string
The information provided by the signer to enable a recipient to contact the signer to verify the signature (for example, a phone number).
location:
string
The CPU host name or physical location of the signing.
reason:

The reason for the signing, such as "I agree...".
signatureField:
string
The signature field name used to store a digital signature.
signerName:
string
The name of the person or authority signing the document. NOTE: This value is used only if it is not possible to extract the name from the signature, for example from the certificate of the signer.
Send a request to the server to save the document with signature.
viewer.save("test.pdf", { sign: { signatureField: "field1", signerName: "John Doe" } } );
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
};
