In this update, I did the following thing mostly :

1. Firstly, I removed the pycache/ folder from the repo, which was consuming waste storage + also ignored all kind of the python cache directories in all major roots.
2. Made the code clean and error free.
3. Added the function of quiting the script immediately when the user presses the CTRL+C.
4. Added the commented docs, making things easy for the readers of the code. So, the overall change is made to the Cryptography/ directory scripts (tools). Hope so you review my contribution to this repository, and hope so you merge it soon.

hey @rdofficial, Thanks for your contribution, I think your changes contain a bit of useless information like the description of the contributors and modification times, If you remove that information I'll merge the pull.
