:addrevoker
	Add a designated revoker to the key. This takes one optional argument:
	"sensitive". If a designated revoker is marked as sensitive, it will
	not be exported by default (see export-options).

	@item passwd
	@opindex keyedit:passwd
	Change the passphrase of the secret key.

	@item toggle
	@opindex keyedit:toggle
	This is dummy command which exists only for backward compatibility.

	@item clean
	@opindex keyedit:clean
	Compact (by removing all signatures except the selfsig) any user ID
	that is no longer usable (e.g. revoked, or expired). Then, remove any
	signatures that are not usable by the trust calculations.
	Specifically, this removes any signature that does not validate, any
	signature that is superseded by a later signature, revoked signatures,
	and signatures issued by keys that are not present on the keyring.

	@item minimize
	@opindex keyedit:minimize
	Make the key as small as possible. This removes all signatures from
	each user ID except for the most recent self-signature.

	@item cross-certify
	@opindex keyedit:cross-certify
	Add cross-certification signatures to signing subkeys that may not
	currently have them. Cross-certification signatures protect against a
	subtle attack against signing subkeys. See
	@option{--require-cross-certification}. All new keys generated have
	this signature by default, so this option is only useful to bring
	older keys up to date.

	@item save
	@opindex keyedit:save
	Save all changes to the key rings and quit.

	@item quit
	@opindex keyedit:quit
	Quit the program without updating the
	key rings.
	@end table

	@c ****** End Edit-key Options ********

	@item --sign-key @code{name}
	@opindex sign-key
	Signs a public key with your secret key. This is a shortcut version of
	the subcommand "sign" from @option{--edit}.

	@item --lsign-key @code{name}
	@opindex lsign-key
	Signs a public key with your secret key but marks it as
	non-exportable. This is a shortcut version of the subcommand "lsign"
	from @option{--edit-key}.

	@item --quick-sign-key @code{fpr} [@code{names}]
	@itemx --quick-lsign-key @code{fpr} [@code{names}]
	@opindex quick-sign-key
	@opindex quick-lsign-key
	Directly sign a key from the passphrase without any further user
	interaction. The @code{fpr} must be the verified primary fingerprint
	of a key in the local keyring. If no @code{names} are given, all
	useful user ids are signed; with given [@code{names}] only useful user
	ids matching one of theses names are signed. The command
	@option{--quick-lsign-key} marks the signatures as non-exportable. If
	such a non-exportable signature already exists the
	@option{--quick-sign-key} turns it into a exportable signature.

	This command uses reasonable defaults and thus does not provide the
	full flexibility of the "sign" subcommand from @option{--edit-key}.
	Its intended use is to help unattended key signing by utilizing a list
	of verified fingerprints.

	@item --quick-adduid @var{user-id} @var{new-user-id}
	@opindex quick-adduid
	This command adds a new user id to an existing key. In contrast to
	the interactive sub-command @code{adduid} of @option{--edit-key} the
	@var{new-user-id} is added verbatim with only leading and trailing
	white space removed, it is expected to be UTF-8 encoded, and no checks
	on its form are applied.

	@item --passwd @var{user_id}
	@opindex passwd
	Change the passphrase of the secret key belonging to the certificate
	specified as @var{user_id}. This is a shortcut for the sub-command
	@code{passwd} of the edit key menu.

	not generally useful as the command will execute automatically with
	every execution of gpg.

	Please remember that option parsing stops as soon as a non-option is

	@node GPG Configuration Options
	@subsection How to change the configuration

	These options are used to change the configuration and are usually found
	in the option file.

	@table @gnupgtabopt

	@item --default-key @var{name}
	@opindex default-key
	Use @var{name} as the default key to sign with. If this option is not
	used, the default key is the first key found in the secret keyring.
	Note that @option{-u} or @option{--local-user} overrides this option.

	@item --default-recipient @var{name}
	@opindex default-recipient
	Use @var{name} as default recipient if option @option{--recipient} is
	not used and don't ask if this is a valid one. @var{name} must be
	non-empty.

	@item --default-recipient-self
	@opindex default-recipient-self
	Use the default key as default recipient if option @option{--recipient} is not
	used and don't ask if this is a valid one. The default key is the first
	one from the secret keyring or the one set with @option{--default-key}.

	@item --no-default-recipient
	@opindex no-default-recipient
	Reset @option{--default-recipient} and @option{--default-recipient-self}.

	@item -v, --verbose
	@opindex verbose
	Give more information during processing. If used
	twice, the input data is listed in detail.

	@item --no-verbose
	@opindex no-verbose
	Reset verbose level to 0.

	@item -q, --quiet
	@opindex quiet
	Try to be as quiet as possible.

	@item --batch
	@itemx --no-batch
	@opindex batch
	@opindex no-batch
	Use batch mode. Never ask, do not allow interactive commands.
	@option{--no-batch} disables this option. Note that even with a
	filename given on the command line, gpg might still need to read from
	STDIN (in particular if gpg figures that the input is a
	detached signature and no data file has been specified). Thus if you
	do not want to feed data via STDIN, you should connect STDIN to
	@file{/dev/null}.

	@item --no-tty
	@opindex no-tty
	Make sure that the TTY (terminal) is never used for any output.
	This option is needed in some cases because GnuPG sometimes prints
	warnings to the TTY even if @option{--batch} is used.

	@item --yes
	@opindex yes
	Assume "yes" on most questions.

	@item --no
	@opindex no
	Assume "no" on most questions.


	@item --list-options @code{parameters}
	@opindex list-options
	This is a space or comma delimited string that gives options used when
	listing keys and signatures (that is, @option{--list-keys},
	@option{--list-sigs}, @option{--list-public-keys},
	@option{--list-secret-keys}, and the @option{--edit-key} functions).
	Options can be prepended with a @option{no-} (after the two dashes) to
	give the opposite meaning. The options are:

	@table @asis

	@item show-photos
	@opindex list-options:show-photos
	Causes @option{--list-keys}, @option{--list-sigs},
	@option{--list-public-keys}, and @option{--list-secret-keys} to
	display any photo IDs attached to the key. Defaults to no. See also
	@option{--photo-viewer}. Does not work with @option{--with-colons}:
	see @option{--attribute-fd} for the appropriate way to get photo data
	for scripts and other frontends.

	@item show-usage
	@opindex list-options:show-usage
	Show usage information for keys and subkeys in the standard key
	listing. This is a list of letters indicating the allowed usage for a
	key (@code{E}=encryption, @code{S}=signing, @code{C}=certification,
	@code{A}=authentication). Defaults to no.

	@item show-policy-urls
	@opindex list-options:show-policy-urls
	Show policy URLs in the @option{--list-sigs} or @option{--check-sigs}
	listings. Defaults to no.

	@item show-notations
	@itemx show-std-notations
	@itemx show-user-notations
	@opindex list-options:show-notations
	@opindex list-options:show-std-notations
	@opindex list-options:show-user-notations
	Show all, IETF standard, or user-defined signature notations in the
	@option{--list-sigs} or @option{--check-sigs} listings. Defaults to no.

	@item show-keyserver-urls
	@opindex list-options:show-keyserver-urls
	Show any preferred keyserver URL in the @option{--list-sigs} or
	@option{--check-sigs} listings. Defaults to no.

	@item show-uid-validity
	@opindex list-options:show-uid-validity
	Display the calculated validity of user IDs during key listings.
	Defaults to no.

	@item show-unusable-uids
	@opindex list-options:show-unusable-uids
	Show revoked and expired user IDs in key listings. Defaults to no.

	@item show-unusable-subkeys
	@opindex list-options:show-unusable-subkeys
	Show revoked and expired subkeys in key listings. Defaults to no.

	@item show-keyring
	@opindex list-options:show-keyring
	Display the keyring name at the head of key listings to show which
	keyring a given key resides on. Defaults to no.

	@item show-sig-expire
	@opindex list-options:show-sig-expire
	Show signature expiration dates (if any) during @option{--list-sigs} or
	@option{--check-sigs} listings. Defaults to no.

	@item show-sig-subpackets
	@opindex list-options:show-sig-subpackets
	Include signature subpackets in the key listing. This option can take an
	optional argument list of the subpackets to list. If no argument is
	passed, list all subpackets. Defaults to no. This option is only
	meaningful when using @option{--with-colons} along with
	@option{--list-sigs} or @option{--check-sigs}.

	@end table

	@item --verify-options @code{parameters}
	@opindex verify-options
	This is a space or comma delimited string that gives options used when
	verifying signatures. Options can be prepended with a `no-' to give
	the opposite meaning. The options are:

	@table @asis

	@item show-photos
	@opindex verify-options:show-photos
	Display any photo IDs present on the key that issued the signature.
	Defaults to no. See also @option{--photo-viewer}.

	@item show-policy-urls
	@opindex verify-options:show-policy-urls
	Show policy URLs in the signature being verified. Defaults to no.

	@item show-notations
	@itemx show-std-notations
	@itemx show-user-notations
	@opindex verify-options:show-notations
	@opindex verify-options:show-std-notations
	@opindex verify-options:show-user-notations
	Show all, IETF standard, or user-defined signature notations in the
	signature being verified. Defaults to IETF standard.

	@item show-keyserver-urls
	@opindex verify-options:show-keyserver-urls
	Show any preferred keyserver URL in the signature being verified.
	Defaults to no.

	@item show-uid-validity
	@opindex verify-options:show-uid-validity
	Display the calculated validity of the user IDs on the key that issued
	the signature. Defaults to no.

	@item show-unusable-uids
	@opindex verify-options:show-unusable-uids
	Show revoked and expired user IDs during signature verification.
	Defaults to no.

	@item show-primary-uid-only
	@opindex verify-options:show-primary-uid-only
	Show only the primary user ID during signature verification. That is
	all the AKA lines as well as photo Ids are not shown with the signature
	verification status.

	@item pka-lookups
	@opindex verify-options:pka-lookups
	Enable PKA lookups to verify sender addresses. Note that PKA is based
	on DNS, and so enabling this option may disclose information on when
	and what signatures are verified or to whom data is encrypted. This
	is similar to the "web bug" described for the auto-key-retrieve
	feature.

