What is Digital Signature Certificates?

Digital Signature Certificates (DSC) is the electronic format of physical or paper certificate like a driving License, passport etc. Certificates serve as proof of identity of an individual for a certain purpose; for example, a Passport identifies someone as a citizen of that country; who can legally travel to any country. Likewise, a Digital Signature Certificate can be presented electronically to prove your identity, to access information or services on the Internet or to sign certain documents digitally.

How it Works?

A Digital Signature Certificate explicitly associates the identity of an individual/device with a pair of electronic keys – public and private keys – and this association is endorsed by the CA. The certificate contains information about a user’s identity (for example, their name, pincode, country, email address, the date the certificate was issued and the name of the Certifying Authority that issued it). These keys complement each other in that one does not function in the absence of the other. They are used by browsers and servers to encrypt and decrypt information regarding the identity of the certificate user during information exchange processes. The private key is stored on the user’s computer hard disk or on an external device such as a token. The user retains control of the private key; it can only be used with the issued password. The public key is disseminated with the encrypted information. The authentication process fails if either one of these keys in not available or do not match. This means that the encrypted data cannot be decrypted and therefore, is inaccessible to unauthorized parties.

What is the difference between a Digital Signature and a Digital Signature Certificate?

A digital signature is an electronic method of signing an electronic document whereas a Digital Signature Certificate is a computer based record that Identifies the Certifying Authority issuing it. Has the name and other details that can identify the subscriber. Contains the subscriber’s public key. Is digitally signed by the Certifying Authority issuing it. Is valid for specified period of time.
