What kind of cryptography is used in PGP?
PGP uses asymmetric cryptography so it contains two keys – Private key used for digital signatures and decryption of incoming messages and Public key used for encryption and validation of digital signatures. Each PGP key features a unique Fingerprint consisting of a short string of numbers and letters.
