Encryption, can I plug in PGP to evolution

Evolution (at least the latest versions) has PGP/GPG support built in.

Edit > Preferences > Mail Accounts > Edit > Security

Also, in each message you compose there is a "Security" option on the toolbar that allows you to sign/encrypt a message. You'll have to have a keypair generated already in your home directory.

Thanks very much for the good news about pgp being available. I still have a problem concerning setting up evolution. I have gpg working on my imported keys. The files I have are the usual me.asc pubring-bak.pkr pubring.pkr secring-bak.skr secring.skr. And gpg imorted everything just fine. So now in preferences->bla I am asked to supply my PGP/GPG Key ID, well I tried the lot and get this message when I try to sen a signed mail ...

ould not create message.

Because "gpg: skipped "/home/julian/pgp/keys/me.asc": secret key not available
gpg: signing failed: secret key not available
", you may need to select different mail options.

So what am i supposed to enter in this field ?? And naturally the other two "certificate" fields.
Thanks a lot for the help so far, grovel grovel

I use terminal, hopefully you do as well :)

gpg --list-keys

make sure your key is listed there.

gpg --edit-key <user id>

gpg will show a message like "Secret Key is Available"

If it doesnt, well, it means your secret key wasnt imported which is what it seems the error message is indicating.
