* Data validation

SetBytesWithClamping returns nil and an error, and the receiver is unchanged. // // Note that since Scalar values are always reduced modulo the prime order of // the curve, the resulting value will not preserve any of the cofactor-clearing // properties that clamping is meant to provide. It will however work as // expected as long as it is applied to points on the prime order subgroup, like // in Ed25519. In fact, it is lost to history why RFC 8032 adopted the // irrelevant RFC 7748 clamping, but it is now...