	@item pka-trust-increase
	@opindex verify-options:pka-trust-increase
	Raise the trust in a signature to full if the signature passes PKA
	validation. This option is only meaningful if pka-lookups is set.
	@end table

	@item --enable-large-rsa
	@itemx --disable-large-rsa
	@opindex enable-large-rsa
	@opindex disable-large-rsa
	With --gen-key and --batch, enable the creation of larger RSA secret
	keys than is generally recommended (up to 8192 bits). These large
	keys are more expensive to use, and their signatures and
	certifications are also larger.

	@item --enable-dsa2
	@itemx --disable-dsa2
	@opindex enable-dsa2
	@opindex disable-dsa2
	Enable hash truncation for all DSA keys even for old DSA Keys up to
	1024 bit. This is also the default with @option{--openpgp}. Note
	that older versions of GnuPG also required this flag to allow the
	generation of DSA larger than 1024 bit.

	@item --photo-viewer @code{string}
	@opindex photo-viewer
	This is the command line that should be run to view a photo ID. "%i"
	will be expanded to a filename containing the photo. "%I" does the
	same, except the file will not be deleted once the viewer exits.
	Other flags are "%k" for the key ID, "%K" for the long key ID, "%f"
	for the key fingerprint, "%t" for the extension of the image type
	(e.g. "jpg"), "%T" for the MIME type of the image (e.g. "image/jpeg"),
	"%v" for the single-character calculated validity of the image being
	viewed (e.g. "f"), "%V" for the calculated validity as a string (e.g.
	"full"), "%U" for a base32 encoded hash of the user ID,
	and "%%" for an actual percent sign. If neither %i or %I are present,
	then the photo will be supplied to the viewer on standard input.

	The default viewer is "xloadimage -fork -quiet -title 'KeyID 0x%k'
	STDIN". Note that if your image viewer program is not secure, then
	executing it from GnuPG does not make it secure.

	@item --exec-path @code{string}
	@opindex exec-path
	Sets a list of directories to search for photo viewers and keyserver
	helpers. If not provided, keyserver helpers use the compiled-in
	default directory, and photo viewers use the $PATH environment
	variable.
	Note, that on W32 system this value is ignored when searching for
	keyserver helpers.

	@item --keyring @code{file}
	@opindex keyring
	Add @code{file} to the current list of keyrings. If @code{file} begins
	with a tilde and a slash, these are replaced by the $HOME directory. If
	the filename does not contain a slash, it is assumed to be in the GnuPG
	home directory ("~/.gnupg" if @option{--homedir} or $GNUPGHOME is not
	used).

	Note that this adds a keyring to the current list. If the intent is to
	use the specified keyring alone, use @option{--keyring} along with
	@option{--no-default-keyring}.

	@item --secret-keyring @code{file}
	@opindex secret-keyring
	This is an obsolete option and ignored. All secret keys are stored in
	the @file{private-keys-v1.d} directory below the GnuPG home directory.

	@item --primary-keyring @code{file}
	@opindex primary-keyring
	Designate @code{file} as the primary public keyring. This means that
	newly imported keys (via @option{--import} or keyserver
	@option{--recv-from}) will go to this keyring.

	@item --trustdb-name @code{file}
	@opindex trustdb-name
	Use @code{file} instead of the default trustdb. If @code{file} begins
	with a tilde and a slash, these are replaced by the $HOME directory. If
	the filename does not contain a slash, it is assumed to be in the GnuPG
	home directory (@file{~/.gnupg} if @option{--homedir} or $GNUPGHOME is
	not used).

	@include opt-homedir.texi


	@item --display-charset @code{name}
	@opindex display-charset
	Set the name of the native character set. This is used to convert
	some informational strings like user IDs to the proper UTF-8 encoding.
	Note that this has nothing to do with the character set of data to be
	encrypted or signed; GnuPG does not recode user-supplied data. If
	this option is not used, the default character set is determined from
	the current locale. A verbosity level of 3 shows the chosen set.
	Valid values for @code{name} are:

	@table @asis

	@item iso-8859-1
	@opindex display-charset:iso-8859-1
	This is the Latin 1 set.

	@item iso-8859-2
	@opindex display-charset:iso-8859-2
	The Latin 2 set.

	@item iso-8859-15
	@opindex display-charset:iso-8859-15
	This is currently an alias for
	the Latin 1 set.

	@item koi8-r
	@opindex display-charset:koi8-r
	The usual Russian set (rfc1489).

	@item utf-8
	@opindex display-charset:utf-8
	Bypass all translations and assume
	that the OS uses native UTF-8 encoding.
	@end table

	@item --utf8-strings
	@itemx --no-utf8-strings
	@opindex utf8-strings
	Assume that command line arguments are given as UTF8 strings. The
	default (@option{--no-utf8-strings}) is to assume that arguments are
	encoded in the character set as specified by
	@option{--display-charset}. These options affect all following
	arguments. Both options may be used multiple times.

	@anchor{gpg-option --options}
	@item --options @code{file}
	@opindex options
	Read options from @code{file} and do not try to read them from the
	default options file in the homedir (see @option{--homedir}). This
	option is ignored if used in an options file.

	@item --no-options
	@opindex no-options
	Shortcut for @option{--options /dev/null}. This option is detected
	before an attempt to open an option file. Using this option will also
	prevent the creation of a @file{~/.gnupg} homedir.

	@item -z @code{n}
	@itemx --compress-level @code{n}
	@itemx --bzip2-compress-level @code{n}
	@opindex compress-level
	@opindex bzip2-compress-level
	Set compression level to @code{n} for the ZIP and ZLIB compression
	algorithms. The default is to use the default compression level of zlib
	(normally 6). @option{--bzip2-compress-level} sets the compression level
	for the BZIP2 compression algorithm (defaulting to 6 as well). This is a
	different option from @option{--compress-level} since BZIP2 uses a
	significant amount of memory for each additional compression level.
	@option{-z} sets both. A value of 0 for @code{n} disables compression.

	@item --bzip2-decompress-lowmem
	@opindex bzip2-decompress-lowmem
	Use a different decompression method for BZIP2 compressed files. This
	alternate method uses a bit more than half the memory, but also runs
	at half the speed. This is useful under extreme low memory
	circumstances when the file was originally compressed at a high
	@option{--bzip2-compress-level}.


	@item --mangle-dos-filenames
	@itemx --no-mangle-dos-filenames
	@opindex mangle-dos-filenames
	@opindex no-mangle-dos-filenames
	Older version of Windows cannot handle filenames with more than one
	dot. @option{--mangle-dos-filenames} causes GnuPG to replace (rather
	than add to) the extension of an output filename to avoid this
	problem. This option is off by default and has no effect on non-Windows
	platforms.

	@item --ask-cert-level
	@itemx --no-ask-cert-level
	@opindex ask-cert-level
	When making a key signature, prompt for a certification level. If this
	option is not specified, the certification level used is set via
	@option{--default-cert-level}. See @option{--default-cert-level} for
	information on the specific levels and how they are
	used. @option{--no-ask-cert-level} disables this option. This option
	defaults to no.

	@item --default-cert-level @code{n}
	@opindex default-cert-level
	The default to use for the check level when signing a key.

	0 means you make no particular claim as to how carefully you verified
	the key.

	1 means you believe the key is owned by the person who claims to own
	it but you could not, or did not verify the key at all. This is
	useful for a "persona" verification, where you sign the key of a
	pseudonymous user.

	2 means you did casual verification of the key. For example, this
	could mean that you verified the key fingerprint and checked the
	user ID on the key against a photo ID.

	3 means you did extensive verification of the key. For example, this
	could mean that you verified the key fingerprint with the owner of the
	key in person, and that you checked, by means of a hard to forge
	document with a photo ID (such as a passport) that the name of the key
	owner matches the name in the user ID on the key, and finally that you
	verified (by exchange of email) that the email address on the key
	belongs to the key owner.

	Note that the examples given above for levels 2 and 3 are just that:
	examples. In the end, it is up to you to decide just what "casual"
	and "extensive" mean to you.

	This option defaults to 0 (no particular claim).

	@item --min-cert-level
	@opindex min-cert-level
	When building the trust database, treat any signatures with a
	certification level below this as invalid. Defaults to 2, which
	disregards level 1 signatures. Note that level 0 "no particular
	claim" signatures are always accepted.

	@item --trusted-key @code{long key ID}
	@opindex trusted-key
	Assume that the specified key (which must be given
	as a full 8 byte key ID) is as trustworthy as one of
	your own secret keys. This option is useful if you
	don't want to keep your secret keys (or one of them)
	online but still want to be able to check the validity of a given
	recipient's or signator's key.

	@item --trust-model @code{pgp\|classic\|direct\|always\|auto}
	@opindex trust-model
	Set what trust model GnuPG should follow. The models are:

	@table @asis

	@item pgp
	@opindex trust-mode:pgp
	This is the Web of Trust combined with trust signatures as used in PGP
	5.x and later. This is the default trust model when creating a new
	trust database.

	@item classic
	@opindex trust-mode:classic
	This is the standard Web of Trust as introduced by PGP 2.

	@item direct
	@opindex trust-mode:direct
	Key validity is set directly by the user and not calculated via the
	Web of Trust.

	@item always
	@opindex trust-mode:always
	Skip key validation and assume that used keys are always fully
	valid. You generally won't use this unless you are using some
	external validation scheme. This option also suppresses the
	"[uncertain]" tag printed with signature checks when there is no
	evidence that the user ID is bound to the key. Note that this
	trust model still does not allow the use of expired, revoked, or
	disabled keys.

	@item auto
	@opindex trust-mode:auto
	Select the trust model depending on whatever the internal trust
	database says. This is the default model if such a database already
	exists.
	@end table

	@item --auto-key-locate @code{parameters}
	@itemx --no-auto-key-locate
	@opindex auto-key-locate
	GnuPG can automatically locate and retrieve keys as needed using this
	option. This happens when encrypting to an email address (in the
	"user@@example.com" form), and there are no user@@example.com keys on
	the local keyring. This option takes any number of the following
	mechanisms, in the order they are to be tried:

	@table @asis

	@item cert
	Locate a key using DNS CERT, as specified in rfc4398.

	@item pka
	Locate a key using DNS PKA.

	@item dane
	Locate a key using DANE, as specified
	in draft-ietf-dane-openpgpkey-05.txt.

