Gnus not recognizing encrypted message

Gnus not recognizing encrypted message

[Lloyd Zusman]

Normally, if someone sends me an encrypted message, Gnus recognizes the
fact when I try to read the message, and it prompts me, asking me if I
want to decrypt it.  If so, I get prompted for my passphrase and if the
message was properly encrypted with my public key, I can then read it.

However, today I received an encrypted message, and Gnus didn't
recognize it as being something to decrypt.

The message arrived as a single-part multipart/mixed message, with both
the encrypted message and the user's public key that part.

If I copy that part to a separate file and run `pgg-decrypt' on it, I
get prompted for my passphrase, and it decrypts with no trouble.  So I
know that the encryption block itself is OK.

Here's the structure of the information inside of that single part
of the multipart/mixed message:

  -----BEGIN PGP MESSAGE-----
  Version: MailVault 2.2 from MailVault Corporation  http://www.mailvault.com

  ... base 64 stuff ...

  -----END PGP MESSAGE-----


  PGP Public Key for Sender <sender@sendingdomain.tld>:

  -----BEGIN PGP PUBLIC KEY BLOCK-----
  Version: MailVault 2.2 from MailVault Corporation http://www.mailvault.com

  ... more base 64 stuff ...

  -----END PGP PUBLIC KEY BLOCK----

Could it be that Gnus doesn't recognize this block because it's within a
part of a multipart/mixed message?  Or perhaps could the extra public
key block be confusing things?

Whatever the case, is there a way to set up Gnus so that it recognizes
the encrypted message within the message part and then runs me through
the standard decryption dialog?

Thanks in advance.

Unfortunately Gnus doesn't detect inline PGP in already parsed parts, such
as a MIME part within a multipart/mixed.  The inline PGP code is only run
if there are is only one top-level text part.

Thank you.  Well, I figured out that I can run `gnus-display-mime' from
the Summary buffer in order to trigger the decryption dialog for
messages like these.  That's better than nothing.

But is there some sort of part-parsing hook that I can write, which
could trigger the inline PGP code for each appropriate part?

I don't think so, but you could defadvice `gnus-mm-display-part', I
guess...
