OFFLINE RECEIPT VERIFICATION
Verify a chain-of-custody receipt.
A cloak-redact receipt is self-contained — the signing key is inside the signed bytes, so
anyone can confirm it is authentic and untampered without contacting a server. This page
runs the exact same check, entirely on your device. Paste a receipt, or drop the .json file.
The verdict will appear here. Nothing you paste is uploaded — verification is a local cryptographic check.
