ISO/IEC 10118-3:2003 specifies dedicated hash-functions, i.e., specially designed hash-functions. The hash-functions in ISO/IEC 10118-3:2003 are based on the iterative use of a round-function.
ISO/IEC 10118-3:2003 specifies seven distinct round-functions, giving rise to distinct dedicated hash-functions. In particular:
- the first hash-function (RIPEMD-160) in Clause 7 of ISO/IEC 10118-3:2003 provides hash-codes of lengths up to 160 bits;
- the second hash-function (RIPEMD-128) in Clause 8 of ISO/IEC 10118-3:2003 provides hash-codes of lengths up to 128 bits;
- the third hash-function (SHA-1) in Clause 9 of ISO/IEC 10118-3:2003 provides hash-codes of lengths up to 160 bits;
- the fourth hash-function (SHA-256) in Clause 10 of ISO/IEC 10118-3:2003 provides hash-codes of lengths up to 256 bits;
- the fifth hash-function (SHA-512) in Clause 11 of ISO/IEC 10118-3:2003 provides hash-codes of lengths up to 512 bits;
- the sixth hash-function (SHA-384) in Clause 12 of ISO/IEC 10118-3:2003 provides hash-codes of a fixed length, 384 bits; and
- the seventh hash-function (WHIRLPOOL) in Clause 13 of ISO/IEC 10118-3:2003 provides hash-codes of lengths up to 512 bits.
For each of these seven dedicated hash-functions, ISO/IEC 10118-3:2003 specifies a padding method, initializing values, parameters, a sequence of functions (which are used in the round-function), constants, and an object identifier; and provides several computation examples.
