Type alias SignatureInfo

SignatureInfo: { contactInfo: string; location: string; reason: string; signatureField: string; signerName: string }

Information about the document signature that will be used to sign the document.

viewer.save("test.pdf", { sign: { signatureField: "field1", signerName: "John Doe" } } );

Example

Example of server side signing implementation

// Example: electronically sign PDFs with a .PFX certificate:

public void Configuration(IAppBuilder app) {
    GcPdfViewerController.Settings.Sign += _OnSign;
    // ... 
}

private void _OnSign(object sender, SignEventArgs e)
{
    var signatureProperties = e.SignatureProperties;
    X509Certificate2 certificate = new X509Certificate2(System.IO.File.ReadAllBytes("certificate.pfx"), "password", 
      X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.PersistKeySet | X509KeyStorageFlags.Exportable);
    signatureProperties.SignatureBuilder = new Pkcs7SignatureBuilder()
    {
       CertificateChain = new X509Certificate2[] { certificate },
       HashAlgorithm = Security.OID.HashAlgorithms.SHA512,
       Format = Pkcs7SignatureBuilder.SignatureFormat.adbe_pkcs7_detached
    };
}
