## Introduction

**VeriDoc** is a secure, scalable document verification system designed to verify the integrity of files using advanced cryptographic algorithms. It employs digital signatures, SHA-256, and RSA algorithms to ensure data authenticity and integrity. 

- **Backend**: Built with Python for cryptographic operations and API management.  

- **Frontend**: Developed using Next.js with Tailwind CSS and Redux Toolkit for state management.  

- **Storage and Authentication**: Utilizes Firebase for file storage and user authentication.  

- **Deployment**: Docker ensures seamless scalability and deployment.

## Features

### **Core Features**

- **Secure File Upload**: Users can upload files securely to Firebase.  

- **Cryptographic Verification**: Ensures document integrity using SHA-256 hashing and RSA-based digital signatures.  

- **File Integrity Check**: Compares uploaded files to detect any alterations.  

- **File Reference and Comparison**: Allows users to upload a new file and compare it against previously stored versions.  

- **User Authentication**: Secure login and registration via Firebase Authentication.  

### **Cryptographic Operations**

- **Signing**: Creates a digital signature for the provided message.  

- **Hashing**: Generates a SHA-256 hash of the data.  

- **Verification**: Validates data integrity using the hash and digital signature.  

### **Deployment**  

- **Dockerized Deployment**: Streamlined deployment and enhanced scalability using Docker.

## API Endpoints

- **POST `/api/extract-text-from-pdf`**  

  Extracts text from a PDF file.

- **POST `/api/sign`**  

  Signs a message. Takes an input message and returns:  

  - Message  

  - Message Hash  

  - Public Key  

  - Digital Signature  

- **POST `/api/verify`**  

  Verifies the integrity of a message by comparing its hash with the digital signature.  

  - Returns: `true` if valid, otherwise `false`.  

- **POST `/api/hash`**  

  Hashes the provided data using SHA-256 and returns the hash value.
