I wrote a couple more User Defined Functions for MySQL today, this time adding support for Whirlpool and Tiger, respecivey 512bit and 192 bit hash functions. More details are available at www.kfwebs.net

WHIRLPOOL is a hash function designed by Vincent Rijmen and Paulo S. L. M. Barreto that operates on messages less than 2^256 bits in length, and produces a message digest of 512 bits.

WHIRLPOOL has been selected for the NESSIE portfolio of cryptographic primitives. The International Organization for Standardization (ISO) has decided to include the final version of WHIRLPOOL in the revised ISO/IEC 10118-3:2003(E) standard.

Tiger is a cryptographic hash function designed by Ross Anderson and Eli Biham in 1996 with a view for efficiency on 64-bit platforms. The size of a Tiger hash value is 192 bits. There also exists 128 and 160-bit versions of this algorithm, called Tiger/128 and Tiger/160. Both variants return truncated Tiger/192 hash values.
