Tutorial & How It Works

Comprehensive guide to Voysd's zero-knowledge P2P messaging architecture.

1. Peer-to-Peer WebRTC Tunnels

Unlike legacy messaging platforms that relay your messages through centralized servers, Voysd connects your device directly to your peer using WebRTC DataChannels. Your conversations flow through an encrypted peer-to-peer tunnel established between browsers.

2. WebCrypto ECDH + AES-GCM-256 Key Exchange

When initiating a connection line:

  1. Your browser generates an Elliptic Curve Diffie-Hellman (ECDH P-256) key pair locally using native WebCrypto APIs.
  2. Your public key is encoded inside a connection token that you share with your peer.
  3. Once your peer imports your token and returns their answer token, both clients derive a matching 256-bit symmetric AES-GCM key.
  4. All messages, audio, and video payloads are encrypted and decrypted strictly on your device.

3. Dual-Mode Fallback Messaging

If a direct P2P stream drops or your contact is temporarily offline, Voysd automatically switches to Mode B: Quick Msg Fallback. Messages are buffered inside a transient database queue and are immediately deleted upon delivery, ensuring zero database footprint.

4. 24-Hour Contact Stories

Share quick 280-character status updates or YouTube video embeds with your confirmed contacts. Stories automatically expire and self-destruct after 24 hours. Accounts can post up to 5 stories per day, and any story with 3 community reports is automatically masked.

About Voysd & Parent Organization XelDust

Voysd - Secure Messenger is a serverless, zero-knowledge peer-to-peer communication platform engineered to provide sovereign digital privacy. Operating entirely client-side within browser memory, Voysd utilizes native WebCrypto APIs (ECDH P-256 key exchange and AES-GCM-256 symmetric ciphers) paired with direct WebRTC data channels, ensuring that live messages, file transfers, and audio/video calls pass directly between peer devices without central database logging.

Voysd is engineered and published under its parent organization, XelDust, led by Founder & Managing Director Janith Anjana. Dedicated to building decentralized, privacy-centric software architectures, XelDust empowers users globally with tools that eliminate server-side data harvesting, surveillance, and central metadata tracking.
