PGP, or Pretty Good Privacy, is a system that uses public/private keys as a means for encryption and message verification via signatures. By using the public key of your recipient, you can encrypt a message (or file) so that only the intended receiver can read the message. Also, by using your own private key, you can create a signature that cannot be faked, which serves as a means of authenticating a message and detecting forged messages.

A 30-day trial version can be found here:

After 30 days, Trial Software reverts to the functionality available in what used to be called PGP Freeware, or you can simply not enter the trial code and use the freeware functionality from the beginning.
