Understanding UUIDs
UUIDs (Universally Unique Identifiers) are 128-bit identifiers designed to be unique across space and time.
- v1: Time-based, includes MAC address info.
- v4: Randomly generated, most common for secure IDs.
- v5: Generated from a namespace and name using SHA-1, deterministic for same inputs.