	@item ldap
	Using DNS Service Discovery, check the domain in question for any LDAP
	keyservers to use. If this fails, attempt to locate the key using the
	PGP Universal method of checking @samp{ldap://keys.(thedomain)}.

	@item keyserver
	Locate a key using whatever keyserver is defined using the
	@option{--keyserver} option.

	@item keyserver-URL
	In addition, a keyserver URL as used in the @option{--keyserver} option
	may be used here to query that particular keyserver.

	@item local
	Locate the key using the local keyrings. This mechanism allows to
	select the order a local key lookup is done. Thus using
	@samp{--auto-key-locate local} is identical to
	@option{--no-auto-key-locate}.

	@item nodefault
	This flag disables the standard local key lookup, done before any of the
	mechanisms defined by the @option{--auto-key-locate} are tried. The
	position of this mechanism in the list does not matter. It is not
	required if @code{local} is also used.

	@item clear
	Clear all defined mechanisms. This is useful to override
	mechanisms given in a config file.

	@end table

	@item --keyid-format @code{short\|0xshort\|long\|0xlong}
	@opindex keyid-format
	Select how to display key IDs. "short" is the traditional 8-character
	key ID. "long" is the more accurate (but less convenient)
	16-character key ID. Add an "0x" to either to include an "0x" at the
	beginning of the key ID, as in 0x99242560. Note that this option is
	ignored if the option --with-colons is used.

	@item --keyserver @code{name}
	@opindex keyserver
	This option is deprecated - please use the @option{--keyserver} in
	@file{dirmngr.conf} instead.

	Use @code{name} as your keyserver. This is the server that
	@option{--recv-keys}, @option{--send-keys}, and @option{--search-keys}
	will communicate with to receive keys from, send keys to, and search for
	keys on. The format of the @code{name} is a URI:
	`scheme:[//]keyservername[:port]' The scheme is the type of keyserver:
	"hkp" for the HTTP (or compatible) keyservers, "ldap" for the LDAP
	keyservers, or "mailto" for the Graff email keyserver. Note that your
	particular installation of GnuPG may have other keyserver types
	available as well. Keyserver schemes are case-insensitive. After the
	keyserver name, optional keyserver configuration options may be
	provided. These are the same as the global @option{--keyserver-options}
	from below, but apply only to this particular keyserver.

	Most keyservers synchronize with each other, so there is generally no
	need to send keys to more than one server. The keyserver
	@code{hkp://keys.gnupg.net} uses round robin DNS to give a different
	keyserver each time you use it.

	@item --keyserver-options @code{name=value}
	@opindex keyserver-options
	This is a space or comma delimited string that gives options for the
	keyserver. Options can be prefixed with a `no-' to give the opposite
	meaning. Valid import-options or export-options may be used here as
	well to apply to importing (@option{--recv-key}) or exporting
	(@option{--send-key}) a key from a keyserver. While not all options
	are available for all keyserver types, some common options are:

	@table @asis

	@item include-revoked
	When searching for a key with @option{--search-keys}, include keys that
	are marked on the keyserver as revoked. Note that not all keyservers
	differentiate between revoked and unrevoked keys, and for such
	keyservers this option is meaningless. Note also that most keyservers do
	not have cryptographic verification of key revocations, and so turning
	this option off may result in skipping keys that are incorrectly marked
	as revoked.

	@item include-disabled
	When searching for a key with @option{--search-keys}, include keys that
	are marked on the keyserver as disabled. Note that this option is not
	used with HKP keyservers.

	@item auto-key-retrieve
	This option enables the automatic retrieving of keys from a keyserver
	when verifying signatures made by keys that are not on the local
	keyring.

	Note that this option makes a "web bug" like behavior possible.
	Keyserver operators can see which keys you request, so by sending you
	a message signed by a brand new key (which you naturally will not have
	on your local keyring), the operator can tell both your IP address and
	the time when you verified the signature.

	@item honor-keyserver-url
	When using @option{--refresh-keys}, if the key in question has a preferred
	keyserver URL, then use that preferred keyserver to refresh the key
	from. In addition, if auto-key-retrieve is set, and the signature
	being verified has a preferred keyserver URL, then use that preferred
	keyserver to fetch the key from. Note that this option introduces a
	"web bug": The creator of the key can see when the keys is
	refreshed. Thus this option is not enabled by default.

	@item honor-pka-record
	If auto-key-retrieve is set, and the signature being verified has a
	PKA record, then use the PKA information to fetch the key. Defaults
	to "yes".

	@item include-subkeys
	When receiving a key, include subkeys as potential targets. Note that
	this option is not used with HKP keyservers, as they do not support
	retrieving keys by subkey id.

	@item timeout
	Tell the keyserver helper program how long (in seconds) to try and
	perform a keyserver action before giving up. Note that performing
	multiple actions at the same time uses this timeout value per action.
	For example, when retrieving multiple keys via @option{--recv-keys}, the
	timeout applies separately to each key retrieval, and not to the
	@option{--recv-keys} command as a whole. Defaults to 30 seconds.

	@item http-proxy=@code{value}
	This options is deprecated.
	Set the proxy to use for HTTP and HKP keyservers.
	This overrides any proxy defined in @file{dirmngr.conf}.

	@item verbose
	This option has no more function since GnuPG 2.1. Use the
	@code{dirmngr} configuration options instead.

	@item debug
	This option has no more function since GnuPG 2.1. Use the
	@code{dirmngr} configuration options instead.

	@item check-cert
	This option has no more function since GnuPG 2.1. Use the
	@code{dirmngr} configuration options instead.

	@item ca-cert-file
	This option has no more function since GnuPG 2.1. Use the
	@code{dirmngr} configuration options instead.

	@end table

	@item --completes-needed @code{n}
	@opindex compliant-needed
	Number of completely trusted users to introduce a new
	key signer (defaults to 1).

	@item --marginals-needed @code{n}
	@opindex marginals-needed
	Number of marginally trusted users to introduce a new
	key signer (defaults to 3)

	@item --max-cert-depth @code{n}
	@opindex max-cert-depth
	Maximum depth of a certification chain (default is 5).

	@item --no-sig-cache
	@opindex no-sig-cache
	Do not cache the verification status of key signatures.
	Caching gives a much better performance in key listings. However, if
	you suspect that your public keyring is not save against write
	modifications, you can use this option to disable the caching. It
	probably does not make sense to disable it because all kind of damage
	can be done if someone else has write access to your public keyring.

	@item --auto-check-trustdb
	@itemx --no-auto-check-trustdb
	@opindex auto-check-trustdb
	If GnuPG feels that its information about the Web of Trust has to be
	updated, it automatically runs the @option{--check-trustdb} command
	internally. This may be a time consuming
	process. @option{--no-auto-check-trustdb} disables this option.

	@item --use-agent
	@itemx --no-use-agent
	@opindex use-agent
	This is dummy option. @command{@gpgname} always requires the agent.

	@item --gpg-agent-info
	@opindex gpg-agent-info
	This is dummy option. It has no effect when used with @command{gpg2}.


	@item --agent-program @var{file}
	@opindex agent-program
	Specify an agent program to be used for secret key operations. The
	default value is determined by running @command{gpgconf} with the
	option @option{--list-dirs}. Note that the pipe symbol (@code{\|}) is
	used for a regression test suite hack and may thus not be used in the
	file name.

	@item --dirmngr-program @var{file}
	@opindex dirmngr-program
	Specify a dirmngr program to be used for keyserver access. The
	default value is @file{@value{BINDIR}/dirmngr}. This is only used as a
	fallback when the environment variable @code{DIRMNGR_INFO} is not set or
	a running dirmngr cannot be connected.

	@item --no-autostart
	@opindex no-autostart
	Do not start the gpg-agent or the dirmngr if it has not yet been
	started and its service is required. This option is mostly useful on
	machines where the connection to gpg-agent has been redirected to
	another machines. If dirmngr is required on the remote machine, it
	may be started manually using @command{gpgconf --launch dirmngr}.

	@item --lock-once
	@opindex lock-once
	Lock the databases the first time a lock is requested
	and do not release the lock until the process
	terminates.

	@item --lock-multiple
	@opindex lock-multiple
	Release the locks every time a lock is no longer
	needed. Use this to override a previous @option{--lock-once}
	from a config file.

	@item --lock-never
	@opindex lock-never
	Disable locking entirely. This option should be used only in very
	special environments, where it can be assured that only one process
	is accessing those files. A bootable floppy with a stand-alone
	encryption system will probably use this. Improper usage of this
	option may lead to data and key corruption.

	@item --exit-on-status-write-error
	@opindex exit-on-status-write-error
	This option will cause write errors on the status FD to immediately
	terminate the process. That should in fact be the default but it never
	worked this way and thus we need an option to enable this, so that the
	change won't break applications which close their end of a status fd
	connected pipe too early. Using this option along with
	@option{--enable-progress-filter} may be used to cleanly cancel long
	running gpg operations.

	@item --limit-card-insert-tries @code{n}
	@opindex limit-card-insert-tries
	With @code{n} greater than 0 the number of prompts asking to insert a
	smartcard gets limited to N-1. Thus with a value of 1 gpg won't at
	all ask to insert a card if none has been inserted at startup. This
	option is useful in the configuration file in case an application does
	not know about the smartcard support and waits ad infinitum for an
	inserted card.

	@item --no-random-seed-file
	@opindex no-random-seed-file
	GnuPG uses a file to store its internal random pool over invocations.
	This makes random generation faster; however sometimes write operations
	are not desired. This option can be used to achieve that with the cost of
	slower random generation.

	@item --no-greeting
	@opindex no-greeting
	Suppress the initial copyright message.

	@item --no-secmem-warning
	@opindex no-secmem-warning
	Suppress the warning about "using insecure memory".

	@item --no-permission-warning
	@opindex permission-warning
	Suppress the warning about unsafe file and home directory (@option{--homedir})
	permissions. Note that the permission checks that GnuPG performs are
	not intended to be authoritative, but rather they simply warn about
	certain common permission problems. Do not assume that the lack of a
	warning means that your system is secure.

	Note that the warning for unsafe @option{--homedir} permissions cannot be
	suppressed in the gpg.conf file, as this would allow an attacker to
	place an unsafe gpg.conf file in place, and use this file to suppress
	warnings about itself. The @option{--homedir} permissions warning may only be
	suppressed on the command line.

