PGP Encryption (Pretty Good Privacy) is a computer program that provides cryptographic privacy and authentication. It is based on asymetric encryption (one public key + one private key) and was originally created by Philip Zimmermann in 1991. Shortly after its release, PGP encryption found its way outside the US, and in February 1993 Zimmermann became the formal target of a criminal investigation by the US Government for violating the export regulations. Since the end of the 90's, PGP encryption no longer meets the definition of a non-exportable weapon and can be exported internationally except to 7 specific countries.PGP and other similar products follow the OpenPGP standard for encrypting and decrypting data. To encrypt your messages, we advise you to use either GnuPG (for MacOS and Linux) or WinPT (for Windows).
