Frequently Asked Questions
Can I sign a PDF with my DSC USB token in the browser?▾
Yes. EverydayPDF connects to your Class 3 DSC USB token (ePass, ProxKey, Watchdata) through a small local bridge and applies a PAdES-compliant embedded signature. The PDF is prepared and signed on your own computer — it is never uploaded.
Are signatures made with EverydayPDF valid for MCA, GST, and Income Tax filings?▾
Yes. The tool produces standard PAdES embedded signatures from your government-issued Class 3 certificate — the same signature format accepted by MCA, GST, Income Tax, and tender portals.
Which DSC tokens are supported?▾
Common Indian Class 3 tokens are supported, including ePass 2003, ProxKey, and Watchdata. A one-time two-minute setup installs the local bridge, similar to emsigner.