	@item --no-mdc-warning
	@opindex no-mdc-warning
	Suppress the warning about missing MDC integrity protection.

	@item --require-secmem
	@itemx --no-require-secmem
	@opindex require-secmem
	Refuse to run if GnuPG cannot get secure memory. Defaults to no
	(i.e. run, but give a warning).


	@item --require-cross-certification
	@itemx --no-require-cross-certification
	@opindex require-cross-certification
	When verifying a signature made from a subkey, ensure that the cross
	certification "back signature" on the subkey is present and valid. This
	protects against a subtle attack against subkeys that can sign.
	Defaults to @option{--require-cross-certification} for
	@command{@gpgname}.

	@item --expert
	@itemx --no-expert
	@opindex expert
	Allow the user to do certain nonsensical or "silly" things like
	signing an expired or revoked key, or certain potentially incompatible
	things like generating unusual key types. This also disables certain
	warning messages about potentially incompatible actions. As the name
	implies, this option is for experts only. If you don't fully
	understand the implications of what it allows you to do, leave this
	off. @option{--no-expert} disables this option.

	@c ****** KEY RELATED OPTIONS **********
	@c *******************************************
	@node GPG Key related Options
	@subsection Key related options

	@table @gnupgtabopt

	@item --recipient @var{name}
	@itemx -r
	@opindex recipient
	Encrypt for user id @var{name}. If this option or
	@option{--hidden-recipient} is not specified, GnuPG asks for the user-id
	unless @option{--default-recipient} is given.

	@item --hidden-recipient @var{name}
	@itemx -R
	@opindex hidden-recipient
	Encrypt for user ID @var{name}, but hide the key ID of this user's
	key. This option helps to hide the receiver of the message and is a
	limited countermeasure against traffic analysis. If this option or
	@option{--recipient} is not specified, GnuPG asks for the user ID unless
	@option{--default-recipient} is given.

	@item --encrypt-to @code{name}
	@opindex encrypt-to
	Same as @option{--recipient} but this one is intended for use in the
	options file and may be used with your own user-id as an
	"encrypt-to-self". These keys are only used when there are other
	recipients given either by use of @option{--recipient} or by the asked
	user id. No trust checking is performed for these user ids and even
	disabled keys can be used.

	@item --hidden-encrypt-to @code{name}
	@opindex hidden-encrypt-to
	Same as @option{--hidden-recipient} but this one is intended for use in the
	options file and may be used with your own user-id as a hidden
	"encrypt-to-self". These keys are only used when there are other
	recipients given either by use of @option{--recipient} or by the asked user id.
	No trust checking is performed for these user ids and even disabled
	keys can be used.

	@item --no-encrypt-to
	@opindex no-encrypt-to
	Disable the use of all @option{--encrypt-to} and
	@option{--hidden-encrypt-to} keys.

	@item --group @code{name=value1 }
	@opindex group
	Sets up a named group, which is similar to aliases in email programs.
	Any time the group name is a recipient (@option{-r} or
	@option{--recipient}), it will be expanded to the values
	specified. Multiple groups with the same name are automatically merged
	into a single group.

	The values are @code{key IDs} or fingerprints, but any key description
	is accepted. Note that a value with spaces in it will be treated as
	two different values. Note also there is only one level of expansion
	--- you cannot make an group that points to another group. When used
	from the command line, it may be necessary to quote the argument to
	this option to prevent the shell from treating it as multiple
	arguments.

	@item --ungroup @code{name}
	@opindex ungroup
	Remove a given entry from the @option{--group} list.

	@item --no-groups
	@opindex no-groups
	Remove all entries from the @option{--group} list.

	@item --local-user @var{name}
	@itemx -u
	@opindex local-user
	Use @var{name} as the key to sign with. Note that this option overrides
	@option{--default-key}.

	@item --try-secret-key @var{name}
	@opindex try-secret-key
	For hidden recipients GPG needs to know the keys to use for trial
	decryption. The key set with @option{--default-key} is always tried
	first, but this is often not sufficient. This option allows to set more
	keys to be used for trial decryption. Although any valid user-id
	specification may be used for @var{name} it makes sense to use at least
	the long keyid to avoid ambiguities. Note that gpg-agent might pop up a
	pinentry for a lot keys to do the trial decryption. If you want to stop
	all further trial decryption you may use close-window button instead of
	the cancel button.

	@item --try-all-secrets
	@opindex try-all-secrets
	Don't look at the key ID as stored in the message but try all secret
	keys in turn to find the right decryption key. This option forces the
	behaviour as used by anonymous recipients (created by using
	@option{--throw-keyids} or @option{--hidden-recipient}) and might come
	handy in case where an encrypted message contains a bogus key ID.

	@item --skip-hidden-recipients
	@itemx --no-skip-hidden-recipients
	@opindex skip-hidden-recipients
	@opindex no-skip-hidden-recipients
	During decryption skip all anonymous recipients. This option helps in
	the case that people use the hidden recipients feature to hide there
	own encrypt-to key from others. If oneself has many secret keys this
	may lead to a major annoyance because all keys are tried in turn to
	decrypt something which was not really intended for it. The drawback
	of this option is that it is currently not possible to decrypt a
	message which includes real anonymous recipients.


	@end table

	@c *******************************************
	@c ****** INPUT AND OUTPUT *************
	@c *******************************************
	@node GPG Input and Output
	@subsection Input and Output

	@table @gnupgtabopt

	@item --armor
	@itemx -a
	@opindex armor
	Create ASCII armored output. The default is to create the binary
	OpenPGP format.

	@item --no-armor
	@opindex no-armor
	Assume the input data is not in ASCII armored format.

	@item --output @var{file}
	@itemx -o @var{file}
	@opindex output
	Write output to @var{file}.

	@item --max-output @code{n}
	@opindex max-output
	This option sets a limit on the number of bytes that will be generated
	when processing a file. Since OpenPGP supports various levels of
	compression, it is possible that the plaintext of a given message may be
	significantly larger than the original OpenPGP message. While GnuPG
	works properly with such messages, there is often a desire to set a
	maximum file size that will be generated before processing is forced to
	stop by the OS limits. Defaults to 0, which means "no limit".

	@item --import-options @code{parameters}
	@opindex import-options
	This is a space or comma delimited string that gives options for
	importing keys. Options can be prepended with a `no-' to give the
	opposite meaning. The options are:

	@table @asis

	@item import-local-sigs
	Allow importing key signatures marked as "local". This is not
	generally useful unless a shared keyring scheme is being used.
	Defaults to no.

	@item keep-ownertrust
	Normally possible still existing ownertrust values of a key are
	cleared if a key is imported. This is in general desirable so that
	a formerly deleted key does not automatically gain an ownertrust
	values merely due to import. On the other hand it is sometimes
	necessary to re-import a trusted set of keys again but keeping
	already assigned ownertrust values. This can be achived by using
	this option.

	@item repair-pks-subkey-bug
	During import, attempt to repair the damage caused by the PKS keyserver
	bug (pre version 0.9.6) that mangles keys with multiple subkeys. Note
	that this cannot completely repair the damaged key as some crucial data
	is removed by the keyserver, but it does at least give you back one
	subkey. Defaults to no for regular @option{--import} and to yes for
	keyserver @option{--recv-keys}.

	@item merge-only
	During import, allow key updates to existing keys, but do not allow
	any new keys to be imported. Defaults to no.

	@item import-clean
	After import, compact (remove all signatures except the
	self-signature) any user IDs from the new key that are not usable.
	Then, remove any signatures from the new key that are not usable.
	This includes signatures that were issued by keys that are not present
	on the keyring. This option is the same as running the @option{--edit-key}
	command "clean" after import. Defaults to no.

	@item import-minimal
	Import the smallest key possible. This removes all signatures except
	the most recent self-signature on each user ID. This option is the
	same as running the @option{--edit-key} command "minimize" after import.
	Defaults to no.
	@end table

	@item --export-options @code{parameters}
	@opindex export-options
	This is a space or comma delimited string that gives options for
	exporting keys. Options can be prepended with a `no-' to give the
	opposite meaning. The options are:

	@table @asis

	@item export-local-sigs
	Allow exporting key signatures marked as "local". This is not
	generally useful unless a shared keyring scheme is being used.
	Defaults to no.

	@item export-attributes
	Include attribute user IDs (photo IDs) while exporting. This is
	useful to export keys if they are going to be used by an OpenPGP
	program that does not accept attribute user IDs. Defaults to yes.

	@item export-sensitive-revkeys
	Include designated revoker information that was marked as
	"sensitive". Defaults to no.

	@c Since GnuPG 2.1 gpg-agent manages the secret key and thus the
	@c export-reset-subkey-passwd hack is not anymore justified. Such use
	@c cases may be implemented using a specialized secret key export
	@c tool.
	@c @item export-reset-subkey-passwd
	@c When using the @option{--export-secret-subkeys} command, this option resets
	@c the passphrases for all exported subkeys to empty. This is useful
	@c when the exported subkey is to be used on an unattended machine where
	@c a passphrase doesn't necessarily make sense. Defaults to no.

	@item export-clean
	Compact (remove all signatures from) user IDs on the key being
	exported if the user IDs are not usable. Also, do not export any
	signatures that are not usable. This includes signatures that were
	issued by keys that are not present on the keyring. This option is
	the same as running the @option{--edit-key} command "clean" before export
	except that the local copy of the key is not modified. Defaults to
	no.

	@item export-minimal
	Export the smallest key possible. This removes all signatures except the
	most recent self-signature on each user ID. This option is the same as
	running the @option{--edit-key} command "minimize" before export except
	that the local copy of the key is not modified. Defaults to no.
	@end table

	@item --with-colons
	@opindex with-colons
	Print key listings delimited by colons. Note that the output will be
	encoded in UTF-8 regardless of any @option{--display-charset} setting. This
	format is useful when GnuPG is called from scripts and other programs
	as it is easily machine parsed. The details of this format are
	documented in the file @file{doc/DETAILS}, which is included in the GnuPG
	source distribution.


	@item --print-pka-records
	@opindex print-pka-records
	Modify the output of the list commands to print PKA records suitable
	to put into DNS zone files. An ORIGIN line is printed before each
	record to allow diverting the records to the corresponding zone file.

