• PGP Freeware for non-commercial use
• PGP for Personal Privacy. This costs money and is licensed for business/commercial use.

On a technical level, any version of PGP with a version number of 5 or higher should be fine. Check descriptions of files - source code is available, you don't need that and it's much larger.
