I was going to post the whitespace programming language but this wins

Your workaround is precisely why I said “more practical”. Any updates to your tooling might break it because it’s not an expected usecase

You don’t want FIDO2 security tokens for that, use an OpenPGP applet (works with some Yubikeys and with many programmable smartcards). Much more practical for authenticating a server.

BTW we have a lot of cryptography experts in www.reddit.com/r/crypto (yes I know, I’m trying to get the community moved, I’ve been moderating it for a decade and it’s a slow process)
