Could you explain this one to me? I think I am missing something. The way I see it, you have a target file which is unknown to you, and a random key which are XOR'd into the encrypted version. Wouldn't Random plus an unknown content (despite being ordered/logical) still be random? Did you go by the fact that you knew it was source code you were decrypting so you knew to look for obvious text such as #define, or #include, or main If I took a file, and did some alphabet substitutions on it so that it no longer had a language form, and then XOR'd it to random data, would you still be able to decipher/unobscure it? thanks!
