WebWhirlpool is a hash designed after the Square block cipher, and is considered to be in that family of block cipher functions. Whirlpool is a Miyaguchi-Preneel construction based on a substantially modified Advanced Encryption Standard (AES). Whirlpool takes a message of any length less than 2 256 bits and returns a 512-bit message digest. [3] WebWhirlpool is a Miyaguchi-Preneel construction based on a substantially modified Advanced Encryption Standard (AES). It takes a message of any length less than 2 256 bits and returns a 512-bit message digest. The authors have declared that "WHIRLPOOL is not (and will never be) patented. It may be used free of charge for any purpose."
