What is a PGP?

PGP stands for Pretty Good Privacy, which is an encryption program used to secure emails, files, and other forms of digital communication. PGP uses a combination of public key and symmetric key cryptography to ensure that messages are kept private and can only be read by the intended recipient. It is widely used by individuals and organizations to protect sensitive information from unauthorized access. PGP is available as both free and commercial software and is considered a standard for secure communication.
