WebCryptanalysis of single-key cryptosystems (described in the section Cryptography: Key cryptosystems) depends on one simple fact—namely, that traces of structure or pattern in the plaintext may survive encryption and be discernible in the ciphertext. WebA cryptographic hash function is a deterministic procedure that takes an arbitrary block of data and returns a fixed-size bit string, the ( cryptographic) hash value, such that an accidental or intentional change to the data will change the hash value. razer x a bathing ape
