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 ...

Since 1982, STP has been defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of exactly 10 5 Pa (100 kPa, 1 bar ). NIST uses a temperature of 20 °C (293.15 K, 68 °F) and an absolute pressure of 1 atm (14.696 psi, 101.325 kPa). [ 3] This standard is also called normal temperature and pressure (abbreviated as NTP ).
