In my implementation, it's needed in two places. * For ecdsa signatures, the random nonce k is inverted mod q, the ecc group order. * When converting coordinates back from jacobian representation to affine representation. Then the z coordinate is inverted mod p. > My suggestion was just for a reasonably efficient fall-back. Fair enough. /nisse -- Niels Möller. PGP-encrypted email is preferred. Keyid C0B98E26.
