Are tcIds stable? about wycheproof HOT 8 CLOSED

Hi Brian,

The tcId aren't stable for now.

@bleichen Daniel, can we keep the tcId stable?

from wycheproof.

No. tcIds are not stable. They change every time the test vectors are generated and are only useful as identifier of a test vector if the version
of the test vectors is also known. There are no plans to make them stable. I.e. the test vector generation often sorts the test vectors by key so that vectors with the same key are in the same test group. So adding test vectors to one group, changes the tcIds in the next group.

For citing a test vector, it is probably reasonable to just copy the test vector.
For excluding test vectors with legacy behavior, I'm adding flags to the test vectors.
For documentation there are comments in the test vectors that can point to CVE or other
references.

OK, thanks for the explanation.

I understand that the test vectors aren't copyrightable and so the license doesn't apply to them. However, it would be great if that could be made explicit in the LICENSE file.

The main question is answered, so I'm going to close this ticket.

Hey Brian,

Just curious, why you think the test vectors are not copyrightable? Can you use them even if they are under the Apache 2 license? We want you to use them, but we're not sure if we can convince the lawyers to exclude the test vectors from the copyright notice.

Friendly ping Brian.

I am able to use the test vectors without any changes.

from wycheproof.

Cool.
