Why is it required? Unlike standard web browsing, submitting government tenders requires a high level of security and authentication.

1. Digital Signatures: The client integrates with your Digital Signature Certificate (DSC) token to sign documents.

1. Download ZIP from portal (HTTPS) and compare SHA256 with published value.

Failure resolution example:

• If signature verification fails, bidder exports certificate chain, checks expiry, and uses the vendor support channel to reissue or update certificate mapping.
