The acronym PGP stands for Pretty Good Privacy. It is a data encryption and decryption program primarily used for securing email communication and data security. PGP employs a combination of symmetric-key cryptography and public-key cryptography, making it a versatile tool for users who wish to ensure the confidentiality and integrity of their messages.

PGP is notable for its strong encryption standards, allowing users to effectively protect their communications from unauthorized access while still enabling secure key sharing practices.
