FORK-256 FORK-256 is a hash algorithm designed in response to security issues discovered in the earlier SHA-1 and MD5 algorithms. After substantial cryptanalysis, the algorithm is considered broken. ==Background== In 2005, Xiaoyun Wang announced an order- collision attack on the government's hash standard SHA-1.〔〔 The National Institute of Standards and Technology (NIST), the body responsible for setting cryptographic standards in the United States, concluded this was a practical attack (as previous estimates were order-) and began encouraging additional research into hash functions and their weaknesses.〔 As part of this effort, NIST hosted two workshops where potential new algorithms, including FORK-256, were introduced and discussed.〔 Rather than immediately select any of these algorithms, NIST conducted a public competition from 2007–2012 which ultimately resulted in the Keccak algorithm being selected for use as the SHA-3 standard.〔
