示例1: GenerateRandom
void InvertibleESIGNFunction::GenerateRandom(RandomNumberGenerator &rng, const NameValuePairs ¶m)
{
int modulusSize = 1023*2;
param.GetIntValue("ModulusSize", modulusSize) || param.GetIntValue("KeySize", modulusSize);
if (modulusSize < 24)
throw InvalidArgument("InvertibleESIGNFunction: specified modulus size is too small");
if (modulusSize % 3 != 0)
throw InvalidArgument("InvertibleESIGNFunction: modulus size must be divisible by 3");
m_e = param.GetValueWithDefault("PublicExponent", Integer(32));
if (m_e < 8)
throw InvalidArgument("InvertibleESIGNFunction: public exponents less than 8 may not be secure");
// VC70 workaround: putting these after primeParam causes overlapped stack allocation
ConstByteArrayParameter seedParam;
SecByteBlock seed;
const Integer minP = Integer(204) << (modulusSize/3-8);
const Integer maxP = Integer::Power2(modulusSize/3)-1;
AlgorithmParameters primeParam = MakeParameters("Min", minP)("Max", maxP)("RandomNumberType", Integer::PRIME);
if (param.GetValue("Seed", seedParam))
