To Digitally sign a PDF file with multiple signaturesGemBox.Pdf is also helpful when creating a document that needs more than one signature. For example, a contract in PDF that requires signatures of both the company and the author.To add two or more signatures to a PDF document in C#, you can refer to the following code:After loading an existing PDF file, add a first signature field to the first page of the PDF document, and the first digital ID from a PFX file.C#var signatureField1 = document.Form.Fields.AddSignature(document.Pages[0], 100, 500, 200, 50); var digitalId1 = new PdfDigitalId("GemBoxRSA1024.pfx", "GemBoxPassword"); Create a PDF signer that will create the first signature. Also, embed the certificate of intermediate Certificate Authority in the signature.C#var signer1 = new PdfSigner(digitalId1); signer1.ValidationInfo = new PdfSignatureValidationInfo( new PdfCertificate[] { new PdfCertificate("GemBoxRSA.crt") }, null, null); Initiate the first signing of the PDF file with the specified signer.C#signatureField1.Sign(signer1); Finish the first signing by saving it to a new PDF file.C#document.Save("Multiple Digital Signature.pdf"); Add a second signature field to the first page of the PDF document.C#var signatureField2 = document.Form.Fields.AddSignature(document.Pages[0], 300, 500, 250, 50); Get a second digital ID and create a PDF signer that will generate the second signature.C#var digitalId2 = new PdfDigitalId("GemBoxECDsa521.pfx", "GemBoxPassword"); var signer2 = new PdfSigner(digitalId2); Once more, you need to embed the certificate of intermediate Certificate Authority in the signature.C#signer2.ValidationInfo = new PdfSignatureValidationInfo( new PdfCertificate[] { new PdfCertificate("GemBoxECDsa.crt") }, null, null); Initiate the second signing of the PDF file with the specified signer.C#signatureField2.Sign(signer2);Finish the second signing of the same PDF file (Multiple Digital Signature.pdf).C#The following screenshot shows a PDF file containing two revisions (two digital signatures) created by the code above.Screenshot of a Pdf document with two digital signatures.How to digitally sign a PDF file with a PDF Advanced Electronic Signature (PAdES)PDF Advanced Electronic Signature (PAdES) is an electronic signature
