Enigma

Enigma is a web-based cryptography tool that allows you to encrypt, decrypt, and attack texts and images using a variety of classic and modern ciphers, including block ciphers

Deployed Project: https://enigma-crypto.herokuapp.com

Note: The project is currently offline due to because heroku free tier no longer exists.

Enigma supports the following cryptsystems:

Classic ciphers

The following ciphers are implemented for text encryption only:

• Shift cipher
• Affine cipher
• Substitution cipher
• Hill cipher
• Permutation cipher
• Vigenere cipher

Block ciphers

The following cipher are implemented for image encyption:

• Triples DES
• AES
• Simplified DES(text only)

Public ciphers

The following ciphers are implemented for text encryption only:

• RSA
• Rabin
• ElGamal (Discrete Logarithm)
• ElGamal (Eliptic Curve)

This app is deployed on website, however if you want to deploy it in your local machine you need to:

• Install Node >= 16.* and NPM Download

To begin, install Angular-CLI with npm using the following command:

npm install -g @angular/cli

Next, please follow the next steps to install the requirements:

# We assume you are in the root folder of the repo
cd backend

# It's recommended to do the following command inside a virtual environment
pip install -r requirements.txt

Set the FLASK_APP environment variable:

(Unix/Mac) export FLASK_APP=colossus
(Windows) set FLASK_APP=colossus
(Powershell) $env:FLASK_APP="colossus"

4. Run the application backend locally:

flask run

Now for the frontend:

# We assume you are in the root folder of the repo
cd frontend

npm install 
ng serve 

Now you can go to http://localhost:4200 and test the app.

You can easily run the project using the provided Dockerfile.

Run:

# /path/to/enigma
docker build -t enigma .
docker run -it -v /path/to/enigma:/home/user/enigma -p 4200:4200 -p 5000:5000 enigma /bin/bash
user@dockerid:~$ cd enigma/backend python3 -m flask run -h 0.0.0.0
user@dockerid:~$ cd ../frontend && npm install && ng serve --host 0.0.0.0

Now you can go to http://localhost:4200 and test the app.
