Verifying articles signed in headers

Verifying articles signed in headers

[Christopher Splinter]

Hi,

Is it possible to verify messages signed in the head, _not_ in
the body?

This is the way control messages in de.* are signed and I'd like
to be able to verify them.

Is there any document about this kind of signature?  Any example (I
don't have any de.* group in my news server)?

No one that I'm aware of.

Thanks for the info.

I've implemented it. It works as article treatment.  The switch
variable is gnus-treat-x-pgp-sig.  The function is bound to `W p'.  To
see the result, you should make "X-Gnus-PGP-Verify" visible (see
`gnus-visible-headers').

I'll add the document a few days later.
