    • engineGeneratePrivate

      protected PrivateKey engineGeneratePrivate​(KeySpec keySpec) throws InvalidKeySpecException
      This method generates a DSAPrivateKey object from the provided key specification.
      Specified by:
      engineGeneratePrivate in class KeyFactorySpi
      Parameters:
      keySpec - - the specification (key material) for the DSAPrivateKey.
      Returns:
      a DSAPrivateKey object
      Throws:
      InvalidKeySpecException - if "keySpec" is neither DSAPrivateKeySpec nor PKCS8EncodedKeySpec

    • engineGeneratePublic

      protected PublicKey engineGeneratePublic​(KeySpec keySpec) throws InvalidKeySpecException
      This method generates a DSAPublicKey object from the provided key specification.
      Specified by:
      engineGeneratePublic in class KeyFactorySpi
      Parameters:
      keySpec - - the specification (key material) for the DSAPublicKey.
      Returns:
      a DSAPublicKey object
      Throws:
      InvalidKeySpecException - if "keySpec" is neither DSAPublicKeySpec nor X509EncodedKeySpec

    • engineGetKeySpec

      protected <T extends KeySpec> T engineGetKeySpec​(Key key, Class<T> keySpec) throws InvalidKeySpecException
