PDFsharp & MigraDoc Forum

Hi,

I would like to add digital signature to my document in the version of 6.0.0-preview-3 but I couldn't find an option for that.
PdfSignatureHandler and PdfSignatureOptions classes are completely missing from this release.
How can I digitally sign my document in 6.0.0?

Thank you for your answer.

So far, those classes were never included with any release of PDFsharp.

Oh, yes, you are right.
In the meantime, I found out that we are using a version that was not included in the official product, unfortunately.
Here is the discussion about this modification: Support of digital signatures #10

Hi,

I started porting the 1.5 pull request #10/#11 you refer to on the new PdfSHarp 6 version and here is the new pull request:
https://github.com/empira/PDFsharp/pull/48

There are minor changes in BouncySigner (it now uses BouncyCastle 2) and in ISigner signature.

It's still draft though: appearance seems to not display well.

Let me know any suggestions.

Digital signature of PDF is now available in this fork package:
https://www.nuget.org/packages/PDFsharp-extended/

With a limitation though: it cannot yet sign already signed documents.

I just want to add a signature field, not the signing itself. How I can achieve that?

See my answer on the pull request.
