 One of the most popular ciphers used over 2000 years ago. Following along the "Cracking Codes With Python" book by Al Sweigart, this is an attempt to create an improved and flexible implementation of the cipher that works from the command line. It supports the expected operations of encryption, decryption as well as key derivation and brute forcing.

 A cipher that works by laying the letters of a message in a grid of varying size and encrypting the message from it.

It supports the expected operations of encryption, decryption as well as key derivation and brute forcing.

+#### [Simple Substitution Cipher](https://github.com/herokunt/python-scripts/blob/main/ciphers/simple_sub_cipher.py)
 A substitution cipher uses a re-arranged alphabet (in this case English alphabet) as the key to encrypt a message. This results in too many possible combinations to brute force through each of them in a reasonable amount of time, but can be hacked through cross-referencing each letter from the message. Because of this, it's also most effective the longer the encrypted message. Following along the "Cracking Codes With Python" book by Al Sweigart, this is an implementation that can be used from the command line.
