Hi gpg-ers, I'm interested in utilizing GnuPG in software that I'm writing and it seems that communicating with the gpg-agent over a unix socket using the Assuan protocol is best suited for my use case but am open to other options if there are better approaches.
My problem lies in getting the assuan protocol in practice to match up with the documentation here<http://www.gnupg.org/documentation/manuals/gnupg-devel/Agent-Protocol.html#Agent-Protocol> . When attempting to use the GENKEY command as described here<http://www.gnupg.org/documentation/manuals/gnupg-devel/Agent-GENKEY.html#Agent-GENKEY> as new user I always get an invalid data error when using the example client requests: socat /tmp/gpg-xxxxx/S.gpg-agent - > OK Pleased to meet you, process 280 > GENKEY > INQUIRE KEYPARAM > D (genkey (rsa (nbits 4096))) > END > ERR 67108943 Invalid data <GPG Agent> > GENKEY > INQUIRE KEYPARAM > D (genkey (rsa (nbits 2048))) > END > ERR 67108943 Invalid data <GPG Agent> > GENKEY > INQUIRE KEYPARAM > D (genkey (rsa (nbits 1024))) > END > ERR 67108943 Invalid data <GPG Agent> Starting gpg-agent with --debug 10 I get the following debug output: [user@host]:~$ gpg-agent --daemon --no-detach --debug 10 gpg-agent[]: directory `/home/user/.gnupg' created gpg-agent[]: directory `/home/user/.gnupg/private-keys-v1.d' created gpg-agent[]: failed to convert keyparam: Invalid length specifier in S-expression gpg-agent[]: command genkey failed: Invalid data gpg-agent[]: failed to convert keyparam: Invalid length specifier in S-expression gpg-agent[]: command genkey failed: Invalid data gpg-agent[]: failed to convert keyparam: Invalid length specifier in S-expression gpg-agent[]: command genkey failed: Invalid data This seems to suggest that there exist more parameters to the GENKEY command than are documented. What am I missing here? Taking a step back is this a good solution for 3rd party software to use GPG or are there libraries I should be using instead to accomplish the communication? Diving into the code to see if I can't figure it out but maybe you can help. Thanks, -Alan Meekins
