I'm afraid I'm totally confused. I come from a PGP-on-Windows background. In Ubuntu, I notice that Seahorse is already installed.
- I imported my PGP keys into Seahorse successfully.
- However, now I have no clue how to use the keys! Someone sends me an encrypted email; how do I decipher it? And how do I encrypt an email back to that person?
- In Seahorse, I chose menu options Key -> Back up Key Rings... It saved the key rings as a zip file. How do I restore the key rings (for example if I move to another computer)?
