BurnerDocs SHA-256
Choose a file and this page computes its SHA-256 in your browser. The file is never uploaded and never leaves your device.
The hashing is done by demo-hasher.wasm — 2.6 KB of hand-written C
compiled to WebAssembly, running in a Web Worker. It contains no third-party code, not
even a C standard library.

This page ships with a signed release manifest at
/.well-known/provenance-manifest.json listing every file we published
and its SHA-256. The button below fetches the WebAssembly module your browser just
downloaded, hashes it with that same module, and compares the result to what
the manifest claims.
If the manifest cannot be read, this reports that it could not be read. It never reports a pass it did not compute.
