PGP/GPG Keys in Ubuntu Gnome the easy way – Part 2

In part 1, I explained how to generate and manage your encryption keys in GNOME. Now I’ll explain how to use your keys to easily encrypt your email. I’m going to only address doing this in Evolution (the default email manager in GNOME). You can access the Evolution email account settings by going to System > Preferences > Email settings [Natty/Unity: System Settings > Email], and I’ll assume that Evolution is already set up for your email account.

Integration into Evolution is painlessly simple: You just need the Key ID of your key.

Go to System > Preferences > Passwords and Encryption Keys and look in the column under Key ID. The Key ID is hex, so it only uses the characters 0-9 and A-F.

Once you have the Key ID, start Evolution and go to Edit > Preferences > Mail Accounts and click your mail account and click edit. Then, go to the Security tab and enter your Key ID in the PGP/GPG Key ID field.

That’s it. Now whenever you compose a message, you’ll see the PGP menu which will allow you to sign and/or encrypt your email messages, and in the reading pane you will see the status of signed/encrypted messages sent to you.

Questions, comments, and feedback to this are welcome, as always.
