Enquiry: Regarding YubiKey 5C NFC

[AbramTTP]

Hi Brush701,

I stumbled upon this good plugin here and since I just got my Yubikey 5C NFC and wondering if I can use it as a 2FA method for my kdbx I decided to give it a test even though it's the newest key in the 5 Series family.

It works so far, although I have a question, because I had to tick "Variable Length Challenge" to make the secret key work, yet your instructions under "Running" section says:

"Ensure that the challenge is set to fixed 64 byte (the Yubikey does some odd formatting games when a variable length is used, so that's unsupported at the moment)"

And the Yubikey Manager's (Not the Personalization Tool, which, as far as I know, is no more. I am a very new hardware key user for only a few weeks transitioning as much as possible from TOTP) Challenge-Response settings only gives me 40 characters (20 bytes) hex value.

Just wondering will it give me issues in the future? I have been able to login to my database a few times so far. Thank you.
