I have two questions connected with encryption:
1. How to verify a signature without Gnus?
Some of my friends use web interfaces to read email. Can they verify my
PGPMIME signature?
I assume that they should download raw message, save a part of it to a
file, then verify signature using that file.
Is it right? Which part of a raw message should be saved?
2. Can I encrypt an attachment with Gnus?
I've noticed that Gnus only encrypts the body. Can it encrypt
attachments? (I'm using PGPMIME).

One way is to simply use gpg from the command line:
$ gpg --verify signature.asc content.part
If you are using Thunderbird, you can install the Enigmail extension to
handle signatures (and other PGP-stuff).

I think that depends on whether the web interfaces they use support that
functionality?

That would be a way. A very cumbersome way :-)

The part that is signed, and the signature.

Sure.
When you have attached a file, you can either manually change the
"
[-- Attachment #2: Type: text/plain, Size: 504 bytes --]
"-tag to include "encrypt=pgpmime", or you can simply choose
"Encrypt part" from the "Attachments" menu.
I just tested against Thunderbird with Enigmail, and it just ignores the
encrypted attachment, so I guess it depends on the client how well it is
handled - MIME can be tricky (Gnus seems to handle it fine, though).
Best regards,
Adam

Ugh. That should have read: 'change the "< # part>"-tag' (without the
spaces). Sorry.
