Home / Verify

Do not trust us. Check.

A passport is worth exactly as much as the ability to verify it without our permission. This page loads the published issuer key, recomputes the canonical form of the record and checks the signature in your browser. No request reaches LENTRA. If the company disappeared tomorrow, every passport it ever issued would still verify.

Verdict

Awaiting input.

Paste a record, or verify the specimen.

The check runs locally. Reload this page offline and it still works.

What is actually checked

Signature

Ed25519 over the canonical record, against the issuer key published at /keys/issuers.json.

Integrity

Any edit to any field breaks the signature. There is no partial pass.

Attribution

The claimed agent next to the network it actually came from: the claim and the evidence, side by side.

Terms in force

The robots.txt state and reserved uses pinned to the moment of the visit, travelling with the record itself.
