UUID v4 vs UUID v1 – Which to Use?
Generated using cryptographic randomness. No timestamp, no machine info. Best for most use cases.
Encodes current timestamp. Sequential UUIDs, better for time-ordered databases.
Use UUIDs as table primary keys for distributed systems without ID coordination.
UUIDs as REST API resource identifiers prevent enumeration attacks.
Generate unique session IDs that cannot be guessed or predicted.
Use UUID as unique filenames to avoid collisions in file storage systems.
