Zero-Trust Security Model
Complete Security by Design
FlashChat operates on a zero-trust security model where no party, including our servers, can access your conversations.
Our security architecture ensures that messages are encrypted end-to-end using WebRTC technology, providing military-grade protection for your private conversations.
WebRTC End-to-End Encryption
How It Works
FlashChat uses WebRTC (Web Real-Time Communication) to establish direct, encrypted peer-to-peer connections between your browser and your chat partner's browser.
Key Exchange
Browsers negotiate encryption keys using DTLS handshake protocol
Secure Connection
Direct peer-to-peer encrypted data channel established
Encrypted Messaging
All messages encrypted before transmission, decrypted only on recipient's device
Direct P2P Communication
User A
User B
DTLS Encryption Details
