cryptanalysis

[‚krip·tə′nal·ə·səs]
(communications)
Steps and operations performed in converting encrypted messages into plain text without previous knowledge of the key employed.

cryptanalysis

The branch of cryptography concerned with decoding encrypted messages when you're not supposed to be able to.

cryptanalysis

The art of recovering original data (the plaintext) that has been encrypted (turned into ciphertext) without having access to the correct key used in the encryption process. When new encryption algorithms are introduced, cryptanalysis determines how hard it is to break the code. See encryption.
