Verify a document

Did you receive a PDF issued by ospais — an expense sheet, a report — and want to be sure it is the original and has not been altered? Drag it here.

The other way: open the PDF and look

Every document issued here carries a digital signature inside. Open it in Adobe Reader, Acrobat or another reader that understands them and a bar appears at the top saying whether the document has been altered since it was signed. That works without this page and without an internet connection.

Note that the reader will say it does not know who signed. It is right: the certificate was issued by ourselves, and a PDF reader only trusts certificates from authorities already on its list. That does not undermine the detection of alterations — that is arithmetic and works regardless. The check above exists to answer exactly that doubt.

What this proves, and what it does not

It proves the document is exactly what the application issued, on that date. It does not prove that what is written in it matches reality: the expenses are the ones the person entered, and that is a matter for whoever disputes them.
