Sign Like a Pro.
Without the USB.
Cygner is mobile-first cryptographic signing for the everyday professional documents your DSC was never designed for: client letters, opinions, advisory notes, and the dozens of attestations you sign every week. Built for CAs, lawyers, doctors, and every professional who signs documents daily.
Cygner is a non-statutory professional attestation tool. Statutory filings (MCA21, GST, income tax e-filing, e-tenders, and similar) still require a CCA-licensed Digital Signature Certificate (DSC).
Professional Signing, Reimagined
Built for the everyday professional signing your DSC was never designed for.
No USB Token
Your phone becomes your signing device. No more carrying a USB dongle or worrying about losing it.
Professional Identity
Your ICAI, BCI, or NMC registration is embedded in every signature. Clients verify your credentials instantly.
C2PA Provenance
Industry-standard Content Credentials are embedded in every signed document. Tamper-proof and globally verifiable.
Always Available
Sign from any device, anytime, anywhere. No browser plugins, no driver installs, no Java dependencies.

Cygner does not replace a CCA-licensed DSC for statutory filings (MCA21, GST, income tax e-filing, e-tenders, EPFO, DGFT, and similar). It is a non-statutory professional attestation tool for the everyday signed documents that sit outside those statutory regimes.
