A Digital Signature also called DSC (Digital Signature Certificate). It is a digitally secure code that is issued by the certifying authorizations for the use of certifying and validating the identification of the person holding this certificate. Digital Signatures have the public key encryptions to generate the signatures.
A digital signature certificate (DSC) includes data about the individual’s/organization’s name, pan card no., address details, pin code, email address, date of issuance of the certificate and certifying authority.

How does a Digital Signature Certificate work?
A Digital Signature Certificate explicitly associates the identity of a device with a pair of electronic keys: Private key and Public key –
This association is endorsed by the Certifying Authority. The certificate
contains information about a user’s identity when the certificate was issued and the name of the Certifying Authority.
These keys complement each other in that one does not work in the loss of the other.
They are used by browsers and servers to encrypt and decrypt data regarding the identity of the Certificate User during the information transfer process. The Private Key is stored on the user’s Token. The user retains control of the Private Key which can only be used with the password. The Public Key is broadcasted with the encrypted information. The authentication process fails if either one of these keys does not match. This means that the encrypted data cannot be decrypted and therefore is unavailable to unauthorized parties. Hence to summarize, a DSC contains a pair of Keys one for Signing and another for Encryption. So when a Digital Signature works, it looks for the Signing Certificate and the Encryption Certificate of the User.
