True. MD5 is a one way hash routine. It does, however, produce reproducable results. It would be good for storing passwords in a database, for example. > > What you have to do is compare a value that you submit with the MD5 > hash, meaning it is possible to have 2 entirely different values match > the hash. This is extremely unlikely. It is like having 2 completely different files result in an identical CRC check value. Since the MD5 hash returns a 128 bit digest (hash) of whatever you are encoding, it is very unlikely to produce the same digest for different sources.
