List of hash functions This is a list of hash functions, including cyclic redundancy checks, checksum functions, and cryptographic hash functions. This list is incomplete; you can help by adding missing items. (February 2024) Cyclic redundancy checks Main article: Cyclic redundancy check Name Length Type cksum (Unix) 32 bits CRC with length appended CRC-8 8 bits CRC CRC-16 16 bits CRC CRC-32 32 bits CRC CRC-64 64 bits CRC Adler-32 is often mistaken for a CRC, but it is not: it is a checksum.
