How long can we validate the eSignature signed PDF (PAdES-LTV), AFTER downloaded?

LTV (Long Term Validation) have a long expiration date, but it may be NOT forever, so I think we need to take appropriate action after the life-time is exceeded.

The specification of the downloaded PDF seems to be PAdES-LTV.

In PAdES-LTV, I understand that the expiration date of the entire PDF is the expiration date of the last added document timestamp.

When the certificate of document time stamp attached to the downloaded PDF expire?

If it's long enough, I don't have to do anything, so I asked how long it is.

I looked at page 9 of the PAdES-LTV specification (below link) and understood and asked the question as above.

Hi,

In our regular Electronic Signature modality, DocuSign is the one signing the certificate, which is issued by entrust.

When it comes to the "date of the last added document timestamp", this makes reference to the last change performed to the completed documents, whether it is a new document being added or a change to a document in the PDF.

As long as the PDF in question has not been tampered with the certificate will not expire, unless it was completed/created prior to the date in which DocuSign enabled PAdES-LTV, in which case the document must be re-downloaded for it to come with the update to the certificate.

Hi Alejandro,

I'd like to confirm what the statement "In this case, you need to re-download the document to accompany the certificate renewal" mean.

Is it means as follow? :

PDF, completed/created prior to the date in which DocuSign enabled PAdES-LTV, must be re-downloaded for it to come with the update to the certificate.

Or, is it means as follow? :

The PDF will not expire, by re-downloading the document.

Best Regards,

Hi,

The first would be accurate, according to our documentation.

Any document created prior to the date on which we enabled PAdES-LTV must be re-downloaded for PAdES-LTV to come into effect in the PDF
