Pretty Good Privacy (PGP) is an encryption and decryption program developed by Phil Zimmermann in 1991 that ensures e-mail security through a combination of algorithms. PGP provides cryptographic privacy and authentication for various forms of data communication, including signing and encrypting texts and files. Its key features include authenticity, integrity, non-repudiation, and confidentiality, utilizing technologies like hashing, public key cryptography, and digital signatures.
