25 Javascript Generate Short Uuid

One way to make them shorter is to use fewer bytes. But that's annoying (there's lots of good tools to make 256-bit UUIDs, not so many to make, say, 128-bit ones), and defeats a lot of the benefits. Another way, however, is to use a different textual representation - particularly if you're just using this as an identifier.

A way to do so is to create a SHA-256 hash out of the ID, and then use its first few characters. The UUIDv4 implementation uses random numbers as the source. The Java implementation is SecureRandom, which uses an unpredictable value as the seed to generate random numbers to reduce the chance of collisions. Let's generate version 4 UUID: UUID uuid = UUID.randomUUID ();

But the shorter it is, the higher the rate of collision is and therefore, the ID won't be unique.
