AES-256 PROTECTED

Encryption Architecture & Data Security Details

Technical Resource CZ-702 | Updated April 2026

Security is the bedrock of the CHATZYO experience. Whether you are connecting for a private 1-on-1 video call or browsing our Tamil chat rooms, your data is shielded by military-grade cryptographic protocols. This document provides a clinical breakdown of how we secure real-time media streams and signaling data.

Zero-Access Commitment: Because CHATZYO uses End-to-End Encryption (E2EE) for Peer-to-Peer calls, our servers cannot "see" or "hear" your conversations. The keys required to decrypt your video are stored only on your local device.

1. WebRTC Security Stack

CHATZYO is built on the WebRTC (Web Real-Time Communication) framework, which mandates encryption for all media components. Unlike legacy VoIP systems, WebRTC does not allow unencrypted connections.

DTLS (Datagram Transport Layer Security)

Used to negotiate the secret keys between two peers. It prevents eavesdropping and tampering during the initial connection phase.

SRTP (Secure Real-time Transport Protocol)

Specifically designed to provide encryption, message authentication, and integrity for video and audio data packets.

2. Cryptographic Algorithms

To ensure long-term security against brute-force attacks, we utilize modern cipher suites that are standard for 2026 communications:

Media Encryption: AES-GCM 256-bit (Advanced Encryption Standard with Galois/Counter Mode).
Key Exchange: ECDHE (Elliptic Curve Diffie-Hellman Ephemeral), providing Perfect Forward Secrecy (PFS).
Authentication: HMAC-SHA1 to verify that data packets have not been modified in transit.

3. Peer-to-Peer (P2P) Security Advantages

In our random video chat, whenever a direct path is available between two users, the video stream never touches a central server. This "Direct Tunnel" approach minimizes the attack surface. For users in restricted networks (like those in our USA or UK chat zones using corporate firewalls), we use TURN servers, but the media remains encrypted with keys known only to the two end-users.

4. Signaling Layer Protection

While the video is P2P, the "Signaling" (the process of finding your partner) occurs via our secure servers. This layer is protected by TLS 1.3, the latest and most secure version of the Transport Layer Security protocol. This ensures that metadata—such as which room you are joining—is invisible to external snoopers and ISPs.

Frequently Asked Questions

Does CHATZYO store my encryption keys?
No. Keys are generated "on-the-fly" for every new session and are destroyed the moment you disconnect or refresh the page.

Can a VPN improve this encryption?
A VPN adds an extra layer of privacy by masking your IP address, but it does not change the core AES-256 encryption used for the video stream itself. Both work together to provide maximum security.
