The known-plaintext attack ( KPA ) is an attack model for cryptanalysis where the attacker has access to both the plaintext (called a crib ) and its encrypted version ( ciphertext ). These can be used to reveal secret keys and code books . The term "crib" originated at Bletchley Park , the British World War II decryption operation, where it was defined as:

When those words or phrases appeared, they would feed
