It sports a simple and clean interface that offers quick access to all its many options. The application supports batch processing, which means you are able to sign multiple documents simultaneously.
Before starting the signing process you have to specify an input and output destination. You can drag and drop the items directly into the main window, or use the browse button for adding files to the list.
It is possible to add a text to your signed documents by typing in the message in the dedicated dialog, and by choosing the algorithm from a preset list. The signed files can be saved as p7s or p7m format.
Moreover, you can ensure that the signature is genuine and the document was not changed after you have signed it, by adding timestamps. You have to specify the time stamp server, user name and password, and to pick an algorithm.
In order to carry out the signing process, you have to provide the digital certificate used for signing, and opt for the Windows certificates or PFX digital certificate file. When the last mode is enabled, you are required to add a PFX file to the list and a password.