	+@item --print-dane-records
	+@opindex print-dane-records
	+Modify the output of the list commands to print OpenPGP DANE records
	+suitable to put into DNS zone files. An ORIGIN line is printed before
	+each record to allow diverting the records to the corresponding zone
	+file.
	+
	@item --fixed-list-mode
	@opindex fixed-list-mode
	Do not merge primary user ID and primary key in @option{--with-colon}
	listing mode and print all timestamps as seconds since 1970-01-01.
	Since GnuPG 2.0.10, this mode is always used and thus this option is
	obsolete; it does not harm to use it though.

	@item --legacy-list-mode
	@opindex legacy-list-mode
	Revert to the pre-2.1 public key list mode. This only affects the
	human readable output and not the machine interface
	(i.e. @code{--with-colons}). Note that the legacy format does not
	allow to convey suitable information for elliptic curves.

	@item --with-fingerprint
	@opindex with-fingerprint
	Same as the command @option{--fingerprint} but changes only the format
	of the output and may be used together with another command.

	@item --with-icao-spelling
	@opindex with-icao-spelling
	Print the ICAO spelling of the fingerprint in addition to the hex digits.

	@item --with-keygrip
	@opindex with-keygrip
	Include the keygrip in the key listings.

	@item --with-secret
	@opindex with-secret
	Include info about the presence of a secret key in public key listings
	done with @code{--with-colons}.

	@end table

	@c *******************************************
	@c ****** OPENPGP OPTIONS **************
	@c *******************************************
	@node OpenPGP Options
	@subsection OpenPGP protocol specific options.

	@table @gnupgtabopt

	@item -t, --textmode
	@itemx --no-textmode
	@opindex textmode
	Treat input files as text and store them in the OpenPGP canonical text
	form with standard "CRLF" line endings. This also sets the necessary
	flags to inform the recipient that the encrypted or signed data is text
	and may need its line endings converted back to whatever the local
	system uses. This option is useful when communicating between two
	platforms that have different line ending conventions (UNIX-like to Mac,
	Mac to Windows, etc). @option{--no-textmode} disables this option, and
	is the default.

	@item --force-v3-sigs
	@itemx --no-force-v3-sigs
	@item --force-v4-certs
	@itemx --no-force-v4-certs
	These options are obsolete and have no effect since GnuPG 2.1.

	@item --force-mdc
	@opindex force-mdc
	Force the use of encryption with a modification detection code. This
	is always used with the newer ciphers (those with a blocksize greater
	than 64 bits), or if all of the recipient keys indicate MDC support in
	their feature flags.

	@item --disable-mdc
	@opindex disable-mdc
	Disable the use of the modification detection code. Note that by
	using this option, the encrypted message becomes vulnerable to a
	message modification attack.

	@item --personal-cipher-preferences @code{string}
	@opindex personal-cipher-preferences
	Set the list of personal cipher preferences to @code{string}. Use
	@command{@gpgname --version} to get a list of available algorithms,
	and use @code{none} to set no preference at all. This allows the user
	to safely override the algorithm chosen by the recipient key
	preferences, as GPG will only select an algorithm that is usable by
	all recipients. The most highly ranked cipher in this list is also
	used for the @option{--symmetric} encryption command.

	@item --personal-digest-preferences @code{string}
	@opindex personal-digest-preferences
	Set the list of personal digest preferences to @code{string}. Use
	@command{@gpgname --version} to get a list of available algorithms,
	and use @code{none} to set no preference at all. This allows the user
	to safely override the algorithm chosen by the recipient key
	preferences, as GPG will only select an algorithm that is usable by
	all recipients. The most highly ranked digest algorithm in this list
	is also used when signing without encryption
	(e.g. @option{--clearsign} or @option{--sign}).

	@item --personal-compress-preferences @code{string}
	@opindex personal-compress-preferences
	Set the list of personal compression preferences to @code{string}.
	Use @command{@gpgname --version} to get a list of available
	algorithms, and use @code{none} to set no preference at all. This
	allows the user to safely override the algorithm chosen by the
	recipient key preferences, as GPG will only select an algorithm that
	is usable by all recipients. The most highly ranked compression
	algorithm in this list is also used when there are no recipient keys
	to consider (e.g. @option{--symmetric}).

	@item --s2k-cipher-algo @code{name}
	@opindex s2k-cipher-algo
	Use @code{name} as the cipher algorithm used to protect secret keys.
	The default cipher is @value{GPGSYMENCALGO}. This cipher is also used
	for symmetric encryption with a passphrase if
	@option{--personal-cipher-preferences} and @option{--cipher-algo} is
	not given.

	@item --s2k-digest-algo @code{name}
	@opindex s2k-digest-algo
	Use @code{name} as the digest algorithm used to mangle the passphrases.
	The default algorithm is SHA-1.

	@item --s2k-mode @code{n}
	@opindex s2k-mode
	Selects how passphrases are mangled. If @code{n} is 0 a plain
	passphrase (which is not recommended) will be used, a 1 adds a salt to
	the passphrase and a 3 (the default) iterates the whole process a
	number of times (see --s2k-count). Unless @option{--rfc1991} is used,
	this mode is also used for symmetric encryption with a passphrase.

	@item --s2k-count @code{n}
	@opindex s2k-count
	Specify how many times the passphrase mangling is repeated. This
	value may range between 1024 and 65011712 inclusive. The default is
	inquired from gpg-agent. Note that not all values in the
	1024-65011712 range are legal and if an illegal value is selected,
	GnuPG will round up to the nearest legal value. This option is only
	meaningful if @option{--s2k-mode} is 3.


	@end table

	@c ***************************
	@c ***** Compliance ******
	@c ***************************
	@node Compliance Options
	@subsection Compliance options

	These options control what GnuPG is compliant to. Only one of these
	options may be active at a time. Note that the default setting of
	this is nearly always the correct one. See the INTEROPERABILITY WITH
	OTHER OPENPGP PROGRAMS section below before using one of these
	options.

	@table @gnupgtabopt

	@item --gnupg
	@opindex gnupg
	Use standard GnuPG behavior. This is essentially OpenPGP behavior
	(see @option{--openpgp}), but with some additional workarounds for common
	compatibility problems in different versions of PGP. This is the
	default option, so it is not generally needed, but it may be useful to
	override a different compliance option in the gpg.conf file.

	@item --openpgp
	@opindex openpgp
	Reset all packet, cipher and digest options to strict OpenPGP
	behavior. Use this option to reset all previous options like
	@option{--s2k-*}, @option{--cipher-algo}, @option{--digest-algo} and
	@option{--compress-algo} to OpenPGP compliant values. All PGP
	workarounds are disabled.

	@item --rfc4880
	@opindex rfc4880
	Reset all packet, cipher and digest options to strict RFC-4880
	behavior. Note that this is currently the same thing as
	@option{--openpgp}.

	@item --rfc2440
	@opindex rfc2440
	Reset all packet, cipher and digest options to strict RFC-2440
	behavior.

	@ifclear gpgtowone
	@item --rfc1991
	@opindex rfc1991
	Try to be more RFC-1991 (PGP 2.x) compliant. This option is
	deprecated will be removed in GnuPG 2.1.

	@item --pgp2
	@opindex pgp2
	Set up all options to be as PGP 2.x compliant as possible, and warn if
	an action is taken (e.g. encrypting to a non-RSA key) that will create
	a message that PGP 2.x will not be able to handle. Note that `PGP
	2.x' here means `MIT PGP 2.6.2'. There are other versions of PGP 2.x
	available, but the MIT release is a good common baseline.

	This option implies
	@option{--rfc1991 --disable-mdc --no-force-v4-certs
	--escape-from-lines --force-v3-sigs --allow-weak-digest-algos
	--cipher-algo IDEA --digest-algo MD5 --compress-algo ZIP}.
	It also disables @option{--textmode} when encrypting.

	This option is deprecated will be removed in GnuPG 2.1. The reason
	for dropping PGP-2 support is that the PGP 2 format is not anymore
	considered safe (for example due to the use of the broken MD5 algorithm).
	Note that the decryption of PGP-2 created messages will continue to work.
	@end ifclear

	@item --pgp6
	@opindex pgp6
	Set up all options to be as PGP 6 compliant as possible. This
	restricts you to the ciphers IDEA (if the IDEA plugin is installed),
	3DES, and CAST5, the hashes MD5, SHA1 and RIPEMD160, and the
	compression algorithms none and ZIP. This also disables
	--throw-keyids, and making signatures with signing subkeys as PGP 6
	does not understand signatures made by signing subkeys.

	This option implies @option{--disable-mdc --escape-from-lines}.

	@item --pgp7
	@opindex pgp7
	Set up all options to be as PGP 7 compliant as possible. This is
	identical to @option{--pgp6} except that MDCs are not disabled, and the
	list of allowable ciphers is expanded to add AES128, AES192, AES256, and
	TWOFISH.

	@item --pgp8
	@opindex pgp8
	Set up all options to be as PGP 8 compliant as possible. PGP 8 is a lot
	closer to the OpenPGP standard than previous versions of PGP, so all
	this does is disable @option{--throw-keyids} and set
	@option{--escape-from-lines}. All algorithms are allowed except for the
	SHA224, SHA384, and SHA512 digests.

	@c *******************************************
	@c ****** ESOTERIC OPTIONS *************
	@c *******************************************
	@node GPG Esoteric Options
	@subsection Doing things one usually doesn't want to do.

	@table @gnupgtabopt

	@item -n
	@itemx --dry-run
	@opindex dry-run
	Don't make any changes (this is not completely implemented).

	@item --list-only
	@opindex list-only
	Changes the behaviour of some commands. This is like @option{--dry-run} but
	different in some cases. The semantic of this command may be extended in
	the future. Currently it only skips the actual decryption pass and
	therefore enables a fast listing of the encryption keys.

	@item -i
	@itemx --interactive
	@opindex interactive
	Prompt before overwriting any files.

