Supported GUID versions by this generator
This generator intentionally supports only secure, modern GUID versions - v4 and v7. Older or deprecated versions such as v1, v2, v3, v5, v6 and v8 are not supported because they rely on outdated hashing algorithms, expose hardware or user identifiers, lack modern security guarantees or are intended for custom implementations without standardized structure.
