The GnuPG article talks about ease of use being the primary concern as users move from PGP to the free GnuPG. I would whole-heartedly agree. I wouldn’t think of using GnuPG if I didn’t have simple tools to use it with. Since I use Mailcrypt, I don’t have to worry about arcane commands and extra steps to use encryption. Just select a menu item or hit a couple of keys and the mail is encrypted or signed.
