I do not see why --export-ssh-key exports only a single key (the latest). In my configuration, I have private key material for each device split into multiple subkeys. They are all active and valid authentication keys, and should be included in the output.
I know that I can manually enumerate the subkeys and iterate --export-ssh-key 'SUBKEY!' but that's really clunky. Besides, what I want to do is to tell people:
To get my SSH key, type the following:gpg --recv-keys 8DC901CE64146C048AD50FBB792152527B75921E # optional, do check validity gpg --export-ssh-key 8DC901CE64146C048AD50FBB792152527B75921E
Not a crazy shell script that's going to haphazardly parse --with-colons (and break in the next upgrade).
At least there should be an --export-option to tweak that.
Thanks for that nice feature!
