specimen receipts · signer vector set v1 · re-verified in your browser

Check these receipts.

The payout will not clear without a PCRZERO receipt.

Real dual-signed envelopes. Your browser checks both signatures — Ed25519 and ML-DSA-44 — with no account, no key and no network. Nothing here says pass until this tab has.

Frozen at capture, so the same bytes reach every visitor. recorded is a signed field inside the receipt; verify is the one this tab computes, and it stays blank until it has.

provenance

Captured 2026-08-08 from pcrzero-signer/vectors/receipt-vectors-v1.json, the signer’s golden vector set, by scripts/build-specimens.mjs.

These are not production receipts. The signatures are real and they verify; the signing keys, the measurements and the document hashes are deterministic test material generated from seeds that are visible in the signer’s source. No production key signed anything on this page. A receipt for a failed measurement is signed exactly as strongly as one for a pass, which is why one of the specimens below records a fail and still verifies.

Only public keys are published here — 2 key sets, each a key id, an ML-DSA-44 public key and an Ed25519 public key. The verifier is the SDK’s own, vendored under src/scripts/receipt/ with its source path and re-vendor command in the header of each file.
