A Digital Signature Certificate (DSC) is like your online signature—secure, legally valid, and encrypted. It is used widely across India for business and government filings, including company incorporation, GST, income tax, e-tendering, and more. Some certificates allow only signing documents, while others support both signing and encrypting data for extra security.
