Technologies Used

• Rust: The primary programming language for the backend.
• Axum: A lightweight and ergonomic web framework for building APIs in Rust.
• SQLx: An asynchronous, compile-time verified SQL crate supporting multiple databases (in this case, PostgreSQL).
• Argon2: A secure password hashing library.
• jsonwebtoken: A library for encoding and decoding JSON Web Tokens (JWT) for authentication.
• dotenv: For managing environment variables in development.
• Tokio: An asynchronous runtime for Rust, powering the non-blocking operations.
• Axum-Extra: Additional utilities for Axum, including cookie support.
• Tokio-Cron-Scheduler: A scheduler library for running tasks periodically based on cron-like expressions.
• Tower & Tower-HTTP: Middleware and utilities for building robust HTTP services, including CORS and tracing support.
• Serde & Serde JSON: A framework for serializing and deserializing Rust data structures efficiently, used with JSON data.
• Validator: A validation framework for input validation in Rust.
• Chrono: A date and time library, used with serde for working with time formats.
• UUID: A library for generating and parsing universally unique identifiers (UUIDs).
• Tracing Subscriber: A logging library for Rust applications, providing structured logging.
• AES & Block Modes: Libraries for Advanced Encryption Standard (AES) encryption.
• RSA: A library for RSA encryption and decryption.
• Rand: A library for generating random values, used in cryptography and token generation.
• Base64: A library for encoding and decoding Base64, often used in file and cryptographic operations.

Technologies Used

• Rust: The primary programming language for the backend.
• Actix Web: A powerful, pragmatic, and extremely fast web framework for Rust.
• SQLx: An asynchronous, compile-time verified SQL crate.
• Argon2: Password hashing library for secure user authentication.

• dotenv: To manage environment variables.

Getting Started

To get a local copy of this project up and running, follow these steps:

Prerequisites

• Rust (1.58 or newer) installed. You can install Rust using rustup.
• PostgreSQL installed and running. Ensure you have a database created for this project.

Installation

1. Clone the repository:

git clone https://github.com/AarambhDevHub/file-share-rust-backend.git cd file-share-rust-backend 2. Create a .env file in the root of the project with the following variables:

```
# -----------------------------------------------------------------------------
# Database (PostgreSQL)
# -----------------------------------------------------------------------------
DATABASE_URL=postgresql://username:password@localhost:5432/file_share_tutorial

# -----------------------------------------------------------------------------
# JSON Web Token Credentials
# -----------------------------------------------------------------------------
JWT_SECRET_KEY=my_ultra_secure_jwt_secret_key
JWT_MAXAGE=60
```

1. Install the necessary dependencies:

   cargo build

2. Run database migrations:

   sqlx migrate run

3. Start the server

   cargo run

API Endpoints

• POST /api/auth/register: Register a new user.
• POST /api/auth/login: Login a user and return a JWT token.
• GET /api/users/me: Retrieve the authenticated user's information.
• PUT /api/users/name: Update the authenticated user's name.
• PUT /api/users/password: Change the authenticated user's password.
• GET /api/users/search-emails: Search for users by their email addresses.
• POST /api/file/upload: Upload a file (requires authentication).
• GET /api/file/retrieve: Retrieve an uploaded file by ID (requires authentication).
• POST /api/list/send: Send a list of files to another user.
• GET /api/list/receive: Retrieve the list of files received from another user.
