    - #### extractParameters

          public static ASN1Encodable extractParameters​(java.security.AlgorithmParameters params)
                                                 throws java.io.IOException

      Extract an ASN.1 encodable from an AlgorithmParameters object.
      Parameters:
        `params` - the object to get the encoding used to create the return value.
      Returns:
        an ASN.1 object representing the primitives making up the params parameter.
      Throws:
        `java.io.IOException` - if an encoding cannot be extracted.

    - #### loadParameters

          public static void loadParameters​(java.security.AlgorithmParameters params,
                                            ASN1Encodable sParams)
                                     throws java.io.IOException

      Load an AlgorithmParameters object with the passed in ASN.1 encodable - if possible.
      Parameters:
        `params` - the AlgorithmParameters object to be initialised.
        `sParams` - the ASN.1 encodable to initialise params with.
      Throws:
        `java.io.IOException` - if the parameters cannot be initialised.
