About the format
A .p7s file is a PDF (or another document) with a digital signature wrapped around it. Brazilian notary offices, courts and registries send them all the time, usually named something like “document.pdf.p7s”, and they are signed with ICP-Brasil certificates. Some .p7s files hold only the signature, and the PDF comes as a separate file. Technically it is a CAdES/CMS signature (RFC 5652).
Questions people ask
Why won’t my phone open a .p7s file?
Phones and PDF readers don’t recognize the signature wrapped around the document. We remove that wrapper in your browser and show you the PDF inside.
Is my document uploaded anywhere?
No. The code runs on your own device and reads the file there. You can even switch off your connection after the page loads and it keeps working.
Is this a legal validation of the signature?
It checks that the document hasn’t been changed and that the certificate comes from ICP-Brasil or an authority recognized in the EU. If you need an official validation report in Brazil, use the ITI validator at validar.iti.gov.br.
Is the PDF I download still signed?
Not by itself. The signature belongs to the .p7s file, and the PDF is the document that was inside it. Keep the original .p7s if you may have to prove who signed. The “PDF with signature report” download adds a page that records who signed, when, and what the check found.
What does “Certificate not recognized” mean?
It’s about who issued the certificate, not about the document. The certificate doesn’t come from an authority on the EU trusted lists or the ICP-Brasil list, which are the ones we check. That happens with company, test or very old certificates. Whether the document changed after signing is shown on its own line, just above.
What if the file has more than one signature?
Each signature gets its own card with the signer’s name, the signing time and the result of its own check.
