I don't understand what's going on here. What sort of key is this? Are
they just verifying that it has some format? Are they running it
against a list of known good keys? or were they serious enough to use
public/private key signing?

Also how much does this matter? When you "send commands directly",
like in ::Tecan, do you still require a key?
