Network Programming in .NET

U2F is a new standard in hardware dongles that will become more prevalent as stronger 2FA Auth becomes more commonplace, due to PSD2 regulations etc.

I’m just learning, so this demo does nothing much at the moment, other than trigger the registration procedure on the U2F device, and, so far – it runs entirely in client side javascript.

It requires the U2F library from Google.

let registerRequest = {
challenge: ‘RegisterChallenge’,
version: ‘U2F_V2’
}
u2f.register(‘https://localhost’, [registerRequest], [],
(response) => {
debugger;
console.log(response);
}
);

I’ll be develping this over a few days, if I get time to experiment!
