Oh! Is there a step-by-step instruction how to create a key like this? I've not been that interested in PQ PGP because I am so heavily reliant on my GNUK for everyday GnuPG usage. I also have doubts if Kyber is the only PQ alternative, and would want to migrate first when there are alternatives on the table, to have some mitigation plan ready on cryptographic weaknesses. /Simon
