@c ******** OPERATIONAL COMMANDS ***********
@c *******************************************
@node Operational GPGSM Commands
@subsection Commands to select the type of operation
@table @gnupgtabopt
@item --encrypt
@opindex encrypt
Perform an encryption. The keys the data is encrypted to must be set
using the option @option{--recipient}.
@item --decrypt
@opindex decrypt
Perform a decryption; the type of input is automatically determined. It
may either be in binary form or PEM encoded; automatic determination of
base-64 encoding is not done.
@item --sign
@opindex sign
Create a digital signature. The key used is either the fist one found
in the keybox or those set with the @option{--local-user} option.
@item --verify
@opindex verify
Check a signature file for validity. Depending on the arguments a
detached signature may also be checked.
@item --server
@opindex server
Run in server mode and wait for commands on the @code{stdin}.
@item --call-dirmngr @var{command} [@var{args}]
@opindex call-dirmngr
Behave as a Dirmngr client issuing the request @var{command} with the
optional list of @var{args}. The output of the Dirmngr is printed
stdout. Please note that file names given as arguments should have an
absolute file name (i.e. commencing with @code{/}) because they are
passed verbatim to the Dirmngr and the working directory of the
Dirmngr might not be the same as the one of this client. Currently it
is not possible to pass data via stdin to the Dirmngr. @var{command}
should not contain spaces.
This is command is required for certain maintaining tasks of the dirmngr
where a dirmngr must be able to call back to @command{gpgsm}. See the Dirmngr
manual for details.
@item --call-protect-tool @var{arguments}
@opindex call-protect-tool
Certain maintenance operations are done by an external program call
@command{gpg-protect-tool}; this is usually not installed in a directory
listed in the PATH variable. This command provides a simple wrapper to
access this tool. @var{arguments} are passed verbatim to this command;
use @samp{--help} to get a list of supported operations.
@end table
@c *******************************************
@c ******* CERTIFICATE MANAGEMENT **********
@c *******************************************
@node Certificate Management
@subsection How to manage the certificates and keys
@table @gnupgtabopt
@item --generate-key
@opindex generate-key
@itemx --gen-key
@opindex gen-key
This command allows the creation of a certificate signing request or a
self-signed certificate. It is commonly used along with the
@option{--output} option to save the created CSR or certificate into a
file. If used with the @option{--batch} a parameter file is used to
create the CSR or certificate and it is further possible to create
non-self-signed certificates.
@item --list-keys
@itemx -k
@opindex list-keys
List all available certificates stored in the local key database.
Note that the displayed data might be reformatted for better human
readability and illegal characters are replaced by safe substitutes.
@item --list-secret-keys
@itemx -K
@opindex list-secret-keys
List all available certificates for which a corresponding a secret key
is available.
@item --list-external-keys @var{pattern}
@opindex list-keys
List certificates matching @var{pattern} using an external server. This
utilizes the @code{dirmngr} service.
@item --list-chain
@opindex list-chain
Same as @option{--list-keys} but also prints all keys making up the chain.
@item --dump-cert
@itemx --dump-keys
@opindex dump-cert
@opindex dump-keys
List all available certificates stored in the local key database using a
format useful mainly for debugging.
@item --dump-chain
@opindex dump-chain
Same as @option{--dump-keys} but also prints all keys making up the chain.
@item --dump-secret-keys
@opindex dump-secret-keys
List all available certificates for which a corresponding a secret key
is available using a format useful mainly for debugging.
@item --dump-external-keys @var{pattern}
@opindex dump-external-keys
List certificates matching @var{pattern} using an external server.
This utilizes the @code{dirmngr} service. It uses a format useful
mainly for debugging.
@item --keydb-clear-some-cert-flags
@opindex keydb-clear-some-cert-flags
This is a debugging aid to reset certain flags in the key database
which are used to cache certain certificate stati. It is especially
useful if a bad CRL or a weird running OCSP responder did accidentally
revoke certificate. There is no security issue with this command
because @command{gpgsm} always make sure that the validity of a certificate is
checked right before it is used.
@item --delete-keys @var{pattern}
@opindex delete-keys
Delete the keys matching @var{pattern}. Note that there is no command
to delete the secret part of the key directly. In case you need to do
this, you should run the command @code{gpgsm --dump-secret-keys KEYID}
before you delete the key, copy the string of hex-digits in the
``keygrip'' line and delete the file consisting of these hex-digits
and the suffix @code{.key} from the @file{private-keys-v1.d} directory
below our GnuPG home directory (usually @file{~/.gnupg}).
@item --export [@var{pattern}]
@opindex export
Export all certificates stored in the Keybox or those specified by the
optional @var{pattern}. Those pattern consist of a list of user ids
(@pxref{how-to-specify-a-user-id}). When used along with the
@option{--armor} option a few informational lines are prepended before
each block. There is one limitation: As there is no commonly agreed
upon way to pack more than one certificate into an ASN.1 structure,
the binary export (i.e. without using @option{armor}) works only for
the export of one certificate. Thus it is required to specify a
@var{pattern} which yields exactly one certificate. Ephemeral
certificate are only exported if all @var{pattern} are given as
fingerprints or keygrips.
@item --export-secret-key-p12 @var{key-id}
@opindex export-secret-key-p12
Export the private key and the certificate identified by @var{key-id}
using the PKCS#12 format. When used with the @code{--armor} option a few
informational lines are prepended to the output. Note, that the PKCS#12
format is not very secure and proper transport security should be used
to convey the exported key. (@xref{option --p12-charset}.)
