C++ (Cpp) SymmetricKey::setKeyBits Examples

Example #1

File: OSSLDES.cpp Project: bellgrim/SoftHSMv2

bool OSSLDES::generateKey(SymmetricKey& key, RNG* rng /* = NULL */)
{
	if (rng == NULL)
	{
		return false;
	}

	if (key.getBitLen() == 0)
	{
		return false;
	}

	ByteString keyBits;

	// don't count parity bit
	if (!rng->generateRandom(keyBits, key.getBitLen()/7))
	{
		return false;
	}

	// fix the odd parity
	size_t i;
	for (i = 0; i < keyBits.size(); i++)
	{
		keyBits[i] = odd_parity[keyBits[i]];
	}
