RegisterCommand Class

Namespace: Yubico.YubiKey.U2f.Commands Assembly: Yubico.YubiKey.dll

Creates a U2F registration on the device.

C#

public sealed class RegisterCommand : U2fBufferCommand, IYubiKeyCommand<RegisterResponse>

Inheritance object U2fBuffer U2fBufferCommand RegisterCommand

Implements

IYubiKeyCommand<RegisterResponse>

Remarks

The partner Response class is RegisterResponse.

This command will generally initially return a ConditionsNotSatisfied and will not return success until the user confirms presence by touching the device. Clients should repeatedly send the command as long as they receive this status.

Example:

IYubiKeyConnection connection = key.Connect(YubiKeyApplication.FidoU2f);
byte[] challenge = new byte[32];
RandomNumberGenerator.Fill(challenge);
byte[] appId = new byte[32];
RandomNumberGenerator.Fill(appId);
RegisterCommand registerCommand = new RegisterCommand(challenge, appId);

RegisterResponse registerResponse;
do
{
    registerResponse = fidoConnection.SendCommand(registerCommand);
} while (registerResponse.Status == ResponseStatus.ConditionsNotSatisfied);
RegistrationData data = registerResponse.GetData();
