WebAug 10, 2013 · ArgumentParser ( description='cribdrag, the interactive crib dragging script, allows you to interactively decrypt ciphertext using a cryptanalytic technique known as "crib dragging". This technique involves applying a known or guessed part of the plaintext (a "crib") to every possible position of the ciphertext. I'm not sure why it's broken into separate lines, but my guess is that it has to do with spaces in the cipher text XOR result...encasing the return of the string_xor function inside of another join, seems to do the trick though, but because it doesn't seem to affect the results of the crib drag, I left it out of the provided code:
