About UUIDs

UUID (Universally Unique Identifier) is a 128-bit identifier used to uniquely identify information in computer systems.
UUID Versions:
  • UUID v1: Time-based UUID that includes MAC address and timestamp. Useful for sorting by creation time but may reveal MAC address.
  • UUID v4: Random UUID (default). Uses random numbers and is the most commonly used version. The probability of generating duplicate UUIDs is extremely low.
  • UUID v5: Name-based UUID using SHA-1 hashing. Same input (namespace + name) always produces the same UUID. Useful for generating consistent UUIDs from names.

Format: 8-4-4-4-12 hexadecimal digits (e.g., 550e8400-e29b-41d4-a716-446655440000)
