When I've been talking about hashes, I've been assuming very strong cryptographic hashes, good enough that you can trust equal results to really be equal without having to verify by a comparison.
I am not an expert in this field. All I know is that MD5 and SHA1 can create collisions. Are there stronger algorithms that do not? And, more importantly, has it been *proved* that they do not?
