Uh. All of the current SHA-3 candidates are as fast or faster than SHA-1. That's one of the contest's design goals:<p><i>NIST expects SHA–3 to have a security strength that is at least as good as the hash algorithms currently specified in FIPS 180–2, and that this security strength will be achieved with significantly improved efficiency.</i><p><a href="http://csrc.nist.gov/groups/ST/hash/documents/FR_Notice_Nov07.pdf" rel="nofollow">http://csrc.nist.gov/groups/ST/hash/documents/FR_Notice_Nov0...</a>
