Generate random v4 UUIDs (Universally Unique Identifiers) for use in software development.
In distributed systems, you can't just count 1, 2, 3... because two servers might pick '2' at the same time. UUIDs (Universally Unique Identifiers) solve this by being mathematically guaranteed to be unique.
Need a primary key for a database? A session ID? Using a UUID v4 means you never have to check a central server for collisions.

A UUID is 128 bits long. The probability of a collision is so low that you would have to generate 1 billion UUIDs per second for 85 years to have a 50% chance of one duplicate.
