Jun. 7th, 2026 01:51 pmI'm not really a big worrier about post-quantum encryption. I don't think we'll see a practical breach of RSA2048 in my life time.
But _customers_ might be, so we need to know how to do this properly.
To my surprise I found my previous Debian 13 configuration was now being flagged as offering post-quantum ciphers, despite me not making any changes; the previous work I'd done with getting RSA and ECDSA working together was enough!
So I figured I should document how I achieved this feat :-)
