Question Ranking
Pros

The original version of PGP is no longer freeware since it was aquired by Symantec, but the source code can still be downloaded for peer review.

PGP uses asymmetric encryption. One user generates 2 keys - private and public. Another user uses the public key to encrypt the message that can then be decrypted only using first users's private key.
