== GPG Challenge ==

[source:keysigning/gpg-challenge.pl gpg-challenge.pl] is a script to send challenge emails for a challenge-response method of verifying UIDs on OpenPGP keys. It finds all UIDs that are valid and have not already been signed by the user for the key IDs given on the command-line, and generates email bodies containing some random data. These are passed onto [http://www.mutt.org/ the Mutt email client], where they should be signed, encrypted and sent to the signee. The signee should then reply to the email, keeping the random data intact.

gpg-challenge.pl is based on code that Ingo Klöcker [http://lists.gnupg.org/pipermail/gnupg-users/2006-July/028959.html posted] ([http://marc.info/?l=gnupg-users&m=115230269710683&w=2 archive at marc.info]) to the [http://lists.gnupg.org/mailman/listinfo/gnupg-users gnupg-users] mailing list.
