@newtfrank You can truncate the hash value (take only a subset of the returned string and use that), but if you take too much of it out, it will negate the useful properties of the hash function. Here are a couple of StackExchange answers talking about when truncation is safe (and when it might not be): [1] [2]. Also take a look at this page for a bit of background on hash functions and the difference between them and encryption. Cheers!
