Md5 birthday attack

WebFor a 64-byte block hash such as HMAC-MD5-96, an attack involving the successful processing of 2**64 blocks would be infeasible unless it were discovered that the underlying hash had collisions after processing 2**30 blocks. A hash with such weak collision-resistance characteristics would generally be considered to be unusable.
