PGP

PGP Corporation was a company that specialized in encryption software and was responsible for creating PGP, which stands for Pretty Good Privacy. PGP was designed to secure email and online communications by encrypting messages using public-key cryptography.

The software used a combination of symmetric-key encryption and public-key cryptography to ensure the privacy and authenticity of messages. PGP was widely adopted by individuals, businesses, and government agencies as a way to protect sensitive information from unauthorized access.

PGP Corporation also offered other security tools, including full-disk encryption and managed file transfer products. The company was acquired by Symantec in 2010 and PGP remains a popular encryption tool.
