digital signature using qoppa pdf studio pro

Validation of a timestamped digital signatures is automatic and does not require any additional call in the libraries or components. setTimestampServer( TimestampServer server) To apply a digital signature with a timestamp, it is as simple as setting up the parameters for the timestamp server in the new TimeStampServer class and then pass on this class to the SigningInformation class used for signing:

jPDFViewer (Java PDF Visual Component): Verify visually PDF digital signatures with time-stamp.

jPDFNotes, jPDFEditor (Java PDF Visual Components): Apply and verify visually PDF digital signatures with time-stamp.

jPDFSecure, jPDFProcess (Java PDF Libraries): Apply and verify PDF digital signatures with time-stamp.

Starting version 2013R1, it is possible to apply and verify digital signatures with a time-stamp authenticated by a trusted, independent authority using the following Qoppa’s java PDF library products: The Bouncy Castle libraries, which Qoppa’s products rely on for encryption, do support this protocol and so we added support this in our libraries as well in version 2013R1.

Support for Timestamped Digital Signature in Qoppa’s PDF library products Timestamps are essentially encapsulated in another certificate signed by the authority which contains both the customer’s and the time-stamp server’s signatures. Many security standards (in Europe for instance) require this added level of security to encrypt administrative and legal documents. It have optical character recognition capabilities. Pros: It is the best PDF editor and converter available with a low-cost perpetual license. It is quick, simple to use, and has a nice user interface. Time-stamp servers, also called Time Stamp Authorities (TSA), can provide a legal timestamp and there is a protocol to access the servers and get the timestamp back. Overall: PDF Studio has a user-friendly design and is the finest alternative to Adobe Acrobat. But this may not be valid in a lot of legal environments. When creating a digital signature, it is possible to simply use the computer’s date and time.
