Cracking Codes with Python

What is it?

A work through of the book Cracking Codes with Python

I read the book, this isn't the example code from it

Yeah, writing a bunch of singular app files wasn't how I wanted to do it. So I went a slightly more OOP route.

How can I help?

🤷 I mean, it is a walkthrough of a book. I don't think there is much to do after the book is done. Although I may go through and create a different release with a bit more of a proper setup for fun.

How do I use it?

usage: main.py [-h] [-rs] [-cc] [-bf] [-tc] [-k KEY] [-m MESSAGE] [-d] [-e] [-if INPUTFILE] [-of OUTFILE]

Different cipher stuff from the book Cracking Codes with Python

optional arguments:
-h, --help show this help message and exit

modes:
-rs, --reversestring Performs a basic string reversal. Use with -if and -of to reverse an entire text file.
-cc, --caesarcipher Performs a basic Caesar cipher. Returns all lower case letters. Requires: -k/--key and -m/--message . Use with -if and -of to do an entire file.
-bf, --bruteforce Use to bruteforce a cipher_text created with a Caesar cipher if the key is not known.
-tc, --transpositioncipher Use for a Transposition cipher. Requires -m -k , use with -if and -of to do an entire file

inputs:
-m MESSAGE, --message MESSAGE
Message to decrypt/encrypt.
-if INPUTFILE, --inputfile INPUTFILE Full path to file to decrypt/encrypt
-of OUTFILE, --outfile OUTFILE Full path to file for result of decrypting/encrypting -if.

required:
-k KEY, --key KEY The key for a Caesar or Transposition Cipher. Required to be of type int
-d, --decrypt Set mode to decrypt.
-e, --encrypt Set mode to encrypt
