Basic Information Of Digital Signature certificate

What is Digital Signature Certificate?

A Digital Signature Certificate or DSC plays the role of the normal handwritten signature, but it serves as a certificate like a driving licenses or passport.

The DSCs serve as a proof of identity for a person or an organization for specific purpose online.

In simple language, Digital Signature Certificates serve as an electronic proof of your identity in the cases of accessing online information or online transactions.

How does it work?

  • Basically, Digital Signature Certificate (DSC) associates the identity of an individual/device with public and private keys.
  • It contains information about a user’s identity (such as their name, pin code, country, email address, the date the certificate was issued, name of the CA).
  • These keys won’t work in the absence of the user.
  • They are used by browsers and servers to encrypt/ decrypt information regarding the identity of the certificate user.
  • The private key is stored on the hard disk of the user’s computer or on an external device such as a USB token.
  • The user retains control of the private key and it can only be used with the issued password.
  • The public key is distributed with the encrypted information. So, if one of these keys in not available or do not match, the authentication process fails. This means that the encrypted data cannot be decrypted and therefore, is inaccessible to unauthorized parties.

A DSC is issued by the licensed Certifying Authority (CA). It means a person who is granted a licence to issue a Digital Signature Certificate under Section 24 of the Indian IT, Act 2000. You can check out the list of licensed CAs here
