இந்தக் கருவி பற்றி About this tool

A short checklist for the most common DSC problems: token not detected, PIN locked, signer utility not connecting, certificate expired or signature invalid on TRACES, GST and e-filing uploads. It also explains what this site can and cannot do: it verifies signatures and warns you before you break one, but signing with a USB token needs your token driver and CA utility. DSC Token Help is part of PDF Tools India's PDF toolkit. Fix DSC USB token, emSigner, Java and “signature invalid” problems. Runs entirely in your browser — your file is never uploaded to a server. Available in Tamil and English, on both mobile and desktop, with no account required to try it.

🔒 Runs entirely in your browser — your file is never uploaded to a server.

எப்படிப் பயன்படுத்துவது? How it works

  1. Check that the token driver from your CA is installed and the token shows in its manager.
  2. Make sure the signer utility (for example emSigner) is running and not blocked by antivirus.
  3. Keep the system date and time correct and use an up-to-date Chrome or Edge.
  4. Never edit or compress a PDF after signing; verify it with the DSC Verifier.

அடிக்கடி கேட்கப்படும் கேள்விகள் FAQ

Do I still need Java for DSC?

Most government portals no longer use the old Java applet; they use a small utility on your computer. Follow the current instructions on the portal you are using.

Can you remove the need for the signer utility?

No. A website cannot read a USB token without software on your computer; that is a browser security rule.

Can I compress a signed PDF?

Compressing rewrites the file and breaks the signature. Compress before signing instead.

Is DSC Token Help free to use?

Yes. DSC Token Help is free on PDF Tools India — no signup, no watermark and no daily limit.

Is my data safe when I use DSC Token Help?

Yes. DSC Token Help runs inside your own browser, so your files and text never leave your device.

Does DSC Token Help work on mobile?

Yes. DSC Token Help works on Android phones, iPhones, tablets and desktop browsers. The interface is available in Tamil and English.
