How we make sure
We check this tool with the automated test suites linked below. Example checks are shown in their original language.
- Verification method
- Compare the DNS namespace/name example with the fixed UUIDv5 vector.
- Comparison reference
- RFC 9562 DNS namespace, www.example.com; fixed vector reproduced by Python stdlib uuid.
- Verification scope
- Only the listed modes and finite examples are covered; this is not an all-input proof.

-

- uuid-v5: DNS namespace vector matches RFC9562
These checks cover the listed examples and boundaries, not every possible input. Round trips and checks using the same library are not independent verification.
