Cryptography crib
http://facweb1.redlands.edu/fac/Tamara_Veenstra/cryptobook/loops.html WebA crib is a portion of ciphertext which is known or assumed to be an encryption of a specific phrase of plaintext. It is a very useful technique to use in cryptanalysis, and was fundamental to the breaking of many ciphers in periods of war. ... An idea in cryptography that all codes and ciphers aim for, perfect secrecy means that the cipher is ...
