C++ XOR key is too long?

Question

I have a XOR key (dfficvvifvdfher89429338jwesjcnasidneufhrfdfha23p3rwe23323ncdnhj) but it seems to be way too long, even for long long format.

How can I use this key and get rid of "error C2177: constant too big"?

Put each value into a distinct char in a char array, i.e.:

const char xor_key[] = "dffic...";

You then XOR however-many characters against the key at a time, then use the key again at the next character after that.

That's what the cracker said when he decrypted the message. – Hans Passant Mar 07 '11 at 02:08
