MD5 is a poor choice, though it's probably OK for this sort of very short plain-text prediction. SHA-1 is looking fairly sha-ky too these days, but again is probably fine for this purpose. If you're picking a hash function for actual cryptographic purposes, SHA-256 would be a better choice.

This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
