List of hash functions

Cyclic redundancy checks

Main article: Cyclic redundancy check

Name	Length	Type
BSD checksum	16 bits	CRC
checksum	32 bits	CRC
crc16	16 bits	CRC
crc32	32 bits	CRC
crc32 mpeg2	32 bits	CRC
crc64	64 bits	CRC
SYSV checksum	16 bits	CRC

Adler-32 is often classified as a CRC, but it uses a different algorithm.
