A Class 3 Digital Signature Certificate (DSC) is the highest level of digital signature used for secure online transactions and document authentication. It is commonly required for e-tendering, e-procurement, e-bidding, trademark and patent filing, ICEGATE customs filing, and other government or corporate portals. The certificate is issued after proper identity verification and stored in a secure USB token, ensuring data integrity and protection from tampering.
Class 3 DSC is available for individuals as well as organizations and may be issued as a signing certificate or a signing-and-encryption combo certificate. The signing certificate is used to digitally sign documents, while the encryption certificate protects sensitive data during transmission.
Because of its high level of security and wide acceptance, Class 3 DSC is widely used by contractors, companies, Chartered Accountants, professionals, and government vendors who need to submit high-value tenders or comply with statutory online filings.