@item --export-secret-key-p8 @var{key-id}
@itemx --export-secret-key-raw @var{key-id}
@opindex export-secret-key-p8
@opindex export-secret-key-raw
Export the private key of the certificate identified by @var{key-id}
with any encryption stripped. The @code{...-raw} command exports in
PKCS#1 format; the @code{...-p8} command exports in PKCS#8 format.
When used with the @code{--armor} option a few informational lines are
prepended to the output. These commands are useful to prepare a key
for use on a TLS server.
@item --import [@var{files}]
@opindex import
Import the certificates from the PEM or binary encoded files as well as
from signed-only messages. This command may also be used to import a
secret key from a PKCS#12 file.
@item --learn-card
@opindex learn-card
Read information about the private keys from the smartcard and import
the certificates from there. This command utilizes the @command{gpg-agent}
and in turn the @command{scdaemon}.
@item --change-passphrase @var{user_id}
@opindex change-passphrase
@itemx --passwd @var{user_id}
@opindex passwd
Change the passphrase of the private key belonging to the certificate
specified as @var{user_id}. Note, that changing the passphrase/PIN of a
smartcard is not yet supported.

@node 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
@anchor{gpgsm-option --options}
@item --options @var{file}
@opindex options
Reads configuration from @var{file} instead of from the default
per-user configuration file. The default configuration file is named
@file{gpgsm.conf} and expected in the @file{.gnupg} directory directly
below the home directory of the user.
@include opt-homedir.texi
@item -v
@item --verbose
@opindex v
@opindex verbose
Outputs additional information while running.
You can increase the verbosity by giving several
verbose commands to @command{gpgsm}, such as @samp{-vv}.
-@item --ldapserver @var{string}
-@itemx --keyserver @var{string}
-@opindex ldapserver
+@item --keyserver @var{string}
@opindex keyserver
-Add an LDAP server to use for X.509 certificate and CRL lookup. This
-option can be given multiple times to configure more than one LDAP
-server. Note that in general @command{dirmngr} should be configured
-with the list of LDAP servers; if this option is also configured here,
-it is used in addition to those configured in dirmngr. For the syntax
-see the description of dirmngr's ldapserver option.
+This is a deprecated option. It was used to add an LDAP server to use
+for X.509 certificate and CRL lookup. The alias @option{--ldapserver}
+existed from version 2.2.28 to 2.2.33 but is now entirely ignored.
+
+LDAP servers must be given in the configuration for @command{dirmngr}.
+
@item --policy-file @var{filename}
@opindex policy-file
Change the default name of the policy file to @var{filename}.
@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 the command @command{gpgconf}.
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 @acronym{CRL} checks. The
default value is @file{@value{BINDIR}/dirmngr}.
@item --prefer-system-dirmngr
@opindex prefer-system-dirmngr
This option is obsolete and ignored.
@item --disable-dirmngr
Entirely disable the use of the Dirmngr.
@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 --no-secmem-warning
@opindex no-secmem-warning
Do not print a warning when the so called "secure memory" cannot be used.
@item --log-file @var{file}
@opindex log-file
When running in server mode, append all logging output to @var{file}.
Use @file{socket://} to log to socket.
@end table
@c *******************************************
@c ******** CERTIFICATE OPTIONS ************
@c *******************************************
@node Certificate Options
@subsection Certificate related options
@table @gnupgtabopt
@item --enable-policy-checks
@itemx --disable-policy-checks
@opindex enable-policy-checks
@opindex disable-policy-checks
By default policy checks are enabled. These options may be used to
change it.
@item --enable-crl-checks
@itemx --disable-crl-checks
@opindex enable-crl-checks
@opindex disable-crl-checks
By default the @acronym{CRL} checks are enabled and the DirMngr is
used to check for revoked certificates. The disable option is most
useful with an off-line network connection to suppress this check and
also to avoid that new certificates introduce a web bug by including a
certificate specific CRL DP. The disable option also disables an
issuer certificate lookup via the authorityInfoAccess property of the
certificate; the @option{--enable-issuer-key-retrieve} can be used
to make use of that property anyway.
@item --enable-trusted-cert-crl-check
@itemx --disable-trusted-cert-crl-check
@opindex enable-trusted-cert-crl-check
@opindex disable-trusted-cert-crl-check
By default the @acronym{CRL} for trusted root certificates are checked
like for any other certificates. This allows a CA to revoke its own
certificates voluntary without the need of putting all ever issued
certificates into a CRL. The disable option may be used to switch this
extra check off. Due to the caching done by the Dirmngr, there will not be
any noticeable performance gain. Note, that this also disables possible
OCSP checks for trusted root certificates. A more specific way of
disabling this check is by adding the ``relax'' keyword to the root CA
line of the @file{trustlist.txt}
@item --force-crl-refresh
@opindex force-crl-refresh
Tell the dirmngr to reload the CRL for each request. For better
performance, the dirmngr will actually optimize this by suppressing
the loading for short time intervals (e.g. 30 minutes). This option
is useful to make sure that a fresh CRL is available for certificates
hold in the keybox. The suggested way of doing this is by using it
along with the option @option{--with-validation} for a key listing
command. This option should not be used in a configuration file.
