Subject: keys are sometimes not removed from pgg's password cache
X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=failed
version=3.0.4
Keys, e.g. email addresses, that are longer than 16 characters will
not be properly removed from pgg's password cache.
You can verify this problem by evaluating the following expressions:
(require 'pgg)
(setq pgg-cache-passphrase t
pgg-passphrase-cache-expiry 4)
(pgg-add-passphrase-to-cache "xxxxxxxx123456789" "foo")
pgg-pending-timers
; -> [0 \123456789 0 0 0 0 0]
If you check pgg-pending-timers repeatedly you'll see that the timer
won't be removed and that the password can still be retrieved from the
cache after 4 seconds:
(pgg-read-passphrase-from-cache "xxxxxxxx123456789")
; -> "foo"
The key can be deleted manually though:
(pgg-remove-passphrase-from-cache "xxxxxxxx123456789")
According to pgg.el "keys are truncated to 8 trailing characters
unless NOTRUNCATE is true". But actually the macro
pgp-truncate-key-identifier in pgg-def.el doesn't truncate keys.
Instead the first eight characters are removed from the key:
(pgg-truncate-key-identifier "xxxxxxxx123456789")
; -> "123456789"
The macro is defined as follows:
(defmacro pgg-truncate-key-identifier (key)
`(if (> (length ,key) 8) (substring ,key 8) ,key))
I think the second argument to substring should be -8 instead
of 8:
(defmacro pgg-truncate-key-identifier (key)
`(if (> (length ,key) 8) (substring ,key -8) ,key))
I don't know why keys mustn't be longer than 8 characters. But the
fix above solved my problem.
Kind regards,
Andreas

I probably recalled the intent of that function; it is used to truncate
the long key ID (i.e. fingerprint) to the last 8 letters.
The above fix is reasonable. I just installed the following patch in
Gnus. Could someone install it to Emacs?

Done (installed in Gnus v5-10 and Emacs).
BTW, it's sufficient to install changes that should go into Gnus
trunk, Gnus 5.10.* (v5-10 branch) and Emacs CVS only in Gnus v5-10
branch. The arch magic (aka Miles Bader) will sync it (see
texi/gnus-coding.texi in Gnus trunk).
Bye, Reiner.
