Why Privy? 🤔

In today's digital age, privacy isn't just a feature – it's a necessity. Traditional messaging platforms store your data, creating potential security vulnerabilities. Privy solves this by implementing true ephemeral messaging where nothing is ever written to disk. 🛡️

Key Features ⭐

1. Zero Storage Architecture 💨: All communications exist purely in RAM with immediate secure memory wiping after delivery. No logs, no history, no traces.

2. Modern Cryptography 🔒: Implements RSA-OAEP encryption using Web Crypto API with 2048-bit keys and SHA-256 hashing for secure communication.

3. Complete Anonymity 🕵️: No user accounts and no metadata collection ensure your identity remains protected.

4. Real-time Encrypted Rooms 🚪: Create secure, ephemeral spaces for group communications with secure message destruction.

Technical Details 🔧

Privy uses the Web Crypto API for cryptographic operations:

const generateKeyPair = async (): Promise<CryptoKeyPair> => {
  return await window.crypto.subtle.generateKey(
    {
      name: 'RSA-OAEP',
      modulusLength: 2048,
      publicExponent: new Uint8Array([1, 0, 1]),
      hash: 'SHA-256'
    },
    true,
    ['encrypt', 'decrypt']
  );
};
