decrypting S/MIME messages

[Vladimir Volovich <vvv@vsu.ru>]

Hi!

when i receive an encrypted S/MIME message, gnus diaplays something
like

  From: someone@somewhere
  Subject: something
  To: Vladimir Volovich <vvv@vsu.ru>
  Date: Fri, 27 Jul 2001 20:01:57 +0400

  [1. S/MIME Encrypted Message --- application/x-pkcs7-mime; smime.p7m]...

and when i press on the button, gnus proposes to save the
base64-encoded encrypted message body into a file! (instead of
proposing to decrypt the message).

If i raw-preview the message (C-u g), copy all the contents into some
buffer, and call M-x smime-decrypt-buffer, i see the decrypted message
body just fine, but of course non-formatted.

or, if i save the raw message in a file, and run
openssl smime -decrypt -recip /home/noc/vvv/.certs/vvv-cert.pem < message.txt
i also see the correctly decryptes message.

The question is: how should i view encrypted s/mime messages? why
there are no calls to smime-decrypt-buffer done by gnus automatically?

Is it just not-yet-implemented, but all framework is there already?

Best,
v.
