The Basics of Cryptography 20 An Introduction to Cryptography. Then PGP uses the digest and the private key to create the signature. PGP transmits the signature and the plaintext together. Upon receipt of the message, the recipient uses PGP to recompute the digest, thus verifying the signature. An Introduction to Cryptography 15 The Basics of Cryptography. Public key cryptography is an asymmetric scheme that uses a pair of keys for encryption: a public key, which encrypts data, and a corresponding private key. (secret key) for decryption.an introduction to cryptography and cryptanalysis edward schaefer The Basics of Cryptography 28 An Introduction to Cryptography. PGP uses a passphrase to encrypt your private key on your machine. Your private key is encrypted on your disk using a hash of your passphrase as the secret key. You use the passphrase to decrypt and use your private key.
