Method Detail

getKeyModulus

public int getKeyModulus()

Returns the key module.

Returns:

the key module.

getKeyRepresentation

public KeyRepresentation getKeyRepresentation()

Returns the key representation.

Returns:

the key representation.

getCodeDigits

public int getCodeDigits()

Returns the number of digits in the generated code.

Returns:

the number of digits in the generated code.

getTimeStepSizeInMillis

public long getTimeStepSizeInMillis()

Returns the time step size, in milliseconds, as specified by RFC 6238. The default value is 30.000.

Returns:

the time step size in milliseconds.

getWindowSize

public int getWindowSize()

Returns an integer value representing the number of windows of size timeStepSizeInMillis that are checked during the validation process, to account for differences between the server and the client clocks. The bigger the window, the more tolerant the library code is about clock skews.

We are using Google's default behaviour of using a window size equal to 3. The limit on the maximum window size, present in older versions of this library, has been removed.

Returns:

the window size.
