The analysis and deciphering of cryptographic writings or systems.
The study of techniques for deciphering cryptographic writings or systems.
The act or science of deciphering a code or coded message without a prior knowledge of the key.
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.
An analysis or decrypting of a specific text or a specific code or cipher.
