Types and Classes of Digital Signature Certificates:

  1. Class 1 DSC: Ideal for individuals or private subscribers, Class 1 DSC validates the user's identity and email address, making it suitable for securing email communications.

  2. Class 2 DSC: Designed for individuals and organizations alike, Class 2 DSC offers a higher level of security. It is utilized for various purposes, including income tax filings, GST submissions, and filings with the Ministry of Corporate Affairs (MCA).

  3. Class 3 DSC: At the zenith of security, Class 3 DSC is indispensable for online participation in e-tendering, e-auctions, and legal filings like patents and trademarks. It involves stringent personal presence verification of the applicant.

Cost for New Digital Signature Certificate in India:

The cost of acquiring a Digital Signature Certificate in India varies based on the type and class selected. Generally, it ranges from INR 1000 to INR 3000. Class 1 certificates are the most economical, followed by Class 2, while Class 3 commands a higher price due to its advanced authentication protocols.
