It is hosted on GitHub at: https://github.com/LacunaSoftware/RestPkiSamples/tree/master/CSharp/WebForms ## Running the project 1. [Download the project](https://github.com/LacunaSoftware/RestPkiSamples/archive/master.zip) or clone the [repository](https://github.com/LacunaSoftware/RestPkiSamples.git) 1. Open the project folder (`CSharp\WebForms`) 1. Open the solution file (.sln) on Visual Studio 1. 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 * Web Forms: * [Authentication.aspx](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/Authentication.aspx) * [Authentication.aspx.cs](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/Authentication.aspx.cs) * [AuthenticationSuccess.aspx](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/AuthenticationSuccess.aspx) * [AuthenticationSuccess.aspx.cs](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/AuthenticationSuccess.aspx.cs) * [AuthenticationFail.aspx](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/AuthenticationFail.aspx) * [AuthenticationFail.aspx.cs](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/AuthenticationFail.aspx.cs) * JavaScript: [signature-form.js](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/Scripts/signature-form.js) ### PAdES signature with file already on server * Web Forms: * [PadesSignature.aspx](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/PadesSignature.aspx) * [PadesSignature.aspx.cs](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/PadesSignature.aspx.cs) * [PadesSignatureInfo.aspx](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/PadesSignatureInfo.aspx) * [PadesSignatureInfo.aspx.cs](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/PadesSignatureInfo.aspx.cs) * JavaScript: [signature-form.js](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/Scripts/signature-form.js) ### 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](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/Upload.aspx) and on its code-behind [Upload.aspx.cs](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/Upload.aspx.cs)) is done the control flow is the same as in the sample [PAdES signature with file already on server](https://docs.lacunasoftware.com/en-us/articles/rest-pki/dotnet/web-forms#pades), but with the URL parameter `userfile` filled. ### PAdES co-signature After the control flow of the sample [PAdES signature with file already on server](https://docs.lacunasoftware.com/en-us/articles/rest-pki/dotnet/web-forms#pades) 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](https://docs.lacunasoftware.com/en-us/articles/rest-pki/dotnet/web-forms#pades) sample which by default starts commented out. To enable it, uncomment the following line on [PadesSignatureController](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/PadesSignature.aspx.cs): ```cs 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](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/PadesVisualElements.cs), method `GetPdfMark(int)`. ### PAdES signature using server key Not yet available on this project. ### PAdES signature without client communication Not yet available on this project. ### 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](https://docs.lacunasoftware.com/en-us/articles/rest-pki/dotnet/web-forms#pades) 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](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/PrinterFriendlyVersion.aspx) and to its code behind [PrinterFriendlyVersion.aspx.cs](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/PrinterFriendlyVersion.aspx.cs) with the URL parameter `file` filled. The generated PDF contains links to the web form: [Check.aspx](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/Check.aspx) and to its code behind [Check.aspx.cs](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/Check.aspx.cs), which shows details of the signatures. ### CAdES signature with file already on server * Web Forms: * [CadesSignature.aspx](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/CadesSignature.aspx) * [CadesSignature.aspx.cs](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/CadesSignature.aspx.cs) * [CadesSignatureInfo.aspx](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/CadesSignatureInfo.aspx) * [CadesSignatureInfo.aspx.cs](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/CadesSignatureInfo.aspx.cs) * JavaScript: [signature-form.js](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/Scripts/signature-form.js) ### 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](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/Upload.aspx) and on its code-behind [Upload.aspx.cs](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/Upload.aspx.cs)) is done the control flow is the same as in the sample [CAdES signature with file already on server](https://docs.lacunasoftware.com/en-us/articles/rest-pki/dotnet/web-forms#cades), but with the URL parameter `userfile` filled. ### CAdES co-signature After the control flow of the sample [CAdES signature with file already on server](https://docs.lacunasoftware.com/en-us/articles/rest-pki/dotnet/web-forms#cades) 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. ### CAdES signature using server key Not yet available on this project. ### Open/validate an existing CAdES signature Not yet available on this project. ### XML signature of the entire document Not yet available on this project. ### XML signature of an element * Web Forms: * [XmlElementSignature.aspx](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/XmlElementSignature.aspx) * [XmlElementSignature.aspx.cs](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/XmlElementSignature.aspx.cs) * [XmlElementSignatureInfo.aspx](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/XmlElementSignatureInfo.aspx) * [XmlElementSignatureInfo.aspx.cs](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/XmlElementSignatureInfo.aspx.cs) * JavaScript: [signature-form.js](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/Scripts/signature-form.js) ### XAdES signature of an element Not yet available on this project. ### Open/validate signatures on an existing XML file Not yet available on this project. ### Batch of PAdES signatures * Web Form: [BatchSignature.aspx](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/BatchSignature.aspx) * [BatchSignature.aspx.cs](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/BatchSignature.aspx.cs) * JavaScript: [batch-signature-form.js](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/Scripts/batch-signature-form.js) ### Optimized batch of PAdES signatures * Web Form: [BatchSignatureOptimized.aspx](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/BatchSignatureOptimized.aspx) * [BatchSignatureOptimized.aspx.cs](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/BatchSignatureOptimized.aspx.cs) * JavaScript: [batch-signature-optimized-form.js](https://github.com/LacunaSoftware/RestPkiSamples/blob/master/CSharp/WebForms/WebForms/Scripts/batch-signature-optimized-form.js) ### Batch of CAdES signatures Not yet available on this project. ### Batch of XML signatures of elements on the same document Not yet available on this project.
