To begin, you must first ensure that the IT department has approved the digital signature, whether it is registered or not. For this, you need to submit the DSC activation letter in three copies, which can be downloaded from the portal.
You can check the status of the digital signature to confirm that it is active. Following this, you will need to download the DSC service utility and configure it through the trusted root path.
Once these steps are completed, you will be able to use the DSC for signing documents.