@item --enable-issuer-based-crl-check
@opindex enable-issuer-based-crl-check
Run a CRL check even for certificates which do not have any CRL
distribution point. This requires that a suitable LDAP server has
been configured in Dirmngr and that the CRL can be found using the
issuer. This option reverts to what GnuPG did up to version 2.2.20.
This option is in general not useful.
@item --enable-ocsp
@itemx --disable-ocsp
@opindex enable-ocsp
@opindex disable-ocsp
By default @acronym{OCSP} checks are disabled. The enable option may
be used to enable OCSP checks via Dirmngr. If @acronym{CRL} checks
are also enabled, CRLs will be used as a fallback if for some reason an
OCSP request will not succeed. Note, that you have to allow OCSP
requests in Dirmngr's configuration too (option
@option{--allow-ocsp}) and configure Dirmngr properly. If you do not do
so you will get the error code @samp{Not supported}.
@item --auto-issuer-key-retrieve
@opindex auto-issuer-key-retrieve
If a required certificate is missing while validating the chain of
certificates, try to load that certificate from an external location.
This usually means that Dirmngr is employed to search for the
certificate. Note that this option makes a "web bug" like behavior
possible. LDAP server 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 keybox), the operator can tell both your IP
address and the time when you verified the signature.
@anchor{gpgsm-option --validation-model}
@item --validation-model @var{name}
@opindex validation-model
This option changes the default validation model. The only possible
values are "shell" (which is the default), "chain" which forces the
use of the chain model and "steed" for a new simplified model. The
chain model is also used if an option in the @file{trustlist.txt} or
an attribute of the certificate requests it. However the standard
model (shell) is in that case always tried first.
@item --ignore-cert-extension @var{oid}
@opindex ignore-cert-extension
Add @var{oid} to the list of ignored certificate extensions. The
@var{oid} is expected to be in dotted decimal form, like
@code{2.5.29.3}. This option may be used more than once. Critical
flagged certificate extensions matching one of the OIDs in the list
are treated as if they are actually handled and thus the certificate
will not be rejected due to an unknown critical extension. Use this
option with care because extensions are usually flagged as critical
for a reason.
@end table
@c *******************************************
@c *********** INPUT AND OUTPUT ************
@c *******************************************
@node Input and Output
@subsection Input and Output
@table @gnupgtabopt
@item --armor
@itemx -a
@opindex armor
Create PEM encoded output. Default is binary output.
@item --base64
@opindex base64
Create Base-64 encoded output; i.e. PEM without the header lines.
@item --assume-armor
@opindex assume-armor
Assume the input data is PEM encoded. Default is to autodetect the
encoding but this is may fail.
@item --assume-base64
@opindex assume-base64
Assume the input data is plain base-64 encoded.
@item --assume-binary
@opindex assume-binary
Assume the input data is binary encoded.
@anchor{option --p12-charset}
@item --p12-charset @var{name}
@opindex p12-charset
@command{gpgsm} uses the UTF-8 encoding when encoding passphrases for
PKCS#12 files. This option may be used to force the passphrase to be
encoded in the specified encoding @var{name}. This is useful if the
application used to import the key uses a different encoding and thus
will not be able to import a file generated by @command{gpgsm}. Commonly
used values for @var{name} are @code{Latin1} and @code{CP850}. Note
that @command{gpgsm} itself automagically imports any file with a
passphrase encoded to the most commonly used encodings.
@item --default-key @var{user_id}
@opindex default-key
Use @var{user_id} as the standard key for signing. This key is used if
no other key has been defined as a signing key. Note, that the first
@option{--local-users} option also sets this key if it has not yet been
set; however @option{--default-key} always overrides this.
@item --local-user @var{user_id}
@item -u @var{user_id}
@opindex local-user
Set the user(s) to be used for signing. The default is the first
secret key found in the database.
@item --recipient @var{name}
@itemx -r
@opindex recipient
Encrypt to the user id @var{name}. There are several ways a user id
may be given (@pxref{how-to-specify-a-user-id}).
@item --output @var{file}
@itemx -o @var{file}
@opindex output
Write output to @var{file}. The default is to write it to stdout.
@anchor{gpgsm-option --with-key-data}
@item --with-key-data
@opindex with-key-data
Displays extra information with the @code{--list-keys} commands. Especially
a line tagged @code{grp} is printed which tells you the keygrip of a
key. This string is for example used as the file name of the
secret key. Implies @code{--with-colons}.
@anchor{gpgsm-option --with-validation}
@item --with-validation
@opindex with-validation
When doing a key listing, do a full validation check for each key and
print the result. This is usually a slow operation because it
requires a CRL lookup and other operations.
When used along with @option{--import}, a validation of the certificate to
import is done and only imported if it succeeds the test. Note that
this does not affect an already available certificate in the DB.
This option is therefore useful to simply verify a certificate.
@item --with-md5-fingerprint
For standard key listings, also print the MD5 fingerprint of the
certificate.
@item --with-keygrip
Include the keygrip in standard key listings. Note that the keygrip is
always listed in @option{--with-colons} mode.
@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 ************* CMS OPTIONS ***************
@c *******************************************
@node CMS Options
@subsection How to change how the CMS is created
@table @gnupgtabopt
@item --include-certs @var{n}
@opindex include-certs
Using @var{n} of -2 includes all certificate except for the root cert,
-1 includes all certs, 0 does not include any certs, 1 includes only the
signers cert and all other positive values include up to @var{n}
certificates starting with the signer cert. The default is -2.
