H(Salt . H(Password)) is a lot like an hmac (minus the secret part and the padding). I'm not sure about the pre-image vulnerability mentioned on wikipedia's md5 page, but as for collision vulnerabilities, according to wikipedia's hmac page, "HMACs are substantially less affected by collisions than their underlying hashing algorithms alone. Therefore, HMAC-MD5 does not suffer from the same weaknesses that have been found in MD5." |
