What is a Digital Signature Certificate (DSC)?

A DSC is just like a physical signature in an online electronic format. A Certifying Authority (CA) issues it as a secure digital tool to confirm the identity of the person to whom the certificate belongs. It ensures that your signatures represent the real person and keep the data unchanged.

Why is DSC Required for Business Registration?

If you are starting a business online, the Ministry of Corporate Affairs (MCA) asks business owners, directors or partners in India and similar organisations in other countries to electronically sign several documents. With a DSC, companies are able to:

Those signing the document are checked for their identity.
These documents can no longer be changed.
Information remains governed under legal and cybersecurity laws.
