About UUIDs
A Universally Unique Identifier (UUID) is a 128-bit label used for information in computer systems. UUIDs are standardized by the Open Software Foundation (OSF).
- UUID v1: Time-based (MAC address + timestamp)
- UUID v4: Random (uses cryptographically strong random values)
- UUID v5: Namespace-based (using SHA-1 hash)
Common Use Cases
Database Records: Primary keys that don't expose sequential information.
Distributed Systems: Generate IDs without coordination between nodes.
API Development: Create unique request IDs for tracking and debugging.
Session Management: Generate unique session identifiers.
Security: Creating API keys, reset tokens, and other secure identifiers.
