Your infrastructure should never see your content
BlindCast encrypts video in the browser before upload. Your CDN, storage, and servers never touch plaintext. Built on Web Crypto API and open standards.
How it works
Three steps to zero knowledge
Encrypt
Video content is encrypted in the browser before it ever leaves the client. AES-128-CBC for HLS delivery, AES-256-GCM for storage.
Stream
Encrypted video flows through any standard CDN or storage. Your infrastructure handles ciphertext only.
Decrypt
Only viewers with authorized keys can decrypt and play. Zero-knowledge means zero exposure.
Security-first
Built for regulated industries
Healthcare, legal, journalism, and enterprise teams trust BlindCast to keep sensitive video content truly private.
HIPAA-Ready
Designed for healthcare video workflows where compliance is non-negotiable.
End-to-End Encrypted
Content is encrypted client-side and decrypted client-side. Nothing in between.
Zero-Knowledge
Your servers, CDN, and storage never access plaintext video content.
Web Crypto API
Built on browser-native cryptography. No third-party crypto dependencies.
AES Encryption
AES-128-CBC for HLS streaming (spec-required), AES-256-GCM for storage and key wrapping.
Open Standards
No vendor lock-in. Built on W3C and IETF standards you already trust.
