You can always use a truncated hash - for instance, take the first 6-8
hex digits of the MD5 or SHA1 hash. For human readability, that's
likely to be all you need (for instance, git references commits by
their SHA1 hashes, but you can work with just the first six digits
quite happily). Otherwise, can you provide more details on why you
need a hash, and why it wants to be shorter than the original?