@item --cipher-algo @var{oid}
@opindex cipher-algo
Use the cipher algorithm with the ASN.1 object identifier @var{oid} for
encryption. For convenience the strings @code{3DES}, @code{AES} and
@code{AES256} may be used instead of their OIDs. The default is
@code{AES} (2.16.840.1.101.3.4.1.2).
@item --digest-algo @code{name}
Use @code{name} as the message digest algorithm. Usually this
algorithm is deduced from the respective signing certificate. This
option forces the use of the given algorithm and may lead to severe
interoperability problems.
@end table
@c *******************************************
@c ******** ESOTERIC OPTIONS ***************
@c *******************************************
@node Esoteric Options
@subsection Doing things one usually do not want to do
@table @gnupgtabopt
@item --extra-digest-algo @var{name}
@opindex extra-digest-algo
Sometimes signatures are broken in that they announce a different digest
algorithm than actually used. @command{gpgsm} uses a one-pass data
processing model and thus needs to rely on the announced digest
algorithms to properly hash the data. As a workaround this option may
be used to tell @command{gpgsm} to also hash the data using the algorithm
@var{name}; this slows processing down a little bit but allows verification of
such broken signatures. If @command{gpgsm} prints an error like
``digest algo 8 has not been enabled'' you may want to try this option,
with @samp{SHA256} for @var{name}.
@item --compliance @var{string}
@opindex compliance
Set the compliance mode. Valid values are shown when using "help" for
@var{string}.
@item --min-rsa-length @var{n}
@opindex min-rsa-length
This option adjusts the compliance mode "de-vs" for stricter key size
requirements. For example, a value of 3000 turns rsa2048 and dsa2048
keys into non-VS-NfD compliant keys.
@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 --with-ephemeral-keys
@opindex with-ephemeral-keys
Include ephemeral flagged keys in the output of key listings. Note
that they are included anyway if the key specification for a listing
is given as fingerprint or keygrip.
@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
This option is only useful for debugging and the behaviour may change
at any time without notice; using @code{--debug-levels} is the
preferred method to select the debug verbosity. FLAGS are bit encoded
and may be given in usual C-Syntax. The currently defined bits are:
@table @code
@item 0 (1)
X.509 or OpenPGP protocol related data
@item 1 (2)
values of big number integers
@item 2 (4)
low level crypto operations
@item 5 (32)
memory allocation
@item 6 (64)
caching
@item 7 (128)
show memory statistics
@item 9 (512)
write hashed data to files named @code{dbgmd-000*}
@item 10 (1024)
trace Assuan protocol
@end table
Note, that all flags set using this option may get overridden by
@code{--debug-level}.
@item --debug-all
@opindex debug-all
Same as @code{--debug=0xffffffff}
@item --debug-allow-core-dump
@opindex debug-allow-core-dump
Usually @command{gpgsm} tries to avoid dumping core by well written code and by
disabling core dumps for security reasons. However, bugs are pretty
durable beasts and to squash them it is sometimes useful to have a core
dump. This option enables core dumps unless the Bad Thing happened
before the option parsing.
@item --debug-no-chain-validation
@opindex debug-no-chain-validation
This is actually not a debugging option but only useful as such. It
lets @command{gpgsm} bypass all certificate chain validation checks.
@item --debug-ignore-expiration
@opindex debug-ignore-expiration
This is actually not a debugging option but only useful as such. It
lets @command{gpgsm} ignore all notAfter dates, this is used by the regression
tests.
@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.
@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 --request-origin @var{origin}
@opindex request-origin
Tell gpgsm to assume that the operation ultimately originated at
@var{origin}. Depending on the origin certain restrictions are applied
and the Pinentry may include an extra note on the origin. Supported
values for @var{origin} are: @code{local} which is the default,
@code{remote} to indicate a remote origin or @code{browser} for an
operation requested by a web browser.
@item --no-common-certs-import
@opindex no-common-certs-import
Suppress the import of common certificates on keybox creation.
@end table
All the long options may also be given in the configuration file after
stripping off the two leading dashes.

@node GPGSM Configuration
@section Configuration files
There are a few configuration files to control certain aspects of
@command{gpgsm}'s operation. Unless noted, they are expected in the
current home directory (@pxref{option --homedir}).
@table @file
@item gpgsm.conf
@efindex gpgsm.conf
This is the standard configuration file read by @command{gpgsm} on
startup. It may contain any valid long option; the leading two dashes
may not be entered and the option may not be abbreviated. This default
name may be changed on the command line (@pxref{gpgsm-option --options}).
You should backup this file.
@item policies.txt
@efindex policies.txt
This is a list of allowed CA policies. This file should list the
object identifiers of the policies line by line. Empty lines and
lines starting with a hash mark are ignored. Policies missing in this
file and not marked as critical in the certificate will print only a
warning; certificates with policies marked as critical and not listed
in this file will fail the signature verification. You should backup
this file.
For example, to allow only the policy 2.289.9.9, the file should look
like this:
@c man:.RS
@example
# Allowed policies
2.289.9.9
@end example
@c man:.RE
@item qualified.txt
@efindex qualified.txt
This is the list of root certificates used for qualified certificates.
