public class KeyPairGeneratorSpi extends KeyPairGeneratorSpi
KeyPairGenerator class for composite signatures. Selected algorithm is set by the "subclasses" at the end of this file.

  • Method Details

    • initialize

      public void initialize(int keySize, SecureRandom random)
      Native public method. There is no notion of a keysize for composite signatures. Therefore, this method is unsupported. For setting a custom SecureRandom the other initialize method must be used.
      Specified by:
      initialize in class KeyPairGeneratorSpi
      Parameters:
      keySize -
      random -

    • initialize

      public void initialize(AlgorithmParameterSpec paramSpec, SecureRandom secureRandom) throws InvalidAlgorithmParameterException
      Setting custom AlgorithmParameterSpec is not supported since the composite signature algorithm definition allow only for one specific parameter spec which is initialized by the initializeParameters method. This method only serves to set a custom SecureRandom.
      Overrides:
      initialize in class KeyPairGeneratorSpi
      Parameters:
      paramSpec - Unsupported, needs to be null.
      secureRandom - A SecureRandom used by component key generators.
      Throws:
      InvalidAlgorithmParameterException
