How do I properly change a group's generator in Polar SSL?
Do I just need to copy the new generator into the group, like:
ecp_group group;
ecp_group_init(&group);
ecp_use_known_dp(&group, POLARSSL_ECP_DP_SECP256R1);
ecp_copy(&group.G, &myNewGenerator);
If I just copy the new generator into my group, I get invalid results when performing a multiplication inside the group.
Do I also need to update other variables in the group, like the order (N), when I change the generator?