They are defined as certificates capable of creating legally binding
signatures in the same way as handwritten signatures are. Comments
start with a hash mark and empty lines are ignored. Lines do have a
length limit but this is not a serious limitation as the format of the
entries is fixed and checked by @command{gpgsm}: A non-comment line starts with
optional whitespace, followed by exactly 40 hex characters, white space
and a lowercased 2 letter country code. Additional data delimited with
by a white space is current ignored but might late be used for other
purposes.
Note that even if a certificate is listed in this file, this does not
mean that the certificate is trusted; in general the certificates listed
in this file need to be listed also in @file{trustlist.txt}.
This is a global file an installed in the data directory
(e.g. @file{@value{DATADIR}/qualified.txt}). GnuPG installs a suitable
file with root certificates as used in Germany. As new Root-CA
certificates may be issued over time, these entries may need to be
updated; new distributions of this software should come with an updated
list but it is still the responsibility of the Administrator to check
that this list is correct.
Every time @command{gpgsm} uses a certificate for signing or verification
this file will be consulted to check whether the certificate under
question has ultimately been issued by one of these CAs. If this is the
case the user will be informed that the verified signature represents a
legally binding (``qualified'') signature. When creating a signature
using such a certificate an extra prompt will be issued to let the user
confirm that such a legally binding signature shall really be created.
Because this software has not yet been approved for use with such
certificates, appropriate notices will be shown to indicate this fact.
@item help.txt
@efindex help.txt
This is plain text file with a few help entries used with
@command{pinentry} as well as a large list of help items for
@command{gpg} and @command{gpgsm}. The standard file has English help
texts; to install localized versions use filenames like @file{help.LL.txt}
with LL denoting the locale. GnuPG comes with a set of predefined help
files in the data directory (e.g. @file{@value{DATADIR}/gnupg/help.de.txt})
and allows overriding of any help item by help files stored in the
system configuration directory (e.g. @file{@value{SYSCONFDIR}/help.de.txt}).
For a reference of the help file's syntax, please see the installed
@file{help.txt} file.
@item com-certs.pem
@efindex com-certs.pem
This file is a collection of common certificates used to populated a
newly created @file{pubring.kbx}. An administrator may replace this
file with a custom one. The format is a concatenation of PEM encoded
X.509 certificates. This global file is installed in the data directory
(e.g. @file{@value{DATADIR}/com-certs.pem}).
@end table
@c man:.RE
Note that on larger installations, it is useful to put predefined files
into the directory @file{/etc/skel/.gnupg/} so that newly created users
start up with a working configuration. For existing users a small
helper script is provided to create these files (@pxref{addgnupghome}).
For internal purposes @command{gpgsm} creates and maintains a few other files;
they all live in the current home directory (@pxref{option
--homedir}). Only @command{gpgsm} may modify these files.
@table @file
@item pubring.kbx
@efindex pubring.kbx
This a database file storing the certificates as well as meta
information. For debugging purposes the tool @command{kbxutil} may be
used to show the internal structure of this file. You should backup
this file.
@item random_seed
@efindex random_seed
This content of this file is used to maintain the internal state of the
random number generator across invocations. The same file is used by
other programs of this software too.
@item S.gpg-agent
@efindex S.gpg-agent
If this file exists
@command{gpgsm} will first try to connect to this socket for
accessing @command{gpg-agent} before starting a new @command{gpg-agent}
instance. Under Windows this socket (which in reality be a plain file
describing a regular TCP listening port) is the standard way of
connecting the @command{gpg-agent}.

@node Unattended Usage
@section Unattended Usage
@command{gpgsm} 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. This is most likely used with the @code{--server} command
but may also be used in the standard operation mode by using the
@code{--status-fd} option.
@menu
* Automated signature checking:: Automated signature checking.
* CSR and certificate creation:: CSR and certificate creation.
@end menu
@node Automated signature checking
@subsection Automated signature checking
It is very important to understand the semantics used with signature
verification. Checking a signature is not as simple as it may sound and
so the operation is a bit complicated. In most cases it is required
to look at several status lines. Here is a table of all cases a signed
message may have:
@table @asis
@item The signature is valid
This does mean that the signature has been successfully verified, the
certificates are all sane. However there are two subcases with
important information: One of the certificates may have expired or a
signature of a message itself as expired. It is a sound practise to
consider such a signature still as valid but additional information
should be displayed. Depending on the subcase @command{gpgsm} will issue
these status codes:
@table @asis
@item signature valid and nothing did expire
@code{GOODSIG}, @code{VALIDSIG}, @code{TRUST_FULLY}
@item signature valid but at least one certificate has expired
@code{EXPKEYSIG}, @code{VALIDSIG}, @code{TRUST_FULLY}
@item signature valid but expired
@code{EXPSIG}, @code{VALIDSIG}, @code{TRUST_FULLY}
Note, that this case is currently not implemented.
@end table
@item The signature is invalid
This means that the signature verification failed (this is an indication
of a transfer error, a program error or tampering with the message).
@command{gpgsm} issues one of these status codes sequences:
@table @code
@item @code{BADSIG}
@item @code{GOODSIG}, @code{VALIDSIG} @code{TRUST_NEVER}
@end table
@item Error verifying a signature
For some reason the signature could not be verified, i.e. it cannot be
decided whether the signature is valid or invalid. A common reason for
this is a missing certificate.
@end table
@node CSR and certificate creation
@subsection CSR and certificate creation
The command @option{--generate-key} may be used along with the option
@option{--batch} to either create a certificate signing request (CSR)
or an X.509 certificate. This is controlled by a parameter file; the
format of this 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 CSR/certificate; 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.
