On Oct. 31-Nov. 1, 2005, 180 members of the global cryptographic community gathered in Gaithersburg, Maryland to attend the first Cryptographic Hash Workshop. The workshop was organized in response to a recent attack on the NIST-approved Secure Hash Algorithm SHA-1. The purpose of the workshop was to discuss this attack, assess the status of other NIST-approved hash algorithms, and discuss possible near-and long-term options.
