SecureShare

This repo consists of my Cryptography course project which involves safe transfer of files between users using cryptographic encryptions.

Features

• User Authentication: Users can register and log in securely.
• File Encryption: All files are encrypted using AES (Advanced Encryption Standard).
• Secure Key Exchange: Utilizes RSA (Rivest-Shamir-Adleman) for secure key exchange between users.
• User Interface: A simple and intuitive interface for sending and receiving messages.

Code Flow

1. User Registration and Login:

   • Users can create an account, which securely stores their credentials.
   • Upon login, the system verifies the user's identity.

2. File Sending:

   • When a user sends a file, the application encrypts the file using the recipient's public key.
   • The encrypted file is then sent over the network.

3. File Receiving:

   • The recipient receives the encrypted file and uses their private key to decrypt it.
   • The decrypted file is made available for download in the user interface.

4. Key Management:

   • The application manages public and private keys for each user, ensuring that keys are stored securely.

Installation

To set up the project locally, follow these steps:

1. Clone the repository:

2. Navigate to the project directory:

   cd SecureShare

3. Install the required dependencies:

   npm i

Usage

To run the application, execute:

node app.py

.env

JWT_SECRET=<secret_key>
MONGO_URI=<mongoDb-connection-url>
