What is a Class 3 Digital Signature Certificate?
A Class 3 Digital Signature Certificate is the highest-assurance DSC issued in India — the digital equivalent of a handwritten signature, backed by encryption that makes it legally valid for signing documents and authenticating your identity online. It's the certificate required for e-tendering, GST and MCA filings, trademark applications, and other portals where identity verification matters most.
