    XOR encryption

    I just finished reading Applied Cryptography and in the very beginning Bruce talks about XOR and how it is an embarrassment of an algorithm. I was wondering if an implementation of XOR with a sliding window, a 32 byte key, and 16 rounds is also a simple task to decrypt for a cryptanalysist.

    Thanks,
    MadCow

    Yes, it's easy to decrypt. It's like a Vigenčre encryptoin.

    Alright, I had assumed as much. I guess I'll spend my time implementing one of the more complex block cipher algorithms, probably AES.
