Please describe the problem:
I am a PGP user and I use SHA-512 as my default OpenPGP message digest (hash)..
it's also set in my key preferences. Using Evolution, I get the hash type
force-set to SHA-1 every time I send a mail. I looked at the source code just
now, and I see that it enforces SHA-1 instead of using the GnuPG defaults.
Patches will be attached here against my Fedora Core 4 Evolution SRPMS
(evolution-2.2.3-2.fc4 and evolution-data-server-1.2.3-3.fc4) to fix this
behaviour and also introduce SHA256, SHA384 and SHA512 message digests which
GnuPG 1.4.x stable supports.

Steps to reproduce:
1. Create a new keypair with the default hash preference as SHA512
2. Try sending mails with it
3. Check if SHA512 is really used


Actual results:
SHA-1 is used and the key preferences are overriden

Expected results:
The key preferences and/or the GPG preferences should be used by default unless
specified otherwise in Evolution's user-configuration

Does this happen every time?
Yes

Patches will be attached to this bug.
