Gnus/Mailcrypt and MIME charset

Gnus/Mailcrypt and MIME charset

[Markus Hilpert]

Hello,

using Gnus (gnus-verison "No Gnus v0.6") and Mailcrypt, I always end up
with a header stating "charset=us-ascii" for encrypted messages. I
presume, the message is first encrypted and then MIME encoded. This
causes confusion with some mailreaders of my messages' recipients when
using non-ASCII-characters.

Is it possible to have the message MIME encoded before encryption? When
using vm, I do something in the line of

(add-hook 'mc-pre-encryption-hook '(lambda ()
          (if (not (vm-mail-mode-get-header-contents "MIME-Version:"))
          (vm-mime-encode-composition))))

What would be the canonical way for Gnus? Maybe I did not search very
intelligently, but I did not find an answer. Maybe I was putting the
wrong question?

Thanks for hints!
Markus

Forget about Mailcrypt, use encryption built into Gnus.  And if you
encrypt non-ACSII text, use PGP/MIME (this is a name of standard that
Gnus support) instead plain PGP data.  Depending on recepient's
software, he may need to install some extantion (Enigmail for
Thunderbird, for example) for more convenient handling of PGP/MIME.

See (info "(message)Security").

Hello,

actually, I had tried the mml-functions in order to generate PGP/MIME
conforming messages, but the resulting MIME format was unusable for a
recipient using pine.

Gnus seems to always convert the charset header of my encrypted
messages to us-ascii, but my recipients that use non-ascii characters
have confirmed that the messages are Ok after decryption.

May be it's worth trying pgg + gpg ?
