+==============================
 
 caff is a script that helps you in keysigning.  It takes a list of
 keyids on the command line, fetches them from a keyserver and calls
 GnuPG so that you can sign it.  It then mails each key to all its
 email addresses - only including the one UID that we send to in each
-mail.
+mail, pruned from all but self sigs and sigs done by you.  The mailed
+key is encrypted with itself as a means to verify that key belongs to
+the recipient.
 
+Since we do not upload the new signatures, or import them into our
+main keyring, the signature only gets public if:
+ - the email address is valid, and
+ - the person reading the email can decrypt the mail (if it was sent
+   encrypted).
+Therefore we achieve the same level of security as common Challenge
+Response systems like CABot, without all the extra hassle of those
+systems.
