PhenixID Signing Services and PDF files compliancy

About

This document describes which PDF files can be signing by PhenixID Signing Services.

It also describes the behaviour when signing PDF with document extensions, such as interactive form fields.

PDF versions

All PDF files from version 1.3 and above are supported.

View this link for more information about PDF versions.

PDF ISO formats

PDFs may adher to ISO formats such as PDF/A, PDF/UA or PDF/X.

All ISO formats that supports electronic signatures (PDF formats PDF/X and PDF/VT do not) are supported by PhenixID Signing Services.

PDF Document properties

The PDF document must allow signing.

Encrypted / password-protected documents

Using PADESSignValve only

If PhenixID Signing Services is configured to use PADESSignValve (without a leading AddImageToPDFValve), the encrypted / protected document must have Signing = Allowed (see above)

Using AddImageToPDFValve or PADESSignVisibleSignatureValve

Usage of these valves requires editing (change) of the document, hence they cannot be applied on encrypted / password-protected PDF documents.

Signing PDFs with document extensions

PDFs with document extension features, such as interactive form fields, can be signed.

After the document has been signed, the document extensions will not be available. An informative message will be displayed when opening the signed document in Adobe Reader.

Based on the extension enabled on the original document, the top panel will display additional information (besides the signature status).
