C++ (Cpp) DecryptInitialTransfomation Examples

Example #1

void Decrypt(uint8_t *block, uint8_t *roundKeys)
{
	int8_t i;
	int8_t* prk = roundKeys + 132;

	DecryptFinalTransfomation(block, roundKeys);

	for(i = 0; i < NUMBER_OF_ROUNDS; ++i) {
		DecryptRoundFunction(block, prk);
		prk -= 4; 
	}

	DecryptInitialTransfomation(block, roundKeys);
}
