UUID Information
Learn about different UUID versions and their use cases
UUID v1 (Timestamp)
Based on timestamp and MAC address. Guarantees uniqueness but may reveal information about when and where it was generated.
UUID v3 (MD5)
Generated using MD5 hash of namespace and name. Deterministic - same inputs always produce the same UUID.
UUID v4 (Random)
Randomly generated. Most commonly used version. Provides good uniqueness with minimal information leakage.
UUID v5 (SHA-1)
Generated using SHA-1 hash of namespace and name. More secure than v3 and also deterministic.
