A Digital Signature Certificate (DSC) is a secure digital key issued by a Certifying Authority. It is used to digitally sign electronic documents and authenticate identity for government portals like Kalanjiyam, Income Tax, GST and MCA.
Used for personal filings such as Income Tax and GST returns.
Used for company directors and authorized signatories.
Digital signatures are stored securely in a USB cryptographic token (dongle). This prevents copying or misuse of the signature.
