Can I use Yubikey to encrypt a file without PGP?
I have a Yubikey 5 Series and would like to use it to encrypt a file, so that a physical presence of my Yubikey would be required to decrypt it.
I know you can save a PGP key onto Yubikey and use it for this purpose. However, I am planning to use the PGP encryption key for something different and would like to narrow the attack surface by not using it to encrypt my file. If there was a way to have two PGP encryption keys on a Yubikey, I would gladly do that, but AFAIK there can only be one encryption PGP key on a Yubikey.
Is there a way to use some other facility that Yubikey 5 Series offers - e.g. PIV, FIDO2 - to encrypt a file?
