Security & Encryption Architecture
Deep dive into TransitFiles zero-knowledge cryptographic pipeline, hardware-accelerated memory streaming, and ephemeral edge broker mechanisms.
🔒 1. WebRTC DTLS 1.3 Encryption Standard
TransitFiles leverages native browser WebRTC DataChannels. Every peer connection performs an automatic cryptographic handshake using Datagram Transport Layer Security (DTLS 1.3) with ephemeral 256-bit elliptic curve Diffie-Hellman (ECDHE) keys.
This guarantees that only the sender's and receiver's browsers hold the session keys. Man-in-the-middle (MITM) attacks and ISP snooping are mathematically prohibited.
⚡ 2. Direct Memory-to-Memory Chunk Streaming
Traditional cloud uploaders write your file to a server disk before the recipient can download it. In contrast, TransitFiles slices files into 64 KB binary chunks (ArrayBuffers) in the sender's client RAM, transmits them directly over the encrypted SCTP channel, and reconstructs them into a complete Blob directly in the receiver's browser memory.
🌐 3. Ephemeral Edge Signaling
Signaling is handled by stateless Cloudflare Worker Edge nodes. Messages contain only session descriptors (SDP) and ICE network candidates, which are strictly ephemeral, held in memory for under 60 seconds, and never written to permanent disk storage.
🔍 4. Zero Logs & Client Verification
Because the client-side code runs purely in JavaScript and utilizes standard W3C WebRTC APIs, anyone can open browser DevTools to audit network requests and verify that raw file binaries never touch any backend server.
