There are three classes of digital signature certificate and their functions are as follows:
- Class 1: The name and email address of individuals can be verified. This is not to be used by companies.
- Class 2: A Class 2 digital signature certificate verifies the identity of a person against a pre-verified, trusted database. This is the one needed for companies or trusts to file their tax returns.
- Class 3: This is the highest and most secure digital signature certificate available in India. To get this a person needs to present himself or herself in front of a registration authority to prove his or her identity. This category is needed for those who want to participate in online auctions or tenders.
Certifying authorities (CA) in India don't usually sell class 1 certificates. The reason class 2 and 3 certificates are most commonly used on government portals and that class 1 doesn't authenticate anything except your name and email address.
