Authentication_app

Overview

This project implements a robust authentication system using both secret key authentication and RSA public-key cryptography. It is designed to provide secure communication between clients and servers, ensuring data integrity and confidentiality.

Features

1. Secret Key Authentication: Utilizes symmetric encryption to authenticate users with a shared secret key, ensuring that only authorized users can access the system.
2. RSA Authentication: Implements asymmetric encryption using RSA keys to securely exchange messages and verify identities without requiring a shared secret.
3. Secure Data Transmission: Protects sensitive information during transmission using industry-standard cryptographic algorithms.
4. Modular Design: The code is organized into modules for easy maintenance and extensibility.

Getting Started

RSA-Based JWTs

1. Check Key Existence: Use the key_existance function to determine whether RSA public and private keys already exist.
2. Read Existing Keys: If keys are found, the read_keys function will read and load them for use.
3. Generate New Keys: If no keys exist, the generate_jwt function will create new RSA keys.
4. Save Keys: After generatig or reading keys, you can save them using the save_keys function for future use.
5. Verify Keys: To validate any public key, use the verify_jwt function.

Secret Key-Based JWTs

If you prefer to use a secret key instead of RSA, you can utilize the following:

1. Generate JWT: Use the generate_jwt function under the jwt_secret module to create a JWT.
2. Verify JWT: Use the verify_jwt function under the jwt_secret module to validate a secret-based JWT.
