Well, this is a fundamentally insecure way of using *any* crypto hash method.
You're blaming MD5 for the fact that you're misusing it.
There has to be some component of the hash input that the attacker
doesn't know and can't trivially guess. Adding a randomly chosen "salt"
string is one common way to do that.
