Composite-ML-DSA: Known good test vectors?

[Stephan Müller]

Hi,

although leancrypto provides already a composite ML-DSA, it was not compliant
to the current IETF draft [1].

After now bringing it into compliance, including the generation of X.509
certificates, I am wondering whether there are known good test vectors for
this algorithm implementation. Specifically I would like to test the
correctness of my input message processing as defined in the algorithm step 2.

Thanks a lot.

Hi Stephan,

Do you have any leads now on where to get the vectors ?

Thanks,

You can find them at the IETF-Hackathon which provides vectors from a large
number of implementations:

https://github.com/IETF-Hackathon/pqc-certificates/tree/master/providers

Search for artifacts_certs_r4.zip files, such as

https://github.com/IETF-Hackathon/pqc-certificates/blob/master/providers/
leancrypto/artifacts_certs_r4.zip


Or you also find certificates at the leancrypto code tree which has been
verified against several other implementations (see [1]): https://github.com/
smuellerDD/leancrypto/tree/master/asn1/tests/testcerts


You can generate your own certificates as outlined in: https://leancrypto.org/
leancrypto/x509_support/index.html
