Why is MD5 not cryptographically secure?

Solution

MD5 is considered insecure while using it in certain places like when we consider it for password then its not considered a good idea as MD5 approach is very fast and this gives attacker chances to try billions of passwords per second on single GPU.Take another scenario of file intergrity, but this depends upon how we use it.As MD5 are collision attacks and attacker can produce same hash function for tow different files but it cannot produce/match same hash function for existing file over which it has no control or influence.
