can we generate a X509 certificate

[Aswin2203]

My Query is about is there any library in python that can generate a X509 certificate using the Post Quantum Cryptography [Open Quantum Safe] Algorithms Key pair [like dilithium] Or is there any other way to generate a X509 certificate using PQC key pairs. It would be so much helpful if you can provide me a solution.

As if I generate a certificate with dilithium key pair using cryptography library, I get this error
ValueError: Unknown key type: 1.3.6.1.4.1.2.267.12.6.5

You can take a look at this open source Python library for the new algorithms. It is written by Markku who is a contributer to this project: https://github.com/mjosaarinen/py-acvp-pqc

So I believe using the above library in conjunction with the X509 Certificate abilities already available in python should allow you to create X509 PQ certificates.
