  • Montgomery: y^2 = x^3 + A x^2 + x mod P (Curve25519, - * Curve448)
- * In both cases, the generator (\p G) for a prime-order subgroup is fixed. - * - * For Short Weierstrass, this subgroup is the whole curve, and its - * cardinality is denoted by \p N. Our code requires that \p N is an - * odd prime as mbedtls_ecp_mul() requires an odd number, and - * mbedtls_ecdsa_sign() requires that it is prime for blinding purposes. - * - * The default implementation only initializes \p A without setting it to the - * authentic value for curves with A = -3(SECP256R1, etc), in which - * case you need to load \p A by yourself when using domain parameters directly, - * for example: - * \code - * mbedtls_mpi_init(&A); - * mbedtls_ecp_group_init(&grp); - * CHECK_RETURN(mbedtls_ecp_group_load(&grp, grp_id)); - * if (mbedtls_ecp_group_a_is_minus_3(&grp)) { - * CHECK_RETURN(mbedtls_mpi_sub_int(&A, &grp.P, 3)); - * } else { - * CHECK_RETURN(mbedtls_mpi_copy(&A, &grp.A)); - * } - * - * do_something_with_a(&A); - * - * cleanup: - * mbedtls_mpi_free(&A); - * mbedtls_ecp_group_free(&grp); - * \endcode - * - * For Montgomery curves, we do not store \p A, but (A + 2) / 4, - * which is the quantity used in the formulas. Additionally, \p nbits is - * not the size of \p N but the required size for private keys. - * - * If \p modp is NULL, reduction modulo \p P is done using a generic algorithm. - * Otherwise, \p modp must point to a function that takes an \p mbedtls_mpi in the - * range of 0..2^(2*pbits)-1, and transforms it in-place to an integer - * which is congruent mod \p P to the given MPI, and is close enough to \p pbits - * in size, so that it may be efficiently brought in the 0..P-1 range by a few - * additions or subtractions.
