How eGuard Works
Four simple steps for the user, backed by hardware-token signing and an end-to-end encrypted relay.
Connect Your USB Token
Plug your USB DSC token into your Android phone using an OTG adapter. Your token and private key remain securely with you throughout the signing process.
Start Signing on Your PC
Open Adobe Acrobat, GST Portal, MCA, Income Tax, ICEGATE, Java signers, or any supported application and initiate the signing process.
Approve on Your Mobile
Receive a secure signing request on your registered mobile device. Review the request details and approve it only if everything looks correct.
Enter Your PIN & Sign
Enter your PIN securely on your mobile device. The token signs the document locally, and the completed signature is securely returned to your computer.
Four ways to sign, one platform
Pick a signing mode per certificate right in the eGuard host app — Remote Approval, Host PIN, Host + Mobile Code (TOTP), or API. Every mode keeps the token and PIN protected, with a complete audit trail.
