Parameters
- secretKey
- The secret key.
Secret keys are represented in various of ways and the plugin will preprocess them correctly to take all representations.
For example then all of the following keys are equal:
N7P7TWR3Q5WUA2XG
N7P7 TWR3 Q5WU A2XG
n7P7 tWR3 q5WU a2XG - algorithm
- The algorithm to use. Standard implementation uses HMAC_SHA1.
- digits
- Digits to use. Standard implementation uses six.
- seconds
- Seconds for the time window. Standard implementation is 30 seconds.
- secondsRemaining (ByRef parameter)
- ByRef parameter which returns how many seconds are remaining of the 30 second window.
