Digital Signature Certificate (DSC): DSC is a specific type of digital certificate that is issued by licensed Certifying Authorities (CAs) in India in compliance with the Information Technology Act, 2000 and the corresponding rules and regulations. It serves as a legally recognized form of digital signature within the country. DSCs are primarily used to secure electronic transactions, file electronic documents, and ensure the authenticity and integrity of digital information. It is governed by the Controller of Certifying Authorities (CCA), which is the regulatory body responsible for licensing and overseeing CAs in India.
According to the corporate affairs ministry’s FAQs on DSC, Class 2 DSCs are needed to verify a person against a trusted, pre-verified database while Class 3 DSCs seek a person to be present in front of a Registration Authority (RA) to prove his/ her identity. Class 1 DSCs only verify the name and email address of the individual. However, Class 2 DSCs were discontinued in 2021, according to multiple reports. The certifying authorities are authorized to issue a DSC with a validity of one or two years.
DSCs are widely implemented in various applications, including filing income tax returns electronically, Goods and Services Tax (GST) returns and other related transactions, digitally signing of documents during the incorporation of companies, submitting electronic bids and participating in online tendering processes, online banking transactions and other financial activities, etc.
