📚 UUID Information

UUID v1 (Time-based)

Generated based on timestamp and MAC address. Provides uniqueness across space and time but may reveal information about when and where it was generated.

UUID v4 (Random)

Generated using random or pseudo-random numbers. Provides excellent uniqueness without revealing any information about the generator. Recommended for most use cases.

Nil UUID

Special UUID where all bits are set to zero. Used as a placeholder or to indicate the absence of a UUID value in applications.

Use Cases

Database primary keys, distributed system identifiers, session tokens, file names, API request IDs, and any scenario requiring unique identifiers.
