comment Best way to reduce chance of hash collisions: Multiple hashes, or larger hash?
Thomas: you switched from SHA-256 in your answer to MD5 at the end. As you know, these are two different animals (neither animal, being a gorilla) since MD5 outputs only 128 bits and it has known collisions. Finding a collision by brute force (a suddenly very apt term in the present context) for a 128 bit hash is going to take "only" $2^{64}$ expected trials, making it roughly on par with gorilla attacks.
