The challenge type.

Possible Values

  0 (ctRandom), 
  1 (ctSignature)

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for the getChallengeType([callback]) method is defined as:

function(err, data){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'data' is the value returned by the method.

The callback for the setChallengeType([callback]) method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This property defines the type of challenge created. Possible values are:

0 (ctRandom - default) A random challenge is created.
1 (ctSignature) A signature challenge is created by signing ChallengeInput.

When setting this property to 0 (ctRandom) and calling CreateChallenge the class will populate Challenge with a randomly generated value.

When setting this property to 1 (ctSignature) and calling CreateChallenge the class creates a Hash-based Message Authentication Code (HMAC) value using the data specified in ChallengeInput and then populate Challenge with the formatted result.
