This is what I would do. No part of the MD5 is any more or less random
or likely to produce collisions than any other bits (AIUI), and any
algorithm that we could come up with are subject to your integer limit
restriction. So it comes down to: is MD5 fast enough for you.

What's the rationale for the requirement to hash to an integer rather
than leave it as is / base 62 / whatever else?
