A Digital Signature Certificate (DSC) is a secure digital key issued by certifying authorities to validate and authenticate the identity of the certificate holder. It is widely used in India for eTendering, eFiling, ICEGATE, DGFT, GST, MCA, Income Tax filing, and other government and corporate services.

Step 1: Insert Your USB DSC Token

• Plug your USB token into a USB port.
• Wait until your system detects the new device.

Step 2: Install the Token Driver

1. Visit the official website of your DSC provider (e.g., eMudhra, Capricorn, VSign, Sify).
2. Download the correct driver for your token (e.g., ePass 2003, ProxKey, Watchdata).
3. Run the installer as Administrator.

2. Download the offline installer.
3. Run the setup and install Java on your system.
4. Open Control Panel → Java → Security:

  • Add required websites (e.g., https://www.icegate.gov.in, https://eprocure.gov.in) under Exception Site List

Step 4: Check USB Token Detection
