End-to-end encrypted video

End-to-end encrypted video. Zero-knowledge by design.

A single breach can expose every video on your platform. BlindCast encrypts video in the browser before upload — your server never sees plaintext. E2EE video encryption for platforms that take security seriously.

How it works

How end-to-end video encryption works

01

Encrypt

Video is end-to-end encrypted in the browser — not on your server — before it ever leaves the client. Plays on any standard HLS player, no plugins required.

02

Stream

Encrypted video flows through any standard CDN or storage. Your infrastructure handles ciphertext only.

03

Decrypt

Only viewers with authorized keys can decrypt and play. Zero-knowledge means zero server exposure.

Beyond traditional DRM

Production-ready E2EE video encryption

End-to-end encrypted video is hard to get right. Shipping it in production — across every device, every edge case, every compliance requirement — is harder. We already built both.

Drop-in SDKs

Web, iOS, and Android. Encrypt on upload, decrypt on playback — a few lines of code.

Adaptive bitrate streaming

Safari, Chrome, Android, iOS — each handles encrypted HLS differently. Our SDKs handle quality switching seamlessly on all of them.

Key management & rotation

Revoke access to individual videos without re-encrypting. Rotate keys without downtime. Manage viewer permissions with time-bounded leases.

Offline download & playback

Encrypted downloads that work without network access, with proper license management built in.

Admin dashboard & audit logs

Content management, access control, and full audit trail — who watched what, when, from where.

HIPAA & compliance-ready

Built for healthcare, legal, and enterprise. Zero-knowledge architecture means compliance by design.

FAQ

Frequently asked questions

What is zero-knowledge video encryption?
Zero-knowledge video encryption means your video is encrypted on the client — in the browser or native app — before it ever reaches your server. Your infrastructure only stores and serves opaque ciphertext. Even if your server is compromised, no plaintext video is exposed.
How is E2EE video encryption different from traditional DRM?
Traditional DRM systems decrypt content on a trusted server or rely on proprietary browser plugins. BlindCast uses end-to-end encryption (E2EE) — encrypting and decrypting entirely on the client side using standard Web Crypto APIs and HLS-compatible AES-128 encryption. There are no plugins, no vendor lock-in, and your server never handles plaintext video.
Is end-to-end encrypted video secure enough for healthcare and legal?
Yes. BlindCast's zero-knowledge E2EE architecture is compliance-ready by design. Because your server never sees plaintext video, you reduce your compliance surface area for HIPAA, SOC 2, and other regulatory frameworks. Video encryption happens before upload and decryption happens only on authorized viewers' devices.
Does BlindCast work with my existing CDN and infrastructure?
BlindCast is infrastructure-agnostic. Encrypted video is standard HLS — it flows through any CDN, object store, or media server without modification. You keep your existing stack and add client-side encryption on top.
What platforms does BlindCast support?
BlindCast supports Web (any modern browser), iOS via AVPlayer, and Android via ExoPlayer. Encrypted HLS streams play natively on all platforms — no custom player required.
