Avalanche - a measure of how the output bits change based on each input bit. Ideally each input bit will affect each output bit with 1/2 probability.
Realistically, many hash functions do not achieve perfect avalanche and are still useable for many sets of keys.
Cipher - an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure.
This is a list of hash functions, including cyclic redundancy checks, checksum functions, and cryptographic hash functions.
For each function are included: description, implementations and materials.
A cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to raw data.
A checksum or hash sum is a small-size datum from an arbitrary block of digital data for the purpose of detecting errors which may have been introduced during its transmission or storage.
A cryptographic hash function is a hash function which is considered practically impossible to invert, that is, to recreate the input data from its hash value alone.
A cryptographic hash function is a hash function which is considered practically impossible to invert, that is, to recreate the input data from its hash value alone.
