So I've picked up this interessting book "Hacking secret Ciphers with Python" (get it for free
here) and it contained a part where the Ceaser Cipher is beeing bruteforced, most of the code is from the book mentioned above, I've just extended it to check for a valid string instead printing out all possible strings. Its nothing special but I hope some find it somewhat useful
attached to this post is my source with a list of about 5k words which is beeing used by the script, feel free to use it how you like!

Usage: script.py -m "your encrypted ceaser cipher string"
Enjoy
