一个简单有效的加密算法

附上代码与运行结果

源代码：

#include <iostream>
#include <string>

using namespace std;

void simple_encrypt(const string & org, string & encrypted, int key)
{
	for (int temp = 0; temp < org.size(); temp++)
	{
		encrypted += org[temp] ^ (int(key) + temp) % 255;
	}
}

void simple_unencrypt(const string &encrypted, string &unencrypted, int key)
{
	simple_encrypt(encrypted, unencrypted, key);
}

int main(int argc, char *argv[])
{
	string original = "super flying monkeys are aweseome, aren't they?";
	cout << "Original data = " << original << endl;
	string encrypted = "";
	string unencrypted = "";
	char key = 'x';
	
	simple_encrypt(original, encrypted, key);
	cout << "Encrypted data = " << encrypted << endl;
	
	simple_unencrypt(encrypted, unencrypted, key);
	cout << "Unencrypted data = " << unencrypted << endl;
	
	return 0;
};

运行结果示例：
