Method Detail

• getBlockSize

  int getBlockSize()

  Return the block size of the DRBG.

  Returns:

  the block size (in bits) produced by each round of the DRBG.

• generate

  int generate​(byte[] output,
               byte[] additionalInput,
               boolean predictionResistant)

  Populate a passed in array with random data.

  Parameters:

  output - output array for generated bits.

  additionalInput - additional input to be added to the DRBG in this step.

  predictionResistant - true if a reseed should be forced, false otherwise.

  Returns:

  number of bits generated, -1 if a reseed required.

• reseed

  void reseed​(byte[] additionalInput)

  Reseed the DRBG.

  Parameters:
