This certificate or digital ID must be installed through the indications provided by the certification authority you have chosen. The next step in sending an encrypted message is to send messages that are digitally signed. But this action must also be performed by the recipient, who must also send messages that are digitally signed.

To do this you just have to open a message and select “Options” then “More options” and in the box with 2 properties you must choose the option “Security settings” . Then in Security Properties, you must check the box “Add digital signature to this message” when finished click on the “OK” option.
