You're worried about the attack where someone generates a set of features that has the same hash as the a different set of features. In this case, the birthday attack doesn't help, since you only get to pick one set of ciphertext.

I really don't care what algorithm we pick. They will likely all be cracked one day. Please pick one that emits a relatively small hash, though, please.

Why md5, which has been proven to be insecure? SHA1 would be just as easy to implement, and is much better in this regard.
