Creates a parameter specification for EC parameter
generation using a standard (or predefined) name
stdName in order to generate the corresponding
(precomputed) elliptic curve domain parameters. For the
list of supported names, please consult the documentation
of provider whose implementation will be used.

Params:
  • stdName – the standard name of the to-be-generated EC
domain parameters.
Throws:
/**

     * @param stdName the standard name of the to-be-generated EC
