The Opaque Handbook

Everything you need to get the most out of Opake.

Just getting started?

Set up your cabinet in a few minutes. No prior knowledge of atproto, encryption, or command lines required — you can learn the rest as you go.

Store, share, and recover files with Opake.

Set up your cabinet, create your first encrypted file, and explore the interface.

Share a file with someone else. No account setup on their end, no invite link, just their handle.

Share folders with teams, families, or research groups. Add and remove people without re-uploading files.

Move your identity onto a new phone or laptop without putting it on the network in plaintext.

Twenty-four words that can bring your identity back on any device — the fallback when nothing else is left.

Common problems and the quickest way through them.

Program against Opake. The CLI is the reference implementation; the SDK and React bindings wrap the same primitives for building your own clients.

How Opake protects your data — the crypto, the records, the protocol. Written for anyone curious enough to look, not just developers.
