Description

I think there must be an issue about this already but I could not find it.

My most important wish for a "professional" Gpg4win product is that it should be easier to deploy a configuration of GnuPG. For Example the compliance de-vs option. Currently our institutional deployment runs a login script for this.

Kleopatra uses the library KConfig to have a very nice configuration interface.
https://userbase.kde.org/KDE_System_Administration/Kiosk/Introduction

For GnuPG my proposal is:

Read config from /etc/gnupg/

-> No new magic please like the profiles and all that stuff. Just read a "gpg.conf" "gpg-agent.conf" etc. from that location. Treat it as normal config files.

Afterwards read the config from the GnuPG home dir.

If an option in the system wide configuration is marked with a "=" sign or something like that at the beginning of the line treat it as immutable. Otherwise prefer the user option.

E.g. if =enable-crl-checks is in the system wide config a "disable-crl-checks" should be ignored in the user config. Without an equal sign CRL checks should be disabled because the user has explicitly set it.

I'm mostly interested in Windows for this.

Okay, we now have global conf files in master. The extra flags to ignore or force certain options will be added to libgpg-error.

All done in master with the latest libgpg-error (see T4859). There is always a global configure file in /etc/gnupg (or whatever "gpgconf --list-dirs sysconfdir" prints). The name of the configure file is the same as the user config file (gpg.conf, gpgsm.conf, gpg-agent.conf, ...) but for gpg.conf no versioned config names are used.

Example usage in gpg.conf

[force]
compliance de-vs
encrypt-to  0x12345678
[-force]
[ignore]
no-encrypt-to

Which enforces the use of a compliance option and makes sure that all encrypted data is also encrypted to the given key. The ignore meta command is then used to ignore any use of --no-encrypt-to in config files and the command line.

@dkg You might find this interesting. Debian could do stuff in /etc/gnupg/gpg.conf or /etc/gnupg/dirmngr.conf without patching GnuPG to change some defaults.

I wanted this badly as a distributor.

Arggh, gpgconf uses its own option parser so adding the global config file there will require some extra work.

i'd be unlikely to ship anything as /etc/gnupg/gpg.conf or /etc/gnupg/dirmngr.conf just because of the mess that admins have to deal with when shipped config files change.

But i agree that some sysadmins who use debian might find this feature super useful, and i'd be happy to advertise it in the debian NEWS file when it lands in a version that we can distribute.

There are likely some bugs in the new code and I also want to do some improvements; see rGb4f1159a5bd7. But things should basically work as before and thus I set this again to testing
