The system allows users to securely store and access their files while ensuring data integrity, confidentiality, and authenticity.\n\n## System Architecture\n\n![evault](https://github.com/sanjay-sol/commitzz/assets/114111046/c23ef5f4-9063-4d98-92c0-e67cd834799e)\n\n## Features\n- **User Authentication:** Users can log in using their MetaMask wallet address, ensuring secure access to the platform.\n- **File Upload:** Users can upload files to the vault system, initiating the encryption process.\n- **Encryption:** Uploaded files are encrypted using the AES-256 symmetric encryption algorithm for confidentiality.\n- **Key Distribution:** The symmetric encryption key is divided using Shamir's Secret Sharing scheme and distributed to designated entities for secure storage.\n- **Digital Signatures:** A signature is generated using the user's MetaMask private key to authenticate the file and its contents.\n- **Access Control:** Users can specify access control settings, such as public or private, to regulate access to their files.\n- **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.\n- **File Retrieval:** Users can retrieve the required key parts from authorized entities to reconstruct the symmetric key for decryption.\n- **Data Integrity Check:** Users can verify the integrity of the file by comparing its hash stored on the blockchain with the recalculated hash.\n- **Authentication:** The authenticity of the file is verified using the digital signature and the user's MetaMask public key stored on the blockchain.\n\n## Installation\n1. Clone the repository:\n``` \ngit clone https://github.com/sanjay-sol/shamirs\n```\n2. Install dependencies:\n```\nnpm Install\n\nNote: Have Metamask installed\n```\n\n## Pinata Setup\n```\nget pinata credentials from https://www.pinata.cloud/\n\nAPI_KEY = \"pwx...\"\nAPI_SECRET = \"Qmcisewr34.....\"\n```\n\n## Usage\n1. Start the application:\n```\nnpm run dev\n```\n2. Access the application at http://localhost:3000 in your web browser.\n\n\n## Contact\nFor any inquiries or feedback, please contact [email](mailto:sanjaysirangi@gmail.com).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsanjay-sol%2Fshamirs","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsanjay-sol%2Fshamirs","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsanjay-sol%2Fshamirs/lists"}
