UUID Generator

Generted UUID Universally Unique Identifier

What is UUID Generator?

A UUID (Universally Unique Identifier) is a 128-bit value, usually written as 32 hexadecimal digits in five groups, like 123e4567-e89b-12d3-a456-426614174000.

It lets different computers create identifiers on their own with almost no chance of two being the same.

What this tool does

Generates a UUID of the version you select: NIL (all zeros), version 1 (time based), version 3 or 5 (name based) or version 4 (random).

How to use it

  1. Choose the UUID version.
  2. Copy the generated UUID.
  3. Generate a new one whenever you need another.

Did you know?

  • Version 4 is the most common because it is simply random.
  • Versions 3 and 5 always give the same UUID for the same name and namespace; version 3 uses MD5 and version 5 uses SHA-1.
  • The chance of two random version 4 UUIDs colliding is so small that it can be ignored in practice.
