      • 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.
