# Write-up SALAD - RC3 Fall CTF 2016
Challenge text: “The fault, dear Brutus, is not in our stars, but in ourselves.” (I.ii.141) Julius Caesar in William Shakespeare’s Julius CaesarCipher Text: 7sj-ighm-742q3w4t
This challenge provides a Cipher Text, where every character was rotated by 20 positions using a custom alphabet. The custom alphabet: ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789.The challenge was solved using caesar.py, created by rickvg, which can be found in this repository.
Usage:> python caesar.py [integer|all] [input file]
In this case, I removed the dashes (-) from the cipher text as they were not part of the alphabet and used the command:> python caesar.py all cipher
