Check the proof yourself.
Someone sent you a ProofPack, a receipt or a Capsule from Farbaek? Drop it here to see whether it's exactly what was recorded, and what it says was approved, changed and checked.

What can be checked
- ProofPacksWhat was approved, the exact content applied, and the checks that ran.
- Recovery receiptsA change that was undone, file by file.
- Check receiptsA check run in a test space, with its exit codes.
- Security reportsA project's score and every finding.
- Workspace CapsulesA project packed to move, with a BLAKE3 hash for every file.
What a check here does, and doesn't, tell you.
Intact means unchanged
Every record's digest is the SHA-256 of its canonical JSON. Change one character anywhere and the digest no longer matches.
A signature shows who recorded it
A signed ProofPack carries Farbaek's Ed25519 signature. This page checks it against the keys Farbaek publishes. When a record isn't signed, it says so: a match then proves it's unchanged, not who made it.
It stays on your computer
Files you choose are read and hashed in this tab with your browser's own cryptography. Nothing is sent to Farbaek or anyone else.
Proof files come from Farbaek: download one from a ProofPack, or export a whole project with everything it holds. Each file uses an open format, so you can also check it without this page. The ProofPack format, and how to check one with OpenSSL.
