mplementations are based on this one. EC_GFp_mont_method builds on EC_GFp_simple_method but adds the use of montgomery multiplication (see <a href="../man3/BN_mod_mul_montgomery.html">BN_mod_mul_montgomery(3)</a>). EC_GFp_nist_method offers an implementation optimised for use with NIST recommended curves (NIST curves are available through EC_GROUP_new_by_curve_name as described in <a href="../man3/EC_GROUP_new.html">EC_GROUP_new(3)</a>).</p>
