Man these spot the difference games are getting hard

Table of Contents

Cipher, cipher, cipher.

Problem

 -----------------------------------------------------------------------
 Welcome to DiffSpot, a new Spot the Differnce Game sponsored by DawgSec
           You'll be presented with a variety of encoded data,
               all of which will be of the form DogeCTF{}
 Possible ciphers include:
 - rot13
 - rot16
 - base64
 - base32
 - base16
 - atbash
 - affine with b=6, a=9
 - railfence with key=3
          Your job is to decode the flag and send it back to us
                      Seems easy enough right?
 -----------------------------------------------------------------------

Solution

Just implement those ciphers!
