Somebody handed you a record and a digest. Paste the record here and this will tell you whether it is the one that digest came from. No account, nothing stored, nothing sent anywhere.

This shows the file has not changed since the digest was made. It is not an appraisal, not a certification, and not evidence that anything described here exists or that a photograph was not staged.

How this works

  1. The person who kept the record printed the pages and downloaded the file beside them.
  2. Both came to you together. The pages carry the digest; the file is what the digest was made from.
  3. Paste the file here. If a single character of the record changed, the digest changes with it.

You do not have to trust this page. The digest is the SHA-256 of the file exactly as it was downloaded — any checksum tool gives the same answer.
