Hi,
Recently I have been trying to setup gnus to decrypt email, but
without too much success. I'm not sure whether this is a gnus or an
epa configuration issue, or a bug somewhere.
Here's my configuration:
(require 'epa)
(setq mml2015-use 'epg)
(setq mml2015-cache-passphrase nil)
(setq gnus-message-replysign t)
(setq gnus-message-replyencrypt t)
(setq gnus-message-replysignencrypted t)
(setq gnus-treat-x-pgp-sig t)
(setq mm-verify-option 'always)
(setq mm-decrypt-option 'always)
To test it, I've used mutt to send an encrypted email to myself.
I can successfully decrypt this email in mutt, but not on gnus. When
I access this email in summary buffer, I'm asked for a passphrase.
But then I get only this in the message buffer:
[[PGP Encrypted Part:Corrupted]]
[1. application/pgp-encrypted; signedkey.msg]...
[[End of PGP Encrypted Part]]
Any ideas/suggestions? What am I missing here?
Cheers,
--

Right, so I did a little bit more testing. Basically, I removed Ma
Gnus from my Emacs configuration and tried to decrypt the same email
with the Gnus version shipped with Emacs (24.1.50 from git, btw). And
guess what: it did work.
I'm a complete disaster with lisp, but would I'm available to try out
some suggestions on how to debug this.
Cheers,

I forgot to refer the different behaviour between the 2 Gnus versions:
- Gnus shipped with Emacs:
I select the email (summary buffer) and I get the question "Decrypt
(PGP) part? (y or n)". When I answer 'y', I'm asked for the
passphrase and get the email decrypted
- Ma Gnus:
I get the same question ("Decrypt (PGP) part? (y or n)") and when I
reply 'y', I get another question: "Decrypt pgp encrypted part? (y
or n)". Only after answering 'y' to this question I'm asked for the
passphrase.

Can't reproduce it with either Gnus shipped with Emacs (bzr trunk) nor Ma
Gnus (git master).

FWIW, try (info "(epa) Bug Reports"). And if possible, send me an email
encrypted with mutt (my key ID is D7E69871).

Interesting, so it has to be my configuration. Any chances of sharing
the relevant parts of your configuration?

I've sent you (privately) an encrypted email.

Thanks, I could reproduce it. It seems indeed to be caused by the
recent changes to Ma Gnus:

Subject: [PATCH] mm-decode: don't touch MIME type for multipart/encrypted
children
The commit 1bf64efe introduced auto detection of actual MIME types
for application/octet-stream. That changes the MIME type of
encrypted part to "text/plain" when it has filename parameter with
".asc", and causes decryption failure.

Great, thanks a lot! I confirm this has solved the problem -- I am
now able to successfully decrypt emails with this patch applied.
