[unimpressive]

>Until the tools take 5 min to setup, and encryption/decryption is automatically handled by the mail client, PGP will never take off. Things like the public key directory have to handled transparently to the user.

Actually, we're close to that. I have had trouble figuring out how to smoothly encrypt attachments though. (I'm sure it can be done though.)

Five minutes to set up? Yeah pretty much.

Encryption/decryption of emails is handled automatically in enigmail after the first encrypted email is sent. You can set it up so that for certain users it sends them an encrypted message by default. (Though the interface for this is a little confusing, it could use some polish.)

It helps you import a key if a fingerprint is included or a public key attached to the email.

I was actually pretty impressed with what I didn't have to do. It still needs some improvement though.
