Setting up your DSC from scratch

1

Install your token's driver first

Every USB token brand (Proxkey, InnaIT, HypSecu, ePass, Bit4id) needs its own manufacturer driver, download it from the official brand website, never a third-party source.

2

Install the token's management software

This lets your system recognize and manage the certificate stored on the token, usually bundled with or alongside the driver.

3

Install portal-specific signing middleware, if needed

GST needs emSigner, MCA and Income Tax need emBridge, ICEGATE needs its own PKI component, install whichever your target portal requires.

4

Restart your browser completely

A full restart, not just a page refresh, after any driver or middleware installation.

5

Test with a low-stakes signature first

Before relying on it for an actual filing, sign a test document to confirm everything works end-to-end.

Common installation mistakes

Installing drivers from unofficial or third-party sites, not restarting the browser after installation, and having multiple token utilities from different brands running simultaneously are the most common causes of installation-related signing failures.
