OpenPGP: Up until 1992, cryptography featured on the US Munitions List as an Auxiliary Military Equipment. Now owned by Symantec but licensed by thousands of companies. PGP: Developed by Phil Zimmerman in 1991, PGP is one of the most enduring digital encryption methods and the most popular email encryption tool. Here's a quick history of PGP, OpenPGP, and GPG. Unless you're going to be buying a PGP-enabled product from Symantec, the company that currently owns the PGP copyright and company, you'll likely be using GPG. GPG is an open-source implementation of PGP, and works on the same principles. Throughout this article, I'll be discussing both PGP and Gnu Privacy Guard (GnuPG, or GPG).

In addition to encryption, PGP also allows for digital signatures. But it's also quite safe, as messages can only be decrypted with privately known keys that are password-protected. This system ensures that it's easy to send encrypted communications because the only thing needed to encrypt a message is a public key and the proper PGP program. It'll help make encryption terminology much easier to understand. Unsure what a public key or a private key is? Check out these basic encryption terms before reading on. It works by encrypting a message using a public key that's tied to a specific user when that user receives the message, they use a private key that's known only to them to decrypt it. PGP stands for "Pretty Good Privacy." PGP is most often used for sending encrypted messages between two people.
