MD5 generates a hash of 128 bits so the probability of finding a collision is 1/(2^128). So it seems that it is not so easy to find such a collision. Of course SHA is more secure, it generates a hash of 160 bits so the probability of finding a collision is lower than MD5. -- Sergio Rodr?guez de Guzm?n Mart?nez| Hombre anciano, juicio sano.
