Evidence verifier

Check a recording hasn't been changed

Drop a Vocert evidence package (the .zip from an export, or its manifest.json) below. It's verified entirely in your browser — the hash-chain and signature checks make no network requests, so you don't have to trust Vocert's servers, or even your internet connection.

…or paste the JSON

🔒 Signatures are verified only against Vocert's published key (2E5+/GTNvDuasKtsGyzo+xbXdsWXvTnjwYU3j+WjmXk=) — never the key embedded in the uploaded file.

This is a technical integrity check, not legal advice.
