A Digital Signature Certificate (DSC) Certificate authenticates your identity electronically. It provides you with a high level of security for your online transactions by ensuring absolute privacy of the information exchanged using a Digital Signature Certificate (DSC). You can use certificates to sign/encrypt information such that only the intended recipient can read it. You can digitally sign information to assure the recipient that it has not been changed in transit, and also verify your identity as the sender of the message.
