Streaming Encrypted Files P2P with WebRTC DataChannels and WebCrypto in TypeScriptsitepoint.com

The tutorial shows how to build a browser‑only P2P file transfer using WebRTC DataChannels, the Streams API, and WebCrypto to encrypt 64 KB chunks on the fly, while applying backpressure via bufferedAmountLowThreshold. This prevents memory blow‑outs and ensures integrity with per‑chunk SHA‑256 verification.
