Class 2 vs Class 3 DSC
If you are still searching for a Class 2 certificate, the short answer is that they are no longer issued. Class 3 is what you need.
What happened to Class 2
India used to issue digital signature certificates in classes, with Class 2 used for routine filings and Class 3 for tenders and higher-assurance uses. Class 2 was discontinued and Class 3 became the standard for everything.
The practical effect is simple. If you are looking to buy a Class 2 certificate, you cannot — and you do not need to, because Class 3 covers everything Class 2 did. If a website is still offering you a Class 2 certificate today, that is a reason to be careful about who you are buying from.
If you are holding an old Class 2 certificate, it works until it expires and then you replace it with Class 3. There is nothing to do in the meantime.
The distinction that still matters
| What it is | Who needs it | |
|---|---|---|
| Signing certificate | Proves a document came from you and has not been altered | Everyone. This is the basic certificate |
| Encryption certificate | Locks a financial bid so it cannot be opened before the scheduled time | Anyone bidding on e-procurement portals |
| Combined | Both, usually on one token | Contractors and suppliers who bid |
This is now the question that actually matters when buying, and it is the one people get wrong. Class is no longer a choice; signing versus signing-plus-encryption is. Buying only the signing certificate and discovering the gap on the day a tender closes is the expensive version of this mistake.

Individual or organisation
The other real choice. A certificate is issued either in a person's own name or in an organisation's name with a named authorised signatory. Portals check this against how you are registered, and a mismatch means buying again.
