What is gnome-keysign

gnome-keysign is:

GNOME Keysign is a tool for signing OpenPGP keys.

Its purpose is to ease signing other peoples’ keys. It is similar to caff, PIUS, or monkeysign. In fact, it is influenced a lot by these tools and either reimplements ideas or reuses code. Consider either of the above mentioned tools when you need a much more mature codebase.

In contrast to caff or monkeysign, this tool enables you to sign a key without contacting a key server. It downloads an authenticated copy of the key from the other party. For now, the key is authenticated by its fingerprint which is securely transferred via a QR code. Alternatively, the user may type the fingerprint manually, assuming that it has been transferred securely via the audible channel.

After having obtained an authentic copy of the key, its UIDs are signed. The signatures are then encrypted and sent via email. In contrast to monkeysign, xdg-email is used to pop up a pre-filled email composer windows of the mail client the user has configured to use. This greatly reduces complexity as no SMTP configuration needs to be obtained and gives the user a well known interface.
