Verify it yourself
Don’t take our word for it. Check the record.
Every RTI turnover package carries a verification file — its full SHA-256 chain. Drop it below and this page recomputes every hash right in your browser. Nothing is uploaded, and the same check runs offline with a free, open tool. If a record was altered after it was sealed, the break is detectable, permanent, and dated.
Verify a package
Everything above runs in your browser with the Web Crypto API. The file is read locally and never sent anywhere. The identical check is available as a command-line tool and an offline page, so a record can be confirmed years from now without RTI.
Tamper evident record
Every record is chained. Nothing edits quietly.

Chain break
RTI-0412 was altered after signing. Its stored prev-hash no longer matches RTI-0411.
What the check proves — and what it doesn’t.
The chain holds
Each record hashes the one before it. Recompute every hash and, if any record was changed after it was sealed, the match fails. That failure is what you see.
Tamper-evident, not tamper-proof
The chain does not stop someone from editing a record. It makes the edit detectable, permanent, and dated. We never claim more than that.
