Deterministic Logic

Version 3 UUIDs are created by hashing a namespace and a name using MD5. This ensures that the same input always produces the same unique identifier across different systems.

Namespace Scoping

Scoped IDs allow you to convert existing strings (like usernames, URLs, or file paths) into standard 128-bit UUIDs within a specific context, avoiding global collisions.
