The subdomain https://www.humanmo.de/ uses a classic CA with ECDSA algorithm for its server certificate chain (thanks to Let's Encrypt).
The same content is also available through the subdomain https://pq.humanmo.de/ which uses a pure post quantum CA, with ML-DSA algorithm for every certificate in the chain.
To try it out, download my PQ root CA certificate,
set it as trusted root CA certificate in your web client (you should only do this for experimental usage)
and access https://pq.humanmo.de/
Until browser implementations catch up, you probably need a command line client like curl to make a successful connection.
Details of the PQ root certificate:
