BlindCast is a drop-in platform for zero-knowledge encrypted video. Unlike standard HLS encryption — where your server generates keys, encrypts segments, and has full access to plaintext — BlindCast encrypts on the creator’s device and decrypts only in the viewer’s browser. Your server never touches plaintext or key material. You get everything you need to ship this in production: player SDKs, upload encryption, key management, and a production-ready server — so you’re not spending months building video infrastructure from scratch.Documentation Index

What you get
Player
Drop-in encrypted HLS playback for any web app. Single import, attach to a video element, point at your key server. 10 lines of code.
CLI
One command-line tool for everything server-side. Generate keys, encrypt HLS segments, upload to S3, and run a local dev server.
npx @blindcast/cli.Uploader
Browser-side upload SDK for web apps where end users upload video. Encrypts in the browser, uploads to S3 via presigned URLs. One function call.
Key Server
Reference key server as a Docker image. Pull, configure, run. Handles key derivation, authentication, leases, and presigned URLs.
How it fits together
- Creator side: The CLI (server-side) or Uploader (browser-side) encrypts HLS segments and uploads them to S3.
- Key Server: Derives per-content encryption keys from a single master key. Authenticates viewers before issuing keys.
- Viewer side: The Player fetches the manifest from your CDN, gets the content key from the key server, and decrypts each segment in the browser.
