XOR Encryption

[butaktelco]

Hello,
anybody know XOR algorithm, i have discover on the net still don't get any result.

there is code for decrypting.


char *result_decode = new char[100];
for(int i = 1; i < 100; ++i){
result_decode[i]= encode_data[i] ^ (0xE3 << (i & 3));
}


any suggestion how to encryption back of byte.

Just "swap" 'result_decode' and 'encode_data'.
Xor is a reversible operation.
