Frequently asked questions
What is a Digital Signature Certificate?
A DSC is a digital credential used to authenticate a signer and digitally sign electronic documents or transactions.
Who issues DSCs in India?
DSCs for end-users are issued by Certifying Authorities licensed by the Controller of Certifying Authorities (CCA).
What is the difference between a signature certificate and an encryption certificate?
A signature certificate is used for digital signing/authentication, while an encryption certificate is used for encryption-related purposes. The CCA states that an individual’s signature and encryption certificates should be separate.
Is Class 3 DSC still relevant?
Yes, Class 3 remains part of the current CCA certificate-class framework. Its verification requirements include prescribed eKYC/video or other permitted verification routes, and the private key is required to be stored in a hardware cryptographic device meeting the applicable security requirements.
Can one DSC be used for multiple portals?
It can be used across applications where the same certificate type and required information are accepted. However, the exact requirements depend on the application or portal. The CCA notes that a higher-assurance Class 3 certificate can be used where a lower-assurance certificate is required, subject to the application’s requirements.
How long is a DSC valid?
Validity depends on the certificate/product selected. Common commercial offerings include 1-, 2- and 3-year periods.
Can I get a DSC online?
Yes, licensed Certifying Authorities provide online application/verification routes where applicable. The exact verification method depends on the certificate and identity-verification route.
