Function AddDocTimestamp(name As string) As Signature

 

    

Params

Add an RFC 3161 compliant document timestamp field to the form.

To sign the timestamp you need to specify either a TimestampServiceUrl or a CustomSigner and then call Timestamp.

 

    

Example		  

See the Annotations example project for a full example.

However the following is a code snippet showing how this might be used.

 

using var doc = new Doc(); // ... set up the doc perhaps by reading a PDF if (doc.PageCount == 0)   doc.Page = doc.AddPage(); var sig = doc.Form.AddDocTimestamp("Timestamp"); var uri = new Uri("http://timestamp.digicert.com"); var oid = new Oid(CryptoConfig.MapNameToOID("SHA256")); sig.TimestampServiceUrl = uri; sig.Timestamp(oid, 0);
