A Digital Signature Certificate (DSC) helps to validate an electronic document, be it pdf or otherwise. A digital signature certificate is one of the best ways of making sure that one’s documents are secure or in the right hands.
This is because the sender of the document is notified of any change made in the document. The Digital signature certificate also helps us to identify the sender or receiver of the document.
Digital signatures are a standard element of most cryptographic protocol suites, and are commonly used for software distribution, financial transactions, contract management software, and in other cases where it is important to detect forgery or tampering.
