Hash function that produces short hashes?
...t, like MD5 (128 bits) or SHA1 (160). Then you can shorten that further by XORing sections of the digest with other sections. This will increase the chance of collisions, but not as bad as simply truncating the digest.
Also, you could include the length of the original data as part of the result to...
