List of hash functions

This is a list of hash functions, including cyclic redundancy checks, checksum functions, and cryptographic 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.

sum8	8 bits	sum
sum16	16 bits	sum
sum24	24 bits	sum
sum32	32 bits	sum
fletcher-4	4 bits	sum
fletcher-8	8 bits	sum
fletcher-16	16 bits	sum
fletcher-32	32 bits	sum
Adler-32	32 bits	sum
