Safe is a secure and full-stack password manager that allows users to store and retrieve encrypted website credentials. Built with MongoDB, Node.js, React, and Express, it prioritizes strong data security and a seamless user experience.

• ReactJS
• TailwindCSS

• Node.js
• Express.js
• MongoDB (Database)
• Crypto (AES-256-CTR encryption)
• Bcrypt (for hashing credentials)
• JWT (Authentication)

• 🔐 Cryptographically secure storage of website passwords
• 🔑 AES-256-CTR encryption for sensitive data
• 🧠 Passwords are encrypted before storage and decrypted only when requested
• 📄 Add a website and its password securely
• 👁️ Click on a website to reveal its decrypted password
• 🔒 JWT-based session management
• 🎨 Intuitive and responsive UI using React and TailwindCSS

• AES-256-CTR encryption ensures passwords are securely encrypted using the crypto module before being stored in MongoDB.
• Bcrypt is used to hash user authentication data (e.g., login system).
• JWT ensures secure user sessions.
• Passwords are never stored in plaintext, and decryption happens only on authenticated requests.

1. User adds a website and password

   • Password is encrypted with AES-256-CTR using Node's crypto library.
   • Encrypted data is saved to the MongoDB database.

2. User clicks on a website name

   • The encrypted password is fetched.
   • The backend decrypts it and sends the plaintext password securely to the frontend.

3. Authentication and session handling

   • JWT is used to manage and protect authenticated sessions.

• ✅ Developed a secure, full-stack password manager using MERN stack
• 🔐 Prioritized data security using AES-256-CTR encryption via the crypto module
• 🛡️ Strengthened protection against vulnerabilities through cryptographic best practices
• 🎯 Designed a clean and intuitive UI with React & TailwindCSS for a smooth user experience
