DSC stands for Digital Signature Certificate, which is a digital equivalent of a physical or paper certificate that is used to verify the identity of an individual or an organization in electronic transactions. It is a secure way of signing electronic documents, just as we sign physical documents with a pen.

A Digital Signature Certificate is issued by a Certifying Authority (CA) and is used to authenticate and verify the identity of the person or organization signing the electronic document. It is a tamper-proof, secure, and legally recognized way of signing electronic documents.

A Digital Signature Certificate can be used for various purposes such as e-filing of income tax returns, e-tendering, e-procurement, and other online transactions. It helps to ensure the authenticity and integrity of the electronic document and prevents unauthorized access, tampering, or modification of the document.

To obtain a Digital Signature Certificate, an individual or organization needs to apply to a Certifying Authority (CA) with the required documents and undergo a verification process. Once the verification process is completed, the CA issues the Digital Signature Certificate in the form of a USB token or a smart card.

In summary, a Digital Signature Certificate (DSC) is a digital equivalent of a physical signature used to sign electronic documents. It is a secure and legally recognized way of signing electronic documents, and it is issued by a Certifying Authority (CA) after verifying the identity of the person or organization. A DSC helps to ensure the authenticity and integrity of the electronic document and prevents unauthorized access, tampering, or modification of the document.
