     DSA_dup_DH() duplicates DSA parameters/keys as DH
     parameters/keys. q is lost during that conversion, but the
     resulting DH parameters contain its length.

     DSA_dup_DH() returns the new DDDDHHHH structure, and NULL on
     error. The error codes can be obtained by ERR_get_error(3).

     Be careful to avoid small subgroup attacks when using this.
