TOTP class
TOTP class will generate the OTP (One Time Password) object with the current or given time.
Constructors

Methods
-
now(
) → String - Generate the TOTP value with current time. [...]
-
value(
{DateTime date }) → String - Generate the OTP with a custom time. [...]
-
verify(
{String otp, DateTime time }) → bool - Verifies the TOTP value passed in against the current time. [...]
-
generateOTP(
{int input, OTPAlgorithm algorithm: OTPAlgorithm.SHA1 }) → String -
When class HOTP or TOTP pass the input params to this
function, it will generate the OTP object with params,
the params may be counter or time. [...]
