CSA ISO/IEC 10118-3:04 (R2019)

Scope

This part of ISO/IEC 10118 specifies dedicated hash-functions, i.e. specially designed hash-functions. The hash-functions in this part of ISO/IEC 10118 are based on the iterative use of a round-function. Seven distinct round-functions are specified, giving rise to distinct dedicated hash-functions.

The first and third dedicated hash-functions in Clauses 7 and 9 respectively provide hash-codes of lengths up to 160 bits; the second in Clause 8 provides hash-codes of lengths up to 128 bits; the fourth in Clause 10 provides hash-codes of lengths up to 256 bits; the sixth in Clause 12 provides hash-codes of a fixed length, 384 bits; and the fifth and seventh in Clauses 11 and 13 respectively provide hash-codes of lengths up to 512 bits.
