A Digital Signature Certificate (DSC) is a secure and legally binding electronic signature that substitutes the old handwritten (wet) signature to the digital documents and online transactions. It is employed to confirm the identity of a person or set up in transacting business or filing documents online.
A DSC makes sure the personal data of a signer, including his or her name, email address and a unique identifier, is safely linked to his or her digital signature. This makes governments, businesses and individuals ensure that they are dealing with a signed document and that a document has not been tampered with.
