Digital Signature Certificates (DSC) are the digital equivalent (that is electronic format) of physical or paper certificates. … Likewise, a digital certificate can be presented electronically to prove one’s identity, to access information or services on the Internet or to sign certain documents digitally.
A digital signature is a way to identify yourself online. Just like passports, driving licenses, and PAN cards allow you to prove your identity offline, digital signatures let you prove your identity online. To do this, you need a digital signature certificate and that lets you sign documents digitally.
