[WIP] A cryptographic string encryption program implementing the Caesar Cipher using Python.

Cyber Cipher

A cryptographic Caesar Cipher Encryption Program

Cyber Cipher is designed to take in a string of characters a user enters in in order to return an encrypted version of the string.

Here's the live app site: https://cybercipher.herokuapp.com

• In your Terminal, run python main.py

Technologies Utilized

1. Python 3.6+
2. Flask
3. Jinja2 as an HTML templating engine
4. HTML5
5. CSS3
6. Semantic UI framework
7. Heroku for deployment & Procfile
8. Pipenv for build pack

Why I Built The Cyber Cipher

I was looking for interesting projects to build where I could set up a server and focus more on backend than frontend code. I wanted to utilize modern technologies while excluding unnecessary build tools for the sake of simplicity and thus, lack of necessity.

What I'm Learning While Building This Program

• Software Architecture matters more than any other aspect of building an app or program that implements client and server-side development.
• Do not assume the data structure of what certain methods from imported packages and/or modules will return. Read the documentation for interpreting/ingesting such data.

Impending Feature Additions

1. Docker container implementation
2. Additional cryptographic cypher implementations with sidebar menu of options
3. Information / Definition glossary page as tab in sidebar menu of cipher options
4. Hot reloading for server in order to reduce amount of server kills from errors

Current Limitations to the Program

• Users cannot enter in special characters (non English alphabetic characters into encryption input field without causing an error in the program
• Users must enter in a string with no whitespace as a result of KeyError
• No testing for this program has occurred on machines with other operating systems
• Lack of error handling in order to reroute program and prevent server crashes
• Lack of rerouting and input value clearing subsequent to running the encryption program successfully
