## Description

NSS Communicator lets you post encrypted messages as comments on YouTube, Twitter/X, Facebook, Reddit, Craigslist, forums — anywhere text goes. Other NSS users decrypt the message. Everyone else sees noise.

<strong>How It Works:</strong>
• Generate an RSA-4096 keypair protected by a passphrase
• Share your .nss public key with contacts
• Import their public keys into the extension
• Compose encrypted messages and copy them to your clipboard
• Paste anywhere — comments, posts, forums, emails
• Recipients paste the encrypted text into NSS to decrypt

<strong>Security:</strong>
• RSA-4096 + AES-256-GCM hybrid encryption
• RSASSA-PKCS1-v1_5 digital signatures
• PBKDF2 (100K iterations) passphrase protection
• Web Crypto API — zero external crypto dependencies
• Private keys never leave your browser
• No servers, no accounts, no tracking
