This part of ISO/IEC 10118 specifies hash-functions which make use of an n-bit block cipher algorithm. They are therefore suitable for an environment in which such an algorithm is already implemented. Four hash-functions are specified. The first provides hash-codes of length smaller than or equal to n, where n is the block-length of the algorithm used. The second provides hash-codes of length less than or equal to 2n; the third provides hash-codes of length equal to 2n; and the fourth provides hash-codes of length 3n. All four of the hash-functions specifide in this part of ISO/IEC 10118 conform to the general model specified in ISO/IEC 10118-1.
