“The security of SHA-1 has been somewhat compromised by cryptography researchers.[1] Although no attacks have yet been reported on the SHA-2 variants, they are algorithmically similar to SHA-1 and so efforts are underway to develop improved alternative hashing algorithms.[2][3] An open competition for a new SHA-3 function was formally announced in the Federal Register on November 2, 2007.[4] “NIST is initiating an effort to develop one or more additional hash algorithms through a public competition, similar to the development process for the Advanced Encryption Standard (AES).”[5] Submissions are due October 31, 2008 and the proclamation of a winner and publication of the new standard are scheduled to take place in 2012.”
