      Specified by:
      engineGeneratePrivate in class KeyFactorySpi
      Parameters:
      keySpec - the specification (key material) of the private key
      Returns:
      the private key
      Throws:
      InvalidKeySpecException - if the given key specification is inappropriate for this key factory to produce a private key.
    • engineGetKeySpec

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