	@item --debug-level @var{level}
	@opindex debug-level
	Select the debug level for investigating problems. @var{level} may be
	a numeric value or by a keyword:

	@table @code
	@item none
	No debugging at all. A value of less than 1 may be used instead of
	the keyword.
	@item basic
	Some basic debug messages. A value between 1 and 2 may be used
	instead of the keyword.
	@item advanced
	More verbose debug messages. A value between 3 and 5 may be used
	instead of the keyword.
	@item expert
	Even more detailed messages. A value between 6 and 8 may be used
	instead of the keyword.
	@item guru
	All of the debug messages you can get. A value greater than 8 may be
	used instead of the keyword. The creation of hash tracing files is
	only enabled if the keyword is used.
	@end table

	How these messages are mapped to the actual debugging flags is not
	specified and may change with newer releases of this program. They are
	however carefully selected to best aid in debugging.

	@item --debug @var{flags}
	@opindex debug
	Set debugging flags. All flags are or-ed and @var{flags} may be given
	in C syntax (e.g. 0x0042) or as a comma separated list of flag names.
	To get a list of all supported flags the single word "help" can be
	used.

	@item --debug-all
	@opindex debug-all
	Set all useful debugging flags.

	@item --debug-iolbf
	@opindex debug-iolbf
	Set stdout into line buffered mode. This option is only honored when
	given on the command line.

	@item --faked-system-time @var{epoch}
	@opindex faked-system-time
	This option is only useful for testing; it sets the system time back or
	forth to @var{epoch} which is the number of seconds elapsed since the year
	1970. Alternatively @var{epoch} may be given as a full ISO time string
	(e.g. "20070924T154812").

	@item --enable-progress-filter
	@opindex enable-progress-filter
	Enable certain PROGRESS status outputs. This option allows frontends
	to display a progress indicator while gpg is processing larger files.
	There is a slight performance overhead using it.

	@item --status-fd @code{n}
	@opindex status-fd
	Write special status strings to the file descriptor @code{n}.
	See the file DETAILS in the documentation for a listing of them.

	@item --status-file @code{file}
	@opindex status-file
	Same as @option{--status-fd}, except the status data is written to file
	@code{file}.

	@item --logger-fd @code{n}
	@opindex logger-fd
	Write log output to file descriptor @code{n} and not to STDERR.

	@item --log-file @code{file}
	@itemx --logger-file @code{file}
	@opindex log-file
	Same as @option{--logger-fd}, except the logger data is written to file
	@code{file}. Note that @option{--log-file} is only implemented for
	GnuPG-2.

	@item --attribute-fd @code{n}
	@opindex attribute-fd
	Write attribute subpackets to the file descriptor @code{n}. This is most
	useful for use with @option{--status-fd}, since the status messages are
	needed to separate out the various subpackets from the stream delivered
	to the file descriptor.

	@item --attribute-file @code{file}
	@opindex attribute-file
	Same as @option{--attribute-fd}, except the attribute data is written to
	file @code{file}.

	@item --comment @code{string}
	@itemx --no-comments
	@opindex comment
	Use @code{string} as a comment string in clear text signatures and ASCII
	armored messages or keys (see @option{--armor}). The default behavior is
	not to use a comment string. @option{--comment} may be repeated multiple
	times to get multiple comment strings. @option{--no-comments} removes
	all comments. It is a good idea to keep the length of a single comment
	below 60 characters to avoid problems with mail programs wrapping such
	lines. Note that comment lines, like all other header lines, are not
	protected by the signature.

	@item --emit-version
	@itemx --no-emit-version
	@opindex emit-version
	Force inclusion of the version string in ASCII armored output. If
	given once only the name of the program and the major number is
	emitted (default), given twice the minor is also emitted, given triple
	the micro is added, and given quad an operating system identification
	is also emitted. @option{--no-emit-version} disables the version
	line.

	@item --sig-notation @code{name=value}
	@itemx --cert-notation @code{name=value}
	@itemx -N, --set-notation @code{name=value}
	@opindex sig-notation
	@opindex cert-notation
	@opindex set-notation
	Put the name value pair into the signature as notation data.
	@code{name} must consist only of printable characters or spaces, and
	must contain a '@@' character in the form keyname@@domain.example.com
	(substituting the appropriate keyname and domain name, of course). This
	is to help prevent pollution of the IETF reserved notation
	namespace. The @option{--expert} flag overrides the '@@'
	check. @code{value} may be any printable string; it will be encoded in
	UTF8, so you should check that your @option{--display-charset} is set
	correctly. If you prefix @code{name} with an exclamation mark (!), the
	notation data will be flagged as critical
	(rfc4880:5.2.3.16). @option{--sig-notation} sets a notation for data
	signatures. @option{--cert-notation} sets a notation for key signatures
	(certifications). @option{--set-notation} sets both.

	There are special codes that may be used in notation names. "%k" will
	be expanded into the key ID of the key being signed, "%K" into the
	long key ID of the key being signed, "%f" into the fingerprint of the
	key being signed, "%s" into the key ID of the key making the
	signature, "%S" into the long key ID of the key making the signature,
	"%g" into the fingerprint of the key making the signature (which might
	be a subkey), "%p" into the fingerprint of the primary key of the key
	making the signature, "%c" into the signature count from the OpenPGP
	smartcard, and "%%" results in a single "%". %k, %K, and %f are only
	meaningful when making a key signature (certification), and %c is only
	meaningful when using the OpenPGP smartcard.

	@item --sig-policy-url @code{string}
	@itemx --cert-policy-url @code{string}
	@itemx --set-policy-url @code{string}
	@opindex sig-policy-url
	@opindex cert-policy-url
	@opindex set-policy-url
	Use @code{string} as a Policy URL for signatures (rfc4880:5.2.3.20). If
	you prefix it with an exclamation mark (!), the policy URL packet will
	be flagged as critical. @option{--sig-policy-url} sets a policy url for
	data signatures. @option{--cert-policy-url} sets a policy url for key
	signatures (certifications). @option{--set-policy-url} sets both.

	The same %-expandos used for notation data are available here as well.

	@item --sig-keyserver-url @code{string}
	@opindex sig-keyserver-url
	Use @code{string} as a preferred keyserver URL for data signatures. If
	you prefix it with an exclamation mark (!), the keyserver URL packet
	will be flagged as critical.

	The same %-expandos used for notation data are available here as well.

	@item --set-filename @code{string}
	@opindex set-filename
	Use @code{string} as the filename which is stored inside messages.
	This overrides the default, which is to use the actual filename of the
	file being encrypted. Using the empty string for @var{string}
	effectively removes the filename from the output.

	@item --for-your-eyes-only
	@itemx --no-for-your-eyes-only
	@opindex for-your-eyes-only
	Set the `for your eyes only' flag in the message. This causes GnuPG to
	refuse to save the file unless the @option{--output} option is given,
	and PGP to use a "secure viewer" with a claimed Tempest-resistant font
	to display the message. This option overrides @option{--set-filename}.
	@option{--no-for-your-eyes-only} disables this option.

	@item --use-embedded-filename
	@itemx --no-use-embedded-filename
	@opindex use-embedded-filename
	Try to create a file with a name as embedded in the data. This can be
	a dangerous option as it allows to overwrite files. Defaults to no.

	@item --cipher-algo @code{name}
	@opindex cipher-algo
	Use @code{name} as cipher algorithm. Running the program with the
	command @option{--version} yields a list of supported algorithms. If
	this is not used the cipher algorithm is selected from the preferences
	stored with the key. In general, you do not want to use this option as
	it allows you to violate the OpenPGP standard.
	@option{--personal-cipher-preferences} is the safe way to accomplish the
	same thing.

	@item --digest-algo @code{name}
	@opindex digest-algo
	Use @code{name} as the message digest algorithm. Running the program
	with the command @option{--version} yields a list of supported algorithms. In
	general, you do not want to use this option as it allows you to
	violate the OpenPGP standard. @option{--personal-digest-preferences} is the
	safe way to accomplish the same thing.

	@item --compress-algo @code{name}
	@opindex compress-algo
	Use compression algorithm @code{name}. "zlib" is RFC-1950 ZLIB
	compression. "zip" is RFC-1951 ZIP compression which is used by PGP.
	"bzip2" is a more modern compression scheme that can compress some
	things better than zip or zlib, but at the cost of more memory used
	during compression and decompression. "uncompressed" or "none"
	disables compression. If this option is not used, the default
	behavior is to examine the recipient key preferences to see which
	algorithms the recipient supports. If all else fails, ZIP is used for
	maximum compatibility.

	ZLIB may give better compression results than ZIP, as the compression
	window size is not limited to 8k. BZIP2 may give even better
	compression results than that, but will use a significantly larger
	amount of memory while compressing and decompressing. This may be
	significant in low memory situations. Note, however, that PGP (all
	versions) only supports ZIP compression. Using any algorithm other
	than ZIP or "none" will make the message unreadable with PGP. In
	general, you do not want to use this option as it allows you to
	violate the OpenPGP standard. @option{--personal-compress-preferences} is the
	safe way to accomplish the same thing.

	@item --cert-digest-algo @code{name}
	@opindex cert-digest-algo
	Use @code{name} as the message digest algorithm used when signing a
	key. Running the program with the command @option{--version} yields a
	list of supported algorithms. Be aware that if you choose an algorithm
	that GnuPG supports but other OpenPGP implementations do not, then some
	users will not be able to use the key signatures you make, or quite
	possibly your entire key.

	@item --disable-cipher-algo @code{name}
	@opindex disable-cipher-algo
	Never allow the use of @code{name} as cipher algorithm.
	The given name will not be checked so that a later loaded algorithm
	will still get disabled.

	@item --disable-pubkey-algo @code{name}
	@opindex disable-pubkey-algo
	Never allow the use of @code{name} as public key algorithm.
	The given name will not be checked so that a later loaded algorithm
	will still get disabled.

	@item --throw-keyids
	@itemx --no-throw-keyids
	@opindex throw-keyids
	Do not put the recipient key IDs into encrypted messages. This helps to
	hide the receivers of the message and is a limited countermeasure
	against traffic analysis.@footnote{Using a little social engineering
	anyone who is able to decrypt the message can check whether one of the
	other recipients is the one he suspects.} On the receiving side, it may
	slow down the decryption process because all available secret keys must
	be tried. @option{--no-throw-keyids} disables this option. This option
	is essentially the same as using @option{--hidden-recipient} for all
	recipients.

	@item --not-dash-escaped
	@opindex not-dash-escaped
	This option changes the behavior of cleartext signatures
	so that they can be used for patch files. You should not
	send such an armored file via email because all spaces
	and line endings are hashed too. You can not use this
	option for data which has 5 dashes at the beginning of a
	line, patch files don't have this. A special armor header
	line tells GnuPG about this cleartext signature option.

