Auditor utility · tamper detection

Verify any EvalGuard compliance document. 

Paste an Annex IV, SoA, audit bundle, or evidence row. We recompute the canonical SHA-256 hash and tell you if it matches the embedded claim. No data stored.

Tamper detection

How this works

  1. Server reads the document you paste.
  2. The hash field (default: snapshotHash) is removed.
  3. Remaining fields are canonicalized — keys sorted recursively, JSON.stringify-ed.
  4. SHA-256 of canonical JSON is compared to the claimed hash.
  5. No data is stored or logged. Pure function-as-a-service. Same input always returns same output.
