Our verdict

When a web portal asks you to 'install emBridge' before DSC registration or signing, this is the program it means. It runs quietly as a Windows service (or a daemon on Mac and Linux) and gives the website a secure local channel to your token, so no Java is needed. CDSL's help page, for example, sends users here for DSC mapping. It does not replace your token driver: install the ePass, ProxKey, mToken or other driver first, then emBridge.

Install guide · इंस्टॉल गाइड

Windows: Windows 7 and above

1Install your USB token's driver first (ePass 2003, ProxKey, mToken etc.) and check the token is detected.
2Open embridge.emudhra.com, go to Downloads and click the installer for your system (Windows, Mac, Ubuntu or Red Hat).
3Run the installer and click Install; it stops and removes any older emBridge before installing the new one.
4Plug in the token, reload the portal page and choose your certificate when the portal asks for it.
