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

“Scandal is an importunate wasp, against which we must make no movement unless we are quite sure that we can kill it; otherwise it will return to the attack more furious than ever.”
