FAQ :
In India, only government-approved Certifying Authorities (CAs), regulated by the Controller of Certifying Authorities (CCA), are authorised to issue Digital Signature Certificates (DSCs).
DSCs are available in different classes, including Class 1 for basic email use, Class 2 for business and official filings, and Class 3 for high-security needs like e-tendering and legal purposes. They can also be for signing only, encryption only, or a combination of both, with validity periods of 1 to 3 years.
A Digital Signature Certificate (DSC) is generally valid for a period of 1 to 3 years, and it's important to renew it before it expires.
If your DSC expires, you need to apply for a renewal with your Certifying Authority. If it is lost, you should revoke the old certificate and apply for a new one with fresh documentation.
For higher-grade DSCs, such as Class 3, a secure USB token is often necessary to store the certificate and enable its use across multiple computers.