@c %certfile <filename>
@c [Not yet implemented!]
@c Do not write the certificate to the keyDB but to <filename>.
@c This must be given before the first
@c commit to take place, duplicate specification of the same filename
@c is ignored, the last filename before a commit is used.
@c The filename is used until a new filename is used (at commit points)
@c and all keys are written to that file. If a new filename is given,
@c this file is created (and overwrites an existing one).
@c Both control statements must be given.
@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. The only supported value for @var{algo} is @samp{rsa}.
@item Key-Length: @var{nbits}
The requested length of a generated key in bits. Defaults to 3072.
@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 usage, allowed values are
@samp{encrypt}, @samp{sign} and @samp{cert}. This is used to generate
the keyUsage extension. Please make sure that the algorithm is
capable of this usage. Default is to allow encrypt and sign.
@item Name-DN: @var{subject-name}
This is the Distinguished Name (DN) of the subject in RFC-2253 format.
@item Name-Email: @var{string}
This is an email address for the altSubjectName. This parameter is
optional but may occur several times to add several email addresses to
a certificate.
@item Name-DNS: @var{string}
The is an DNS name for the altSubjectName. This parameter is optional
but may occur several times to add several DNS names to a certificate.
@item Name-URI: @var{string}
This is an URI for the altSubjectName. This parameter is optional but
may occur several times to add several URIs to a certificate.
@end table
@noindent
Additional parameters used to create a certificate (in contrast to a
certificate signing request):
@table @asis
@item Serial: @var{sn}
If this parameter is given an X.509 certificate will be generated.
@var{sn} is expected to be a hex string representing an unsigned
integer of arbitrary length. The special value @samp{random} can be
used to create a 64 bit random serial number.
@item Issuer-DN: @var{issuer-name}
This is the DN name of the issuer in RFC-2253 format. If it is not set
it will default to the subject DN and a special GnuPG extension will
be included in the certificate to mark it as a standalone certificate.
@item Creation-Date: @var{iso-date}
@itemx Not-Before: @var{iso-date}
Set the notBefore date of the certificate. Either a date like
@samp{1986-04-26} or @samp{1986-04-26 12:00} or a standard ISO
timestamp like @samp{19860426T042640} may be used. The time is
considered to be UTC. If it is not given the current date is used.
@item Expire-Date: @var{iso-date}
@itemx Not-After: @var{iso-date}
Set the notAfter date of the certificate. Either a date like
@samp{2063-04-05} or @samp{2063-04-05 17:00} or a standard ISO
timestamp like @samp{20630405T170000} may be used. The time is
considered to be UTC. If it is not given a default value in the not
too far future is used.
@item Signing-Key: @var{keygrip}
This gives the keygrip of the key used to sign the certificate. If it
is not given a self-signed certificate will be created. For
compatibility with future versions, it is suggested to prefix the
keygrip with a @samp{&}.
@item Hash-Algo: @var{hash-algo}
Use @var{hash-algo} for this CSR or certificate. The supported hash
algorithms are: @samp{sha1}, @samp{sha256}, @samp{sha384} and
@samp{sha512}; they may also be specified with uppercase letters. The
default is @samp{sha256}.

@node GPGSM Protocol
@section The Protocol the Server Mode Uses
Description of the protocol used to access @command{GPGSM}.
@command{GPGSM} does implement the Assuan protocol and in addition
provides a regular command line interface which exhibits a full client
to this protocol (but uses internal linking). To start
@command{gpgsm} as a server the command line the option
@code{--server} must be used. Additional options are provided to
select the communication method (i.e. the name of the socket).
We assume that the connection has already been established; see the
Assuan manual for details.

@end menu
@node GPGSM ENCRYPT
@subsection Encrypting a Message
Before encryption can be done the recipient must be set using the
command:
@example
RECIPIENT @var{userID}
@end example
Set the recipient for the encryption. @var{userID} should be the
internal representation of the key; the server may accept any other way
of specification. If this is a valid and trusted recipient the server
does respond with OK, otherwise the return is an ERR with the reason why
the recipient cannot be used, the encryption will then not be done for
this recipient. If the policy is not to encrypt at all if not all
recipients are valid, the client has to take care of this. All
@code{RECIPIENT} commands are cumulative until a @code{RESET} or an
successful @code{ENCRYPT} command.
@example
INPUT FD[=@var{n}] [--armor|--base64|--binary]
@end example
Set the file descriptor for the message to be encrypted to @var{n}.
Obviously the pipe must be open at that point, the server establishes
its own end. If the server returns an error the client should consider
this session failed. If @var{n} is not given, this commands uses the
last file descriptor passed to the application.
@xref{fun-assuan_sendfd, ,the assuan_sendfd function,assuan,the Libassuan
manual}, on how to do descriptor passing.
The @code{--armor} option may be used to advise the server that the
input data is in @acronym{PEM} format, @code{--base64} advises that a
raw base-64 encoding is used, @code{--binary} advises of raw binary
input (@acronym{BER}). If none of these options is used, the server
tries to figure out the used encoding, but this may not always be
correct.
@example
OUTPUT FD[=@var{n}] [--armor|--base64]
@end example
Set the file descriptor to be used for the output (i.e. the encrypted
message). Obviously the pipe must be open at that point, the server
establishes its own end. If the server returns an error the client
should consider this session failed.
