Whirlpool (hash function)

In computer science and cryptography, Whirlpool is a cryptographic hash function. It was designed by Vincent Rijmen and Paulo S. L. M. Barreto, who first described it in 2000. It is named after the Whirlpool galaxy in Canes Venatici, the first one recognized to have a spiral structure by William Parsons, third Earl of Rosse, in April 1845.
