UUID Generator

UUID Version

Randomly generated. Most commonly used version with very low collision probability.

Quantity

Maximum 500 UUIDs per generation

Version 1: Time-based with MAC address. Guarantees uniqueness but may reveal information about the generating machine.

Version 3: Name-based using MD5 hash. Deterministic but MD5 is considered cryptographically weak.

Version 4: Random/pseudo-random. Most widely used, excellent for general purposes.

Version 5: Name-based using SHA-1 hash. Deterministic and more secure than Version 3.
