# Secure Vault System on Blockchain
## Overview
This project aims to develop a secure vault system leveraging blockchain technology and cryptographic techniques. The system allows users to securely store and access their files while ensuring data integrity, confidentiality, and authenticity.
## System Architecture
## Features
- **User Authentication:** Users can log in using their MetaMask wallet address, ensuring secure access to the platform.
- **File Upload:** Users can upload files to the vault system, initiating the encryption process.
- **Encryption:** Uploaded files are encrypted using the AES-256 symmetric encryption algorithm for confidentiality.
- **Key Distribution:** The symmetric encryption key is divided using Shamir's Secret Sharing scheme and distributed to designated entities for secure storage.
- **Digital Signatures:** A signature is generated using the user's MetaMask private key to authenticate the file and its contents.
- **Access Control:** Users can specify access control settings, such as public or private, to regulate access to their files.
- **Blockchain Storage:** File metadata, including filename, size, file hash, Shamir's Secret Sharing parameters, access control settings, timestamp, user public key, and signature, are stored on the blockchain.
- **File Retrieval:** Users can retrieve the required key parts from authorized entities to reconstruct the symmetric key for decryption.
- **Data Integrity Check:** Users can verify the integrity of the file by comparing its hash stored on the blockchain with the recalculated hash.
- **Authentication:** The authenticity of the file is verified using the digital signature and the user's MetaMask public key stored on the blockchain.
