JH: Information from Answers.com

JH is a cryptographic hash function submitted to the NIST hash function competition by Hongjun Wu. JH has a 1024-bit state; after padding the message is broken into 512-bit blocks, each of which is XORred into the state twice once before application of a 36-round unkeyed permutation and once afterwards. It is well suited to a bit slicing implementation using the SSE2 instruction set, giving speeds of 16.8 clocks/byte.
