Abstract
A generator uses a robust programming framework to create an electronic signature in association with a data item, wherein the electronic signature includes time stamps and/or countersignatures. The generator can create a signature object that computes a signature value of the electronic signature based on the data item. The generator also creates a signature timestamp object to obtain a timestamp of the signature value, wherein the timestamp is associated with the electronic signature. The generator can also invoke a countersignature service on the signature object to obtain a countersignature based on the signature value of the signature object, wherein the countersignature is associated with the electronic signature.
