SuperFile Documentation

Guides and reference for everything SuperFile ships: the public register at superfile.com, SuperSecure files that stay under your control after they leave, and SuperDRM, the licence server you can run on your own infrastructure.

Quick startCreate your account, sign in, reserve your name and protect your first file in ten minutes. Sign in & accountsEmail link, phone, passkey, one-time code, Sign in with sup.

DRM quick startFive calls from nothing to a metered licence. Widevine, FairPlay and Clear Key. API referenceEvery route, field, policy and error code. Security modelWhat is protected, how, and what hardware-secure playback actually means.

#What SuperFile is

SuperFile wraps any file — PDFs, spreadsheets, presentations, images, video, even whole databases — in split-key encryption that travels inside the document. The decryption key is divided, so no single party, SuperFile included, can open a file alone. Authorization is decided when a file is opened, not when it is sent: you can see who opened it, where and when, and revoke access everywhere in one click, downloaded copies included. A protected file keeps its name and gains an s on its extension: report.pdf becomes report.pdfs.

Three products carry that idea today, and this site documents all three.

Product	What it is	Where
SuperFile®	The register: examined @names and .extensions, recorded in waves with permanent registration numbers anyone can check.	superfile.com
SuperSecure®	Seal, share, see and unshare. The vault and viewer for SuperFiles, in beta.	beta.supersecure.com
SuperDRM™	The key and licence service behind the viewer: Widevine, FairPlay and Clear Key licences at $0 per licence, hosted by us or on your premises.	superdrm.com

The family page explains the other marks — SuperChain™, Zero Trust File Encryption™, Sup™ — and what is coming next.
