Pass the Pass 🔐

A sleek, browser-based secure message exchange application that enables end-to-end encrypted communication between peers. This lightweight tool allows users to easily encrypt and decrypt messages using public-key cryptography, all while keeping your sensitive data secure.

Features ✨

• End-to-End Encryption: Secure message encryption using public-key cryptography
• No Server Storage: All encryption happens in your browser - no messages are stored on any server
• Simple Interface: Clean, intuitive UI for both sending and receiving encrypted messages
• Copy with One Click: Easy-to-use copy buttons for sharing encrypted content
• Mobile-Friendly: Responsive design that works great on both desktop and mobile devices

How It Works 🛠️

1. To Send a Message:

   • Click "I want to send text"
   • Enter your message
   • Configure the recipient's public key
   • Encrypt your message
   • Copy and share the encrypted text

2. To Read a Message:

   • Click "I want to read encrypted text"
   • Paste the encrypted message
   • Use your private key to decrypt
   • Read the original message

Getting Started 🚀

1. Clone this repository
2. Open index.html in your web browser
3. No installation or setup required!

Technologies Used 💻

• HTML/CSS/JavaScript
• OpenPGP.js v6.1.0 for cryptographic operations

Security Notes 🛡️

• All cryptographic operations are performed locally in your browser
• Your private keys never leave your device
• Uses OpenPGP.js with modern cryptographic standards:
  • RSA-4096 or Ed25519 for key pairs
  • AES-256 for symmetric encryption
  • SHA-256 for hashing
• Open-source and auditable code

Recommendations for Maximum Security

• Use Incognito/Private browsing mode to ensure no data persists
• Disable browser extensions when using this tool to prevent potential data access
• Clear browser data after use if not using Incognito mode
• Verify the recipient's public key through a secure channel
• Optional: Public keys can be saved in browser storage for convenience, but this reduces privacy
• Generate your keys using trusted tools like GPG or Kleopatra - do not use online key generators
• JavaScript is required and must be enabled - the app won't work without it as all cryptographic operations are JavaScript-based