	@item --escape-from-lines
	@itemx --no-escape-from-lines
	@opindex escape-from-lines
	Because some mailers change lines starting with "From " to ">From " it
	is good to handle such lines in a special way when creating cleartext
	signatures to prevent the mail system from breaking the signature. Note
	that all other PGP versions do it this way too. Enabled by
	default. @option{--no-escape-from-lines} disables this option.

	@item --passphrase-repeat @code{n}
	@opindex passphrase-repeat
	Specify how many times @command{@gpgname} will request a new
	passphrase be repeated. This is useful for helping memorize a
	passphrase. Defaults to 1 repetition.

	@item --passphrase-fd @code{n}
	@opindex passphrase-fd
	Read the passphrase from file descriptor @code{n}. Only the first line
	will be read from file descriptor @code{n}. If you use 0 for @code{n},
	the passphrase will be read from STDIN. This can only be used if only
	one passphrase is supplied.

	Note that this passphrase is only used if the option @option{--batch}
	has also been given. This is different from GnuPG version 1.x.

	@item --passphrase-file @code{file}
	@opindex passphrase-file
	Read the passphrase from file @code{file}. Only the first line will
	be read from file @code{file}. This can only be used if only one
	passphrase is supplied. Obviously, a passphrase stored in a file is
	of questionable security if other users can read this file. Don't use
	this option if you can avoid it.
	Note that this passphrase is only used if the option @option{--batch}
	has also been given. This is different from GnuPG version 1.x.

	@item --passphrase @code{string}
	@opindex passphrase
	Use @code{string} as the passphrase. This can only be used if only one
	passphrase is supplied. Obviously, this is of very questionable
	security on a multi-user system. Don't use this option if you can
	avoid it.
	Note that this passphrase is only used if the option @option{--batch}
	has also been given. This is different from GnuPG version 1.x.

	@item --pinentry-mode @code{mode}
	@opindex pinentry-mode
	Set the pinentry mode to @code{mode}. Allowed values for @code{mode}
	are:
	@table @asis
	@item default
	Use the default of the agent, which is @code{ask}.
	@item ask
	Force the use of the Pinentry.
	@item cancel
	Emulate use of Pinentry's cancel button.
	@item error
	Return a Pinentry error (``No Pinentry'').
	@item loopback
	Redirect Pinentry queries to the caller. Note that in contrast to
	Pinentry the user is not prompted again if he enters a bad password.
	@end table

	@item --command-fd @code{n}
	@opindex command-fd
	This is a replacement for the deprecated shared-memory IPC mode.
	If this option is enabled, user input on questions is not expected
	from the TTY but from the given file descriptor. It should be used
	together with @option{--status-fd}. See the file doc/DETAILS in the source
	distribution for details on how to use it.

	@item --command-file @code{file}
	@opindex command-file
	Same as @option{--command-fd}, except the commands are read out of file
	@code{file}

	@item --allow-non-selfsigned-uid
	@itemx --no-allow-non-selfsigned-uid
	@opindex allow-non-selfsigned-uid
	Allow the import and use of keys with user IDs which are not
	self-signed. This is not recommended, as a non self-signed user ID is
	trivial to forge. @option{--no-allow-non-selfsigned-uid} disables.

	@item --allow-freeform-uid
	@opindex allow-freeform-uid
	Disable all checks on the form of the user ID while generating a new
	one. This option should only be used in very special environments as
	it does not ensure the de-facto standard format of user IDs.

	@item --ignore-time-conflict
	@opindex ignore-time-conflict
	GnuPG normally checks that the timestamps associated with keys and
	signatures have plausible values. However, sometimes a signature
	seems to be older than the key due to clock problems. This option
	makes these checks just a warning. See also @option{--ignore-valid-from} for
	timestamp issues on subkeys.

	@item --ignore-valid-from
	@opindex ignore-valid-from
	GnuPG normally does not select and use subkeys created in the future.
	This option allows the use of such keys and thus exhibits the
	pre-1.0.7 behaviour. You should not use this option unless there
	is some clock problem. See also @option{--ignore-time-conflict} for timestamp
	issues with signatures.

	@item --ignore-crc-error
	@opindex ignore-crc-error
	The ASCII armor used by OpenPGP is protected by a CRC checksum against
	transmission errors. Occasionally the CRC gets mangled somewhere on
	the transmission channel but the actual content (which is protected by
	the OpenPGP protocol anyway) is still okay. This option allows GnuPG
	to ignore CRC errors.

	@item --ignore-mdc-error
	@opindex ignore-mdc-error
	This option changes a MDC integrity protection failure into a warning.
	This can be useful if a message is partially corrupt, but it is
	necessary to get as much data as possible out of the corrupt message.
	However, be aware that a MDC protection failure may also mean that the
	message was tampered with intentionally by an attacker.

	@item --allow-weak-digest-algos
	@opindex allow-weak-digest-algos
	Signatures made with the broken MD5 algorithm are normally rejected
	with an ``invalid digest algorithm'' message. This option allows the
	verification of signatures made with such weak algorithms.

	@item --no-default-keyring
	@opindex no-default-keyring
	Do not add the default keyrings to the list of keyrings. Note that
	GnuPG will not operate without any keyrings, so if you use this option
	and do not provide alternate keyrings via @option{--keyring} or
	@option{--secret-keyring}, then GnuPG will still use the default public or
	secret keyrings.

	@item --skip-verify
	@opindex skip-verify
	Skip the signature verification step. This may be
	used to make the decryption faster if the signature
	verification is not needed.

	@item --with-key-data
	@opindex with-key-data
	Print key listings delimited by colons (like @option{--with-colons}) and
	print the public key data.

	@item --fast-list-mode
	@opindex fast-list-mode
	Changes the output of the list commands to work faster; this is achieved
	by leaving some parts empty. Some applications don't need the user ID
	and the trust information given in the listings. By using this options
	they can get a faster listing. The exact behaviour of this option may
	change in future versions. If you are missing some information, don't
	use this option.

	@item --no-literal
	@opindex no-literal
	This is not for normal use. Use the source to see for what it might be useful.

	@item --set-filesize
	@opindex set-filesize
	This is not for normal use. Use the source to see for what it might be useful.

	@item --show-session-key
	@opindex show-session-key
	Display the session key used for one message. See
	@option{--override-session-key} for the counterpart of this option.

	We think that Key Escrow is a Bad Thing; however the user should have
	the freedom to decide whether to go to prison or to reveal the content
	of one specific message without compromising all messages ever
	encrypted for one secret key.

	You can also use this option if you receive an encrypted message which
	is abusive or offensive, to prove to the administrators of the
	messaging system that the ciphertext transmitted corresponds to an
	inappropriate plaintext so they can take action against the offending
	user.

	@item --override-session-key @code{string}
	@opindex override-session-key
	Don't use the public key but the session key @code{string}. The format
	of this string is the same as the one printed by
	@option{--show-session-key}. This option is normally not used but comes
	handy in case someone forces you to reveal the content of an encrypted
	message; using this option you can do this without handing out the
	secret key.

	@item --ask-sig-expire
	@itemx --no-ask-sig-expire
	@opindex ask-sig-expire
	When making a data signature, prompt for an expiration time. If this
	option is not specified, the expiration time set via
	@option{--default-sig-expire} is used. @option{--no-ask-sig-expire}
	disables this option.

	@item --default-sig-expire
	@opindex default-sig-expire
	The default expiration time to use for signature expiration. Valid
	values are "0" for no expiration, a number followed by the letter d
	(for days), w (for weeks), m (for months), or y (for years) (for
	example "2m" for two months, or "5y" for five years), or an absolute
	date in the form YYYY-MM-DD. Defaults to "0".

	@item --ask-cert-expire
	@itemx --no-ask-cert-expire
	@opindex ask-cert-expire
	When making a key signature, prompt for an expiration time. If this
	option is not specified, the expiration time set via
	@option{--default-cert-expire} is used. @option{--no-ask-cert-expire}
	disables this option.

	@item --default-cert-expire
	@opindex default-cert-expire
	The default expiration time to use for key signature expiration.
	Valid values are "0" for no expiration, a number followed by the
	letter d (for days), w (for weeks), m (for months), or y (for years)
	(for example "2m" for two months, or "5y" for five years), or an
	absolute date in the form YYYY-MM-DD. Defaults to "0".

	@item --allow-secret-key-import
	@opindex allow-secret-key-import
	This is an obsolete option and is not used anywhere.

	@item --allow-multiple-messages
	@item --no-allow-multiple-messages
	@opindex allow-multiple-messages
	Allow processing of multiple OpenPGP messages contained in a single file
	or stream. Some programs that call GPG are not prepared to deal with
	multiple messages being processed together, so this option defaults to
	no. Note that versions of GPG prior to 1.4.7 always allowed multiple
	messages.

	Warning: Do not use this option unless you need it as a temporary
	workaround!


	@item --enable-special-filenames
	@opindex enable-special-filenames
	This options enables a mode in which filenames of the form
	@file{-&n}, where n is a non-negative decimal number,
	refer to the file descriptor n and not to a file with that name.

	@item --no-expensive-trust-checks
	@opindex no-expensive-trust-checks
	Experimental use only.

	@item --preserve-permissions
	@opindex preserve-permissions
	Don't change the permissions of a secret keyring back to user
	read/write only. Use this option only if you really know what you are doing.

	@item --default-preference-list @code{string}
	@opindex default-preference-list
	Set the list of default preferences to @code{string}. This preference
	list is used for new keys and becomes the default for "setpref" in the
	edit menu.

	@item --default-keyserver-url @code{name}
	@opindex default-keyserver-url
	Set the default keyserver URL to @code{name}. This keyserver will be
	used as the keyserver URL when writing a new self-signature on a key,
	which includes key generation and changing preferences.

	@item --list-config
	@opindex list-config
	Display various internal configuration parameters of GnuPG. This option
	is intended for external programs that call GnuPG to perform tasks, and
	is thus not generally useful. See the file @file{doc/DETAILS} in the
	source distribution for the details of which configuration items may be
	listed. @option{--list-config} is only usable with
	@option{--with-colons} set.