The option @option{--armor} encodes the output in @acronym{PEM} format, the
@option{--base64} option applies just a base-64 encoding. No option
creates binary output (@acronym{BER}).
The actual encryption is done using the command
@example
ENCRYPT
@end example
It takes the plaintext from the @code{INPUT} command, writes to the
ciphertext to the file descriptor set with the @code{OUTPUT} command,
take the recipients from all the recipients set so far. If this command
fails the clients should try to delete all output currently done or
otherwise mark it as invalid. @command{GPGSM} does ensure that there
will not be any
security problem with leftover data on the output in this case.
This command should in general not fail, as all necessary checks have
been done while setting the recipients. The input and output pipes are
closed.
@node GPGSM DECRYPT
@subsection Decrypting a message
Input and output FDs are set the same way as in encryption, but
@code{INPUT} refers to the ciphertext and @code{OUTPUT} to the plaintext. There
is no need to set recipients. @command{GPGSM} automatically strips any
@acronym{S/MIME} headers from the input, so it is valid to pass an
entire MIME part to the INPUT pipe.
The decryption is done by using the command
@example
DECRYPT
@end example
It performs the decrypt operation after doing some check on the internal
state (e.g. that all needed data has been set). Because it utilizes
the GPG-Agent for the session key decryption, there is no need to ask
the client for a protecting passphrase - GpgAgent takes care of this by
requesting this from the user.
@node GPGSM SIGN
@subsection Signing a Message
Signing is usually done with these commands:
@example
INPUT FD[=@var{n}] [--armor|--base64|--binary]
@end example
This tells @command{GPGSM} to read the data to sign from file descriptor @var{n}.
@example
OUTPUT FD[=@var{m}] [--armor|--base64]
@end example
Write the output to file descriptor @var{m}. If a detached signature is
requested, only the signature is written.
@example
SIGN [--detached]
@end example
Sign the data set with the @code{INPUT} command and write it to the sink set by
@code{OUTPUT}. With @code{--detached}, a detached signature is created
(surprise).
The key used for signing is the default one or the one specified in
the configuration file. To get finer control over the keys, it is
possible to use the command
@example
SIGNER @var{userID}
@end example
to set the signer's key. @var{userID} should be the
internal representation of the key; the server may accept any other way
of specification. If this is a valid and trusted recipient the server
does respond with OK, otherwise the return is an ERR with the reason why
the key cannot be used, the signature will then not be created using
this key. If the policy is not to sign at all if not all
keys are valid, the client has to take care of this. All
@code{SIGNER} commands are cumulative until a @code{RESET} is done.
Note that a @code{SIGN} does not reset this list of signers which is in
contrast to the @code{RECIPIENT} command.
@node GPGSM VERIFY
@subsection Verifying a Message
To verify a message the command:
@example
VERIFY
@end example
is used. It does a verify operation on the message send to the input FD.
The result is written out using status lines. If an output FD was
given, the signed text will be written to that. If the signature is a
detached one, the server will inquire about the signed material and the
client must provide it.
@node GPGSM GENKEY
@subsection Generating a Key
This is used to generate a new keypair, store the secret part in the
@acronym{PSE} and the public key in the key database. We will probably
add optional commands to allow the client to select whether a hardware
token is used to store the key. Configuration options to
@command{GPGSM} can be used to restrict the use of this command.
@example
GENKEY
@end example
@command{GPGSM} checks whether this command is allowed and then does an
INQUIRY to get the key parameters, the client should then send the
key parameters in the native format:
@example
S: INQUIRE KEY_PARAM native
C: D foo:fgfgfg
C: D bar
C: END
@end example
Please note that the server may send Status info lines while reading the
data lines from the client. After this the key generation takes place
and the server eventually does send an ERR or OK response. Status lines
may be issued as a progress indicator.
@node GPGSM LISTKEYS
@subsection List available keys
@anchor{gpgsm-cmd listkeys}
To list the keys in the internal database or using an external key
provider, the command:
@example
LISTKEYS @var{pattern}
@end example
is used. To allow multiple patterns (which are ORed during the search)
quoting is required: Spaces are to be translated into "+" or into "%20";
in turn this requires that the usual escape quoting rules are done.
@example
LISTSECRETKEYS @var{pattern}
@end example
Lists only the keys where a secret key is available.
The list commands are affected by the option
@example
OPTION list-mode=@var{mode}
@end example
where mode may be:
@table @code
@item 0
Use default (which is usually the same as 1).
@item 1
List only the internal keys.
@item 2
List only the external keys.
@item 3
List internal and external keys.
@end table
Note that options are valid for the entire session.
@node GPGSM EXPORT
@subsection Export certificates
To export certificate from the internal key database the command:
@example
EXPORT [--data [--armor] [--base64]] [--] @var{pattern}
@end example
is used. To allow multiple patterns (which are ORed) quoting is
required: Spaces are to be translated into "+" or into "%20"; in turn
this requires that the usual escape quoting rules are done.
If the @option{--data} option has not been given, the format of the
output depends on what was set with the @code{OUTPUT} command. When using
@acronym{PEM} encoding a few informational lines are prepended.
If the @option{--data} has been given, a target set via @code{OUTPUT} is
ignored and the data is returned inline using standard
@code{D}-lines. This avoids the need for an extra file descriptor. In
this case the options @option{--armor} and @option{--base64} may be used
in the same way as with the @code{OUTPUT} command.
