Encryption Techniques Python

A simple python script that offers multiple simple implementations for encryption techniques. Done as a project for ASU 2020, Computer and Network Security course.

Supported Encryption Techniques:

• AES
• DES
• Playfair Cipher
• Hill Cipher
• Vernam Cipher
• Vigenere Cipher
• Ceasar Cipher

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

Install the requirements using the following:

pip install -r requirements.txt

or if you are using python venv:

python -m venv venv
venv/Scripts/activate
pip install -r requirements.txt

Running the code

you can get the list of paramters using the following:

python -m encryption --help

or

venv\Scripts\python.exe -m encryption --help

or

venv/Scripts/activate
python -m encryption --help

Output:

usage: __main__.py [-h] -i INPUT [-o OUTPUT] [--caesarCipherEncrypt]
                   [--vigenereCipherEncrypt] [--vernamCipherEncrypt]
                   [--hillCipherEncrypt] [--playfairCipherEncrypt]
                   [--DESEncrypt] [--DESDecrypt] [--AESEncrypt] [--AESDecrypt]

  --caesarCipherEncrypt
                        selects 'caesarCipherEncrypt' as the encryption
                        technique to use. (parameters: key size (shift),
                        default: 3)
  --vigenereCipherEncrypt
                        selects 'vigenereCipherEncrypt' as the encryption
                        technique to use. (parameters: mode(0: repeating, 1:
                        auto), key)
  --vernamCipherEncrypt
                        selects 'vernamCipherEncrypt' as the encryption
                        technique to use. (parameters: key)
  --hillCipherEncrypt   selects 'hillCipherEncrypt' as the encryption
                        technique to use. (parameters: key matrix (elements
                        seperated by ',', e.g. 5,17,8,3))
  --playfairCipherEncrypt
                        selects 'playfairCipherEncrypt' as the encryption
                        technique to use. (parameters: key)
  --DESEncrypt          selects 'DESEncrypt' as the encryption technique to
                        use. (parameters: key(16 Hex Chars), Number of rounds)
