FORK-256

FORK-256

FORK-256 is a proposed hash algorithm to withstand security holes that were found in SHA-1 and MD5. The algorithm was designed to be more secure and also faster than SHA-256. FORK-256 uses 512-bit blocks and implements preset constants that change after each repetition. Each block is hashed into a 256-bit block through four branches that devides each 215 block into sixteen 32-bit words that are further encrypted and rearranged. Because the four branches are used in parallel, where as SHA-256 uses four serial rounds, FORK-256 is hard to analyze. It hasn't made it much beyond testing.
