A Digital Signature Certificate (DSC) is used to electronically sign documents submitted online by an authorized person. It ensures the security and authenticity of electronic documents. A DSC is mandatory for filing documents on the Ministry of Corporate Affairs (MCA) portal.
Online processes such as company or LLP incorporation, statutory filings, and income tax e-filing are validated using a DSC.
The Controller of Certifying Authorities (CCA) authorizes Certifying Authorities (CAs) to issue Digital Signature Certificates. These authorities are licensed to issue Class 3 DSCs, which offer a high level of security.