@node GPGSM IMPORT
@subsection Import certificates
To import certificates into the internal key database, the command
@example
IMPORT [--re-import]
@end example
is used. The data is expected on the file descriptor set with the
@code{INPUT} command. Certain checks are performed on the
certificate. Note that the code will also handle PKCS#12 files and
import private keys; a helper program is used for that.
With the option @option{--re-import} the input data is expected to a be
a linefeed separated list of fingerprints. The command will re-import
the corresponding certificates; that is they are made permanent by
removing their ephemeral flag.
@node GPGSM DELETE
@subsection Delete certificates
To delete a certificate the command
@example
DELKEYS @var{pattern}
@end example
is used. To allow multiple patterns (which are ORed) quoting is
required: Spaces are to be translated into "+" or into "%20"; in turn
this requires that the usual escape quoting rules are done.
The certificates must be specified unambiguously otherwise an error is
returned.
@node GPGSM GETAUDITLOG
@subsection Retrieve an audit log
@anchor{gpgsm-cmd getauditlog}
This command is used to retrieve an audit log.
@example
GETAUDITLOG [--data] [--html]
@end example
If @option{--data} is used, the audit log is send using D-lines
instead of being sent to the file descriptor given by an @code{OUTPUT}
command. If @option{--html} is used, the output is formatted as an
XHTML block. This is designed to be incorporated into a HTML
document.
@node GPGSM GETINFO
@subsection Return information about the process
This is a multipurpose function to return a variety of information.
@example
GETINFO @var{what}
@end example
The value of @var{what} specifies the kind of information returned:
@table @code
@item version
Return the version of the program.
@item pid
Return the process id of the process.
@item agent-check
Return OK if the agent is running.
@item cmd_has_option @var{cmd} @var{opt}
Return OK if the command @var{cmd} implements the option @var{opt}.
The leading two dashes usually used with @var{opt} shall not be given.
@item offline
Return OK if the connection is in offline mode. This may be either
due to a @code{OPTION offline=1} or due to @command{gpgsm} being
started with option @option{--disable-dirmngr}.
@end table
@node GPGSM OPTION
@subsection Session options
The standard Assuan option handler supports these options.
@example
OPTION @var{name}[=@var{value}]
@end example
These @var{name}s are recognized:
@table @code
@item putenv
Change the session's environment to be passed via gpg-agent to
Pinentry. @var{value} is a string of the form
@code{<KEY>[=[<STRING>]]}. If only @code{<KEY>} is given the
environment variable @code{<KEY>} is removed from the session
environment, if @code{<KEY>=} is given that environment variable is
set to the empty string, and if @code{<STRING>} is given it is set to
that string.
@item display
@efindex DISPLAY
Set the session environment variable @code{DISPLAY} is set to @var{value}.
@item ttyname
@efindex GPG_TTY
Set the session environment variable @code{GPG_TTY} is set to @var{value}.
@item ttytype
@efindex TERM
Set the session environment variable @code{TERM} is set to @var{value}.
@item lc-ctype
@efindex LC_CTYPE
Set the session environment variable @code{LC_CTYPE} is set to @var{value}.
@item lc-messages
@efindex LC_MESSAGES
Set the session environment variable @code{LC_MESSAGES} is set to @var{value}.
@item xauthority
@efindex XAUTHORITY
Set the session environment variable @code{XAUTHORITY} is set to @var{value}.
@item pinentry-user-data
@efindex PINENTRY_USER_DATA
Set the session environment variable @code{PINENTRY_USER_DATA} is set
to @var{value}.
@item include-certs
This option overrides the command line option
@option{--include-certs}. A @var{value} of -2 includes all
certificates except for the root certificate, -1 includes all
certificates, 0 does not include any certificates, 1 includes only the
signers certificate and all other positive values include up to
@var{value} certificates starting with the signer cert.
@item list-mode
@xref{gpgsm-cmd listkeys}.
@item list-to-output
If @var{value} is true the output of the list commands
(@pxref{gpgsm-cmd listkeys}) is written to the file descriptor set
with the last @code{OUTPUT} command. If @var{value} is false the output is
written via data lines; this is the default.
@item with-validation
If @var{value} is true for each listed certificate the validation
status is printed. This may result in the download of a CRL or the
user being asked about the trustworthiness of a root certificate. The
default is given by a command line option (@pxref{gpgsm-option
--with-validation}).
@item with-secret
If @var{value} is true certificates with a corresponding private key
are marked by the list commands.
@item validation-model
This option overrides the command line option
@option{validation-model} for the session.
(@xref{gpgsm-option --validation-model}.)
@item with-key-data
This option globally enables the command line option
@option{--with-key-data}. (@xref{gpgsm-option --with-key-data}.)
@item enable-audit-log
If @var{value} is true data to write an audit log is gathered.
(@xref{gpgsm-cmd getauditlog}.)
@item allow-pinentry-notify
If this option is used notifications about the launch of a Pinentry
are passed back to the client.
@item with-ephemeral-keys
If @var{value} is true ephemeral certificates are included in the
output of the list commands.
@item no-encrypt-to
If this option is used all keys set by the command line option
@option{--encrypt-to} are ignored.
@item offline
If @var{value} is true or @var{value} is not given all network access
is disabled for this session. This is the same as the command line
option @option{--disable-dirmngr}.
