C++ Simple Encryption Algorithm XOR

Code:

string XOR(string data, char key[])
{
	string xorstring = data; //initialize new variable for our xordata
	for (int i = 0; i < xorstring.size(); i++) { //for loop for scrambling bits in the string
		xorstring[i] = data[i] ^ key[i % (sizeof(key) / sizeof(char))]; //scrambling the string/descrambling it
	}
	return xorstring;
}

Thanks for the contribution, what would you use this encryption for typically?

Wouldn't use this for files, big data, messages, or any sensitive information. XOR Cipher is pretty easy to crack by analyzing patterns.
But this could be used (needs implementation) to for example encrypt memory of a program at runtime, or secure strings inside a program. This would have good
use for encrypting connections/packets too.

You could also release a "how to crack XOR encryption" now!
