Knowledge Base around class 3 DSC

A Digital Signature Certificate (DSC) is a secure digital credential that verifies the identity of an individual or organization when signing electronic documents or accessing online services. It uses Public Key Infrastructure (PKI) and cryptographic technology to create legally recognized digital signatures, protect document integrity, and authenticate the signer. In India, Digital Signature Certificates are issued by licensed Certifying Authorities (CAs) operating under the regulatory framework of the Controller of Certifying Authorities (CCA).

A Digital Signature Certificate (DSC) works by using Public Key Infrastructure (PKI) and cryptographic technology. When a document is digitally signed, a unique hash of the document is created and encrypted using the signer's private key. Anyone receiving the document can verify the signature using the corresponding public key stored in the Digital Signature Certificate, ensuring the document is authentic, unchanged, and signed by the rightful owner.
