Properties
the length of the generated code. The RFC 4226 requires a code digits value between 6 and 8 to assure a good security trade-off. However, this library does not set any requirement for this property. But notice that through the design of the algorithm the maximum code value is 2,147,483,647. Which means that a larger code digits value than 10 just adds more trailing zeros to the code (and in case of 10 digits the first number is always 0, 1 or 2).
the "keyed-hash message authentication code" algorithm to use to generate the hash, from which the code is extracted (see HmacAlgorithm for available algorithms).
represents together with the timeStepUnit parameter the time range in which the challenge is valid (e.g. 30 seconds).
