Hello,

I try to read PDF files with digital signature and the result is blank string. If i try other PDF without digital signature everything is ok. Is there some restriction with that kind of files? What I can do? Please help!

Extract/Read digital signatures from PDF

I resolved to doing something similar. I used the Spire.PDF nuget package to write myself some C# code which I turned into an activity. I’ll release the activity on the marketplace once it’s somehow production ready, but if anyone’s interested, I basically used this code: https://www.e-iceblue.com/Tutorials/Spire.PDF/Spire.PDF-Program-Guide/Get-and-Verify-Digital-Signature-in-PDF-with-C-Code.html

Hi

Thank you! I saw this post before i wrote my post, but this is for verifying digital signature. I don’t need to verifying or read digital signature. I just need to read the TEXT in the PDF file. If there is any other suggestions
