Short description: none

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

Cyclic redundancy checks

Main page: 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.

Checksums

Main page: Checksum
Name Length Type
BSD checksum (Unix) 16 bits sum with circular rotation
SYSV checksum (Unix) 16 bits sum with circular rotation
sum8 8 bits sum
Internet Checksum 16 bits sum (ones' complement)
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
xor8 8 bits sum
Luhn algorithm 1 decimal digit sum
Verhoeff algorithm 1 decimal digit sum
Damm algorithm 1 decimal digit Quasigroup operation
