ITT we discuss web security.
An NVIDIA GeForce 8800 Ultra can calculate more than 200 million hashes per second.[19]
MD5 uses the Merkle–Damgård construction, so if two prefixes with the same hash can be constructed, a common suffix can be added to both to make the collision more likely to be accepted as valid data by the application using it. Furthermore, current collision-finding techniques allow to specify an arbitrary prefix: an attacker can create two colliding files that both begin with the same content.
