ASP.NET Web Forms samples project

The ASP.NET Web Forms samples project shows how to use Rest PKI together with Web PKI on a project using ASP.NET Web Forms. It is hosted on GitHub at:

https://github.com/LacunaSoftware/RestPkiSamples/tree/master/CSharp/WebForms

Running the project

  1. Download the project or clone the repository
  2. Open the project folder (CSharp\WebForms)
  3. Open the solution file (.sln) on Visual Studio
  4. Generate an API access token on the REST PKI website
  5. Paste your access token on the file web.config
  6. Run the solution. Make sure your system allows automatic Nuget package restore (if it doesn't, manually restore the packages).

Project map

This section lists where to find the relevant parts in each feature sample on the project.

Authentication with digital certificate

PAdES signature with file already on server

PAdES signature with file uploaded by user

After the file upload (which is crudely implemented merely for demonstration purposes on the Web Form Upload.aspx and on its code-behind Upload.aspx.cs) is done the control flow is the same as in the sample PAdES signature with file already on server, but with the URL parameter userfile filled.

PAdES co-signature

After the control flow of the sample PAdES signature with file already on server is completed and the link Co-sign with another certificate is clicked, the same control flow is repeated, but now with the URL parameter userfile filled.

PAdES marks

This feature is demonstrated as an optional configuration on the PAdES signature with file already on server sample which by default starts commented out. To enable it, uncomment the following line on PadesSignatureController:

signatureStarter.PdfMarks.Add(PadesVisualElements.GetPdfMark(1));
Tip

Try changing the argument to the GetPdfMark(int) method to see different PDF mark configurations

The relevant code is on the class PadesVisualElements, method GetPdfMark(int).

PAdES signature using server key

PAdES signature without client communication

Open/validate an existing PAdES signature

Not yet available on this project.

Printer-friendly version

After the control flow of the sample PAdES signature with the file already on server is completed and the link Download a printer-friendly version of the signed file is clicked, the flow goes to the web form: PrinterFriendlyVersion.aspx and to its code behind PrinterFriendlyVersion.aspx.cs with the URL parameter file filled.

The generated PDF contains links to the web form: Check.aspx and to its code behind Check.aspx.cs, which shows details of the signatures.

CAdES signature with file already on server

CAdES signature with file uploaded by user

After the file upload (which is crudely implemented merely for demonstration purposes on the Web Form Upload.aspx and on its code-behind Upload.aspx.cs) is done the control flow is the same as in the sample CAdES signature with file already on server, but with the URL parameter userfile filled.

CAdES co-signature

After the control flow of the sample CAdES signature with file already on server is completed and the link Co-sign with another certificate is clicked, the same control flow is repeated, but now with the URL parameter cmsfile filled.
