A new curve can be constructed by calling EC_GROUP_new, using the implementation provided by B<meth> (see L<EC_GFp_simple_method(3)>).

EC_GROUP_set_curve_GFp sets the curve parameters B<p>, B<a> and B<b> for a curve over Fp stored in B<group>. EC_group_get_curve_GFp obtains the previously set curve parameters. |
