Usage

Register service

serviceCollection.AddOtpProvider();

In your service / controller:

// inject the service
IOTPProvider otpProvider; 

// generate a secret
var secret = "<some random string>";

// define the length of the password to generate
var passwordLength = 6;

// indicates whether the secret's spaces matter or not.
var ignoreSpaces = false; // false: Spaces matter. true: Spaces don't matter

var otp = otpProvider.GetPassword(secret, passwordLength, ignoreSpaces);

// the adjacent intervals to check for the OTP. The greater this value is, the higher risk of being hijacked.
var checkAdjacentIntervals = 2;

var isOtpValid = otpProvider.ValidateOTP(otp, secret, ignoreSpaces, checkAdjacentIntervals;
