Pretty Good Privacy (PGP) Key

Pretty Good Privacy (PGP) is a popular method of encryption for online communications. Using PGP, a message is converted to unreadable and encrypted text (ciphertext). Only the message recipient has the PGP key, which allows the message to be converted back into readable text (plaintext). PGP is thought to be very secure and private because it employs both symmetric and public-key cryptography (PKC).
