Before moving on, we need to know the facts that make this attack possible: XOR operations cancel out equivalent values (i. In repeating-key XOR, you'll sequentially apply each byte of the key; the first byte of plaintext will be XOR'd against I, the next C, the next E, then I again for the 4th byte, and so on. The method we’ll be using to break the encryption uses statistics (letter frequencies and use of common words, bigrams, and trigrams), so the cipher-text needs to be a decent size otherwise it won’t work.
