Refreshing my knowledge on cryptography related topics: OpenPGP, RSA, ed25519.

Looking around yubikey firmware updates and curious what they mean "Expansion and enhancement of public key algorithms" in firmware 5.7. I think RSA-4096 and ed25519 are already supported since 5.2.3. 🤔

My current yubikey 5c nano have a broken sensor, so I can't use it for FIDO/TOTP, considering to replace it with 5 nano and 5 NFC (backup)
