    - #### init

          public void init(KeyGenerationParameters param)

      Description copied from interface: `AsymmetricCipherKeyPairGenerator`
      intialise the key pair generator.
      Specified by:
        `init` in interface `AsymmetricCipherKeyPairGenerator`
      Parameters:
        `param` - the parameters the key pair is to be initialised with.

    - #### generateKeyPair

          public AsymmetricCipherKeyPair generateKeyPair()

      Generate a new XMSSMT private key / public key pair.
      Specified by:
        `generateKeyPair` in interface `AsymmetricCipherKeyPairGenerator`
      Returns:
        an AsymmetricCipherKeyPair containing the generated keys.
