      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.

          public AsymmetricCipherKeyPair generateKeyPair()

      Given the domain parameters this routine generates an EC key pair in accordance with X9.62 section 5.2.1 pages 26, 27.
      Specified by:
        `generateKeyPair` in interface `AsymmetricCipherKeyPairGenerator`
      Returns:
        an AsymmetricCipherKeyPair containing the generated keys.
