What is a UUID?
Unique Identifier
A 128-bit number used to identify information in computer systems. The probability of a duplicate is virtually zero.
Standardized Format
Represented as a 32-character hexadecimal string, separated by hyphens: 8-4-4-4-12.
Decentralized
Can be generated independently without a central authority, making them ideal for distributed systems.
Common Versions
Version 4 (Random)
Generated from purely random or pseudo-random numbers. This is the most common version.
Version 1 (Time-based)
Generated from a timestamp and the MAC address of the generating computer.
Version 5 (Name-based)
Generated from a namespace and a name, hashed with SHA-1. Guaranteed to be unique for the same inputs.
Common Use Cases
Database Keys
Use as primary keys in distributed databases to avoid collisions between records.
