Drop a CarveTrace report or evidence bundle to verify its cryptographic integrity. Verification runs entirely in your browser — nothing is uploaded.
Producer public key (optional for self-contained bundles)
Drop a .pem file here, or paste the
-----BEGIN PUBLIC KEY----- PEM block. Bundle ZIPs
include their own verification/public-key.pem ; the
verifier uses that automatically when this field is empty.
🔒 Your file never leaves your browser. No upload. No tracking. Open the network tab to confirm zero requests after page load.
Don't have a file? Try a valid sample bundle or a tampered sample bundle (synthetic proofs bundled with this site).

Verification scope
Failures
Not yet verified by this tool (v0.5 work)
The bundle still contains the underlying data — these checks are deferred to a future verifier release :
- per-TSA-anchor RFC 3161 token validation against the QTSP certificate chain
- Bitcoin OTS anchor cross-check against a public Bitcoin block explorer

This browser verifier currently accepts CarveTrace evidence bundle ZIPs only.
For other files, use the
carvetrace-verify CLI,
which covers the full report + raw-event verification surface.
