HAS-160 is a cryptographic hash function designed for use with the Korean KCDSA digital signature algorithm. It derives from SHA-1, with assorted changes that supposedly increase its security. It produces 160 bit output.
HAS-160 is used in the same way as SHA-1. First it padds the input and divides it in blocks of 512 bit each. A digest function updates the intermediate hash by processing the input blocks in turn.
The message digest consists of 80 rounds.
