What is a Digital Signature Certificate (DSC)

A Digital Signature Certificate is an e-document that validates the identity of an individual or an organization. A digital signature certificate application form can be submitted online with all the requisite details. Using a digital signature, the certificate binds the identity of an individual or an organization (using the name, email ID, pin code, location, issuing authority date of issuance) with a public key. Every time a DSC is in usage, the public key verifies identity.

How Digital Signature works_

DSCs are issued by a licensed Certifying Authority (CA), who is legally empowered to do so. When one applies for a DSC, it is the CA that assesses and approves each application and issues the DSC.

Licensed Certifying Authorities (CA)

E-MUDHRA (n) Code Solutions CA SafeScrypt CA Services, Sify Communications Ltd.
IDRBT Certifying Authority National Informatics Center (NIC) CDAC
NSDL Capricorn Verasys

Each of these CAs issue DSC tokens and their respective PINs to users, along with their certificates. To place a digital signature on a document, a user has to insert a DSC token into his/her computer at the time of signing documents and then enter its corresponding PIN. If the PIN does not match the DSC token, the user will not be able to sign the document.
