ChatOTP

ChatOTP is a chat protocol designed for anonymity and security through one-time pads. Each client generates a unique one-time key for encryption per session.

Note: This project was created as a part of term project for Cryptography and is not recommended for production purposes as of now.

ChatOTP Server

This repository contains source code for ChatOTP Server. The backend uses PostgresSQL and REST API controllers for handling user data and files respectively.

Encryption Algorithms

1. Xor Cipher
2. Rc4 Cipher

Note: Rc4 cipher generates a keystream which can be used for encryption by combining it with plaintext using bitwise Xor.

Running the server

1. Change origins of CORS to corresponding domain(s) that your client is hosted on.
2. Create data directory and put docker-compose.yml outside the data directory. The data directory consists of the database.
3. Use docker compose up to auto start the server.
4. You can use docker compose down to stop the server.
