MD2, 4, and 5 all create 128-bit hashes MD6 can create up to 512-bit hashes MD2 was published in 1989 and was optimized for 8-bit machines. MD4 and 5 were published in 1990 and 1992, respectively, and were optimized for 32-bit machines. MD6 was published in 2008. WebHashing. Cryptographic hashes are functions that take some arbitrary input and return a fixed-length value. The particular value depends on the given hash algorithm in use, such as SHA-1 (used by git), SHA-256, or BLAKE2, but a given hash algorithm always returns the same value for a given input.
