Digital Signature Certificates (DSC) are the digital
equivalent (that is electronic format) of physical or paper certificates.
Few Examples of physical certificates are drivers' licenses, passports or
membership cards. Certificates serve as proof of identity of an individual
for a certain purpose; for example, a driver's license identifies someone
who can legally drive in a particular country. 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.