	@item --list-gcrypt-config
	@opindex list-gcrypt-config
	Display various internal configuration parameters of Libgcrypt.

	@item --gpgconf-list
	@opindex gpgconf-list
	This command is similar to @option{--list-config} but in general only
	internally used by the @command{gpgconf} tool.

	@item --gpgconf-test
	@opindex gpgconf-test
	This is more or less dummy action. However it parses the configuration
	file and returns with failure if the configuration file would prevent
	@command{gpg} from startup. Thus it may be used to run a syntax check
	on the configuration file.

	Use a good password for your user account and a good passphrase

	are very easy to write and so you should protect your "~/.gnupg/"
	directory very well.

	Keep in mind that, if this program is used over a network (telnet), it
	is very easy to spy out your passphrase!

	If you are going to verify detached signatures, make sure that the
	program knows about it; either give both filenames on the command line
	or use @samp{-} to specify STDIN.

	@mansect interoperability
	@chapheading INTEROPERABILITY WITH OTHER OPENPGP PROGRAMS

	GnuPG tries to be a very flexible implementation of the OpenPGP
	standard. In particular, GnuPG implements many of the optional parts
	of the standard, such as the SHA-512 hash, and the ZLIB and BZIP2
	compression algorithms. It is important to be aware that not all
	OpenPGP programs implement these optional algorithms and that by
	forcing their use via the @option{--cipher-algo},
	@option{--digest-algo}, @option{--cert-digest-algo}, or
	@option{--compress-algo} options in GnuPG, it is possible to create a
	perfectly valid OpenPGP message, but one that cannot be read by the
	intended recipient.

	There are dozens of variations of OpenPGP programs available, and each
	supports a slightly different subset of these optional algorithms.
	For example, until recently, no (unhacked) version of PGP supported
	the BLOWFISH cipher algorithm. A message using BLOWFISH simply could
	not be read by a PGP user. By default, GnuPG uses the standard
	OpenPGP preferences system that will always do the right thing and
	create messages that are usable by all recipients, regardless of which
	OpenPGP program they use. Only override this safe default if you
	really know what you are doing.

	If you absolutely must override the safe default, or if the preferences
	on a given key are invalid for some reason, you are far better off using
	the @option{--pgp6}, @option{--pgp7}, or @option{--pgp8} options. These
	options are safe as they do not force any particular algorithms in
	violation of OpenPGP, but rather reduce the available algorithms to a
	"PGP-safe" list.

	@mansect bugs
	@chapheading BUGS

	On older systems this program should be installed as setuid(root). This
	is necessary to lock memory pages. Locking memory pages prevents the
	operating system from writing memory pages (which may contain
	passphrases or other sensitive material) to disk. If you get no
	warning message about insecure memory your operating system supports
	locking without being root. The program drops root privileges as soon
	as locked memory is allocated.

	Note also that some systems (especially laptops) have the ability to
	``suspend to disk'' (also known as ``safe sleep'' or ``hibernate'').
	This writes all memory to disk before going into a low power or even
	powered off mode. Unless measures are taken in the operating system
	to protect the saved memory, passphrases or other sensitive material
	may be recoverable from it later.

	Before you report a bug you should first search the mailing list
	archives for similar problems and second check whether such a bug has
	already been reported to our bug tracker at http://bugs.gnupg.org .

	@node Unattended Usage of GPG
	@section Unattended Usage

	@command{gpg} is often used as a backend engine by other software. To help
	with this a machine interface has been defined to have an unambiguous
	way to do this. The options @option{--status-fd} and @option{--batch}
	are almost always required for this.

	@menu
	* Unattended GPG key generation:: Unattended key generation
	@end menu


	@node Unattended GPG key generation
	@subsection Unattended key generation

	The command @option{--gen-key} may be used along with the option
	@option{--batch} for unattended key generation. The parameters are
	either read from stdin or given as a file on the command line.
	The format of the parameter file is as follows:

	@itemize @bullet
	@item Text only, line length is limited to about 1000 characters.
	@item UTF-8 encoding must be used to specify non-ASCII characters.
	@item Empty lines are ignored.
	@item Leading and trailing while space is ignored.
	@item A hash sign as the first non white space character indicates
	a comment line.
	@item Control statements are indicated by a leading percent sign, the
	arguments are separated by white space from the keyword.
	@item Parameters are specified by a keyword, followed by a colon. Arguments
	are separated by white space.
	@item
	The first parameter must be @samp{Key-Type}; control statements may be
	placed anywhere.
	@item
	The order of the parameters does not matter except for @samp{Key-Type}
	which must be the first parameter. The parameters are only used for
	the generated keyblock (primary and subkeys); parameters from previous
	sets are not used. Some syntactically checks may be performed.
	@item
	Key generation takes place when either the end of the parameter file
	is reached, the next @samp{Key-Type} parameter is encountered or at the
	control statement @samp{%commit} is encountered.
	@end itemize

	@noindent
	Control statements:

	@table @asis

	@item %echo @var{text}
	Print @var{text} as diagnostic.

	@item %dry-run
	Suppress actual key generation (useful for syntax checking).

	@item %commit
	Perform the key generation. Note that an implicit commit is done at
	the next @asis{Key-Type} parameter.

	@item %pubring @var{filename}
	@itemx %secring @var{filename}
	Do not write the key to the default or commandline given keyring but
	to @var{filename}. This must be given before the first commit to take
	place, duplicate specification of the same filename is ignored, the
	last filename before a commit is used. The filename is used until a
	new filename is used (at commit points) and all keys are written to
	that file. If a new filename is given, this file is created (and
	overwrites an existing one). For GnuPG versions prior to 2.1, both
	control statements must be given. For GnuPG 2.1 and later
	@samp{%secring} is a no-op.

	@item %ask-passphrase
	@itemx %no-ask-passphrase
	This option is a no-op for GnuPG 2.1 and later.

	@item %no-protection
	Using this option allows the creation of keys without any passphrase
	protection. This option is mainly intended for regression tests.

	@item %transient-key
	If given the keys are created using a faster and a somewhat less
	secure random number generator. This option may be used for keys
	which are only used for a short time and do not require full
	cryptographic strength. It takes only effect if used together with
	the control statement @samp{%no-protection}.

	@end table

	@noindent
	General Parameters:

	@table @asis

	@item Key-Type: @var{algo}
	Starts a new parameter block by giving the type of the primary
	key. The algorithm must be capable of signing. This is a required
	parameter. @var{algo} may either be an OpenPGP algorithm number or a
	string with the algorithm name. The special value @samp{default} may
	be used for @var{algo} to create the default key type; in this case a
	@samp{Key-Usage} shall not be given and @samp{default} also be used
	for @samp{Subkey-Type}.

	@item Key-Length: @var{nbits}
	The requested length of the generated key in bits. The default is
	returned by running the command @samp{gpg2 --gpgconf-list}.

	@item Key-Grip: @var{hexstring}
	This is optional and used to generate a CSR or certificate for an
	already existing key. Key-Length will be ignored when given.

	@item Key-Usage: @var{usage-list}
	Space or comma delimited list of key usages. Allowed values are
	@samp{encrypt}, @samp{sign}, and @samp{auth}. This is used to
	generate the key flags. Please make sure that the algorithm is
	capable of this usage. Note that OpenPGP requires that all primary
	keys are capable of certification, so no matter what usage is given
	here, the @samp{cert} flag will be on. If no @samp{Key-Usage} is
	specified and the @samp{Key-Type} is not @samp{default}, all allowed
	usages for that particular algorithm are used; if it is not given but
	@samp{default} is used the usage will be @samp{sign}.

	@item Subkey-Type: @var{algo}
	This generates a secondary key (subkey). Currently only one subkey
	can be handled. See also @samp{Key-Type} above.

	@item Subkey-Length: @var{nbits}
	Length of the secondary key (subkey) in bits. The default is returned
	by running the command @samp{gpg2 --gpgconf-list}".

	@item Subkey-Usage: @var{usage-list}
	Key usage lists for a subkey; similar to @samp{Key-Usage}.

	@item Passphrase: @var{string}
	If you want to specify a passphrase for the secret key, enter it here.
	Default is to use the Pinentry dialog to ask for a passphrase.

	@item Name-Real: @var{name}
	@itemx Name-Comment: @var{comment}
	@itemx Name-Email: @var{email}
	The three parts of a user name. Remember to use UTF-8 encoding here.
	If you don't give any of them, no user ID is created.

	@item Expire-Date: @var{iso-date}\|(@var{number}[d\|w\|m\|y])
	Set the expiration date for the key (and the subkey). It may either
	be entered in ISO date format (e.g. "20000815T145012") or as number of
	days, weeks, month or years after the creation date. The special
	notation "seconds=N" is also allowed to specify a number of seconds
	since creation. Without a letter days are assumed. Note that there
	is no check done on the overflow of the type used by OpenPGP for
	timestamps. Thus you better make sure that the given value make
	sense. Although OpenPGP works with time intervals, GnuPG uses an
	absolute value internally and thus the last year we can represent is
	2105.

	@item Creation-Date: @var{iso-date}
	Set the creation date of the key as stored in the key information and
	which is also part of the fingerprint calculation. Either a date like
	"1986-04-26" or a full timestamp like "19860426T042640" may be used.
	The time is considered to be UTC. The special notation "seconds=N"
	may be used to directly specify a the number of seconds since Epoch
	(Unix time). If it is not given the current time is used.

	@item Preferences: @var{string}
	Set the cipher, hash, and compression preference values for this key.
	This expects the same type of string as the sub-command @samp{setpref}
	in the @option{--edit-key} menu.

	@item Revoker: @var{algo}:@var{fpr} [sensitive]
	Add a designated revoker to the generated key. Algo is the public key
	algorithm of the designated revoker (i.e. RSA=1, DSA=17, etc.)
	@var{fpr} is the fingerprint of the designated revoker. The optional
	@samp{sensitive} flag marks the designated revoker as sensitive
	information. Only v4 keys may be designated revokers.

	@item Keyserver: @var{string}
	This is an optional parameter that specifies the preferred keyserver
	URL for the key.

	@item Handle: @var{string}
	This is an optional parameter only used with the status lines
	KEY_CREATED and KEY_NOT_CREATED. @var{string} may be up to 100
	characters and should not contain spaces. It is useful for batch key
	generation to associate a key parameter block with a status line.
