UUID Generator

Generate universally unique identifiers (UUIDs) in various versions and formats

UUID Configuration

💡 Tips

  • UUID v4 (random) is the most commonly used and doesn't require additional parameters
  • UUID v1 includes timestamp and MAC address information
  • UUID v3 and v5 are deterministic - same input always produces the same UUID
  • UUID v3 uses MD5 hashing, v5 uses SHA-1 (v5 is recommended over v3)
  • Use standard namespaces like DNS (6ba7b810-9dad-11d1-80b4-00c04fd430c8) for consistent results
  • Generated UUIDs are cryptographically secure and globally unique
