I'm building a web application that most allow the user to digitally sign PDF documents with certificates installed in the client machine.
The document, once signed, should be posted back to the server, where it will store the signed version.
The server is running Classic ASP/ASP.NET
Where should I go?
Now you can sign PDF documents right from your Chrome Browser Preview Page. Simply click on the „Sign“ icon that appears in the lower right corner of your PDF Preview to sign any PDF document without leaving the page.
Windows: Use Adobe Reader To sign a document using Adobe Reader, first open the PDF document in the Adobe Acrobat Reader DC application. Click the “Fill & Sign” button in the right pane. Click the “Sign” button on the toolbar and select “Add Signature” to add your signature to Adobe Acrobat Reader DC.
I actually built a system just like this into our web application. Here are some links I found tremendously helpful in doing so:
