Hi Team,
I have a few questions about docx digital signatures.
When using MSO Professional Plus 2024 to open a file signed with one of the two examples from the site, the signature panel is not displayed as if there are no signatures. If we add an empty signature line to the document before signing, the panel is there, so is the empty signature line, but the signatures added afterwards with GemBox.Document are missing. I think I had the same problem a while ago with Office 2021, but I didn’t pay attention to it then and ignored it.
How can a signature line be added at any place/paragraph in the document?
If in a 5-page document, we have pre-added two signature lines on each page, how can we sign signature line 2 on page 3. In general, can a pre-added signature line be signed and is there a way to access the pre-added signature lines to verify that they are signed and, if signed, to retrieve information about the certificate it was signed with, as with GemBox.Pdf .
Note that this is a hidden pre-released version, to install it you’ll need to run the above command on the NuGet Package Manager Console (Tools → NuGet Package Manager → Package Manager Console).
Regarding the signature lines, unfortunately, GemBox.Document currently doesn’t provide support for them in signed DOCX.
I created an internal support ticket for this feature and added your report. We’ll keep track of this feature’s priority, and when it increases (more users request it), we’ll start working on it.
Thanks Mario,
Works perfectly with Office 2021 and 2024.
Regarding Signature Lines, it would be nice to actually see it implemented because I’ve found that many users don’t know exactly what a digitally signed file is, and if they don’t see their names, or a picture of the signature, with the infamous X, in a specific place in the file, so it is not signed.
