The NSRL staff have received questions about the announcement of a SHA-0 collision at the CRYPTO 2004 conference, as well as other collisions. NIST staff from the Computer Security Division were in attendance, and the statements here are meant to reflect the ramifications of the announcement on the NSRL, not on general cryptography nor on hashing applications elsewhere. One of the NIST attendees has communicated to the NSRL project that “nothing presented at Crypto 2004 indicated that SHA-1 has been broken.”
