Check a record hasn’t changed
Every record has a receipt with its fingerprint, a long code that changes if even one character of the file does. Comparing it with your own copy shows whether the file is exactly as it was filed.
-
Open the record’s receipt
Open the record and choose the Receipt tab. You’ll see the date and time it was filed and its SHA-256 fingerprint.
-
Work out the fingerprint of your copy
On a Mac, open Terminal and type shasum -a 256 followed by the file’s name. On Windows, open Command Prompt and type certutil -hashfile, the file’s name, then SHA256.
-
Compare the two
If your fingerprint matches the one on the receipt, your copy is exactly the file that was filed. If it doesn’t, the file has changed since.
-
Keep the receipt with your copy
Click Download the receipt to save it. The Receipt tab shows a command you can run to check the document against it on your own computer, without needing Folio.
What a match tells you
A match shows the file hasn’t changed since it was filed. It doesn’t say whether the document itself, or any signature on it, is genuine. For signatures, run a signature check in Nib.
If something goes wrong
The receipt says STAMP PENDING. The time-stamp hasn’t come back yet, and it will appear on its own. If it’s still pending a day later, write to us at [email protected].
