Difficulties using EasyPG in gnus

Difficulties using EasyPG in gnus

[Elias Oltmanns]

Hi all, hi Daiki Ueno in particular,

as stated in the subject line I have some difficulties to get EasyPG
and gnus working together. Specifically, the problem I encounter is
the following:

Since I use multiple email addresses, I added the following to my
message-send-hook:
  (setq pgg-default-user-id (message-field-value "From"))

With EasyPG, however, pgg-default-user-id doesn't seem to have any
effect at all. On the contrary, it seems that always the first
private key available in the key ring is chosen.

Additionally, I noticed that epg-user-id-alist only contains this very
first identity, so I'm wondering how to make epg aware of my other
private keys and use them appropriately.

Kind regards,

Elias

Sorry, I've forgotten to add the whole lot of supplementary
information:

No Gnus v0.6 + EasyPG 0.0.3
In my emacs startup files:
(require 'epa-setup)
...
(setq pgg-scheme 'epg)
(require pgg)
...

Of course, pgg-epg.elc is in the load path.

Kind regards,

Elias

This is a bug of pgg-epg.el.  I fixed it as follows.

Thanks, that worked.
