示例1: ComputeMessageRepresentative
void DL_SignatureMessageEncodingMethod_DSA::ComputeMessageRepresentative(RandomNumberGenerator &rng,
const byte *recoverableMessage, size_t recoverableMessageLength,
HashTransformation &hash, HashIdentifier hashIdentifier, bool messageEmpty,
byte *representative, size_t representativeBitLength) const
{
assert(recoverableMessageLength == 0);
assert(hashIdentifier.second == 0);
const size_t representativeByteLength = BitsToBytes(representativeBitLength);
const size_t digestSize = hash.DigestSize();
const size_t paddingLength = SaturatingSubtract(representativeByteLength, digestSize);
memset(representative, 0, paddingLength);
hash.TruncatedFinal(representative+paddingLength, STDMIN(representativeByteLength, digestSize));
if (digestSize*8 > representativeBitLength)
{
Integer h(representative, representativeByteLength);
h >>= representativeByteLength*8 - representativeBitLength;
h.Encode(representative, representativeByteLength);
