Verify an LSRI export

Recompute the SHA-256 fingerprint of a Committee or Proof export payload and compare it with the fingerprint printed in the PDF.

SHA-256 Client-side No upload

Verification input

Paste the canonical export payload JSON. The calculation runs locally in your browser; no data is sent to LSRI.

Export type

Payload JSON

Hash printed in PDF (optional)

Paste a JSON payload and calculate.

The verifier wraps the payload as {version, kind, payload}, sorts object keys recursively, then computes SHA-256 over the canonical JSON string.
