![]() ![]() Today, it is used to encrypt and decrypt text messages and email. Pretty Good Privacy, also known as PGP, was originally created by Phil Zimmerman in 1991 as a way for people to communicate without eavesdropping. All three standards are in use today, but have different applications. They are similar in that OpenPGP is an open alternative to PGP (we will get into why later), and GnuPG is based off of the OpenPGP standard. In this article, we are going to discuss three popular forms of encryption called PGP (Pretty Good Privacy), OpenPGP, and GnuPG (GNU Privacy Guard). Of course, the encryption algorithms today are far superior with the help of advanced mathematics and computers, thus making brute force attacks much harder to pull off. However, the fundamentals of encryption today are much the same as they were in the ciphers of the past. Nowadays, encryption is necessary to ensure that no one is listening in on our conversations and to keep would-be criminal actors from stealing or corrupting that data. The story goes that two people who needed to communicate securely over long distances could with the cipher. Not even the messenger would know what a message meant without the proper decoder rings. The cipher is considered one of the earliest forms of encryption and was used in Ancient Rome to keep information secret. ![]() It’s so important to us in our every day lives and yet it has one of the longest and confusing pasts of any type of technology we use today.Įncryption has been used since ancient times by generals, spies, rebels, and even politicians. ![]()
