[Evolution] Security - PGP Sign and PGP Encrypt

[Thinker <thinker thoughtprogress com>]

Hello All,

I was browsing around looking at the different menus in Evolution and I
was wondering what the Security (PGP Sign and PGP Encrypt) is all about?
How do I go about implementing it?

I have noticed several emails stating that they are digitally signed. I
would like this capability.


Thanks,
