Control is YoursSign without Sharing Your Token & PIN

eGuard Remote Sign represents a PIN-proof digital signature platform designed for India's DSC (Digital Signature Certificate) ecosystem. It enables USB cryptographic token signing of documents from PC applications while keeping the token and PIN secure on the device itself — signing occurs exclusively on the token chip.

Complete Signing Logs. No Token Sharing. No PIN Exposure.

Remote Approval

The certificate stays on the owner's phone, and every signature is approved there.

Future Proof Digital Signing

Everything You Need for Secure Remote Signing

eGuard enables secure remote digital signatures without moving your USB token. Continue using Adobe Acrobat, GST, MCA, Income Tax, ICEGATE, Java signers, and other supported applications, while keeping your credentials protected at every step.

Detailed Activity Logs

Maintain a complete history of every signing request, including timestamps, device details, application information, and approval status, for enhanced visibility and accountability.

PIN-Proof Security

Your PIN is entered only on your mobile device and never travels across the network or reaches the host computer, helping protect your credentials from unauthorized access.

Zero Trust Host

The host computer works only with a secure digital fingerprint of the document, and your PIN is never placed on the network.

Complete User Control

Every signing request is delivered directly to your registered mobile device, where you can review, approve, or reject it before any signature is created.

Hardware Token Signing

The signature is created inside the USB token's secure chip. Only the completed digital signature is returned to the requesting application.

Compatible with Existing Infrastructure

Continue using your existing Digital Signature Certificates, USB tokens, and supported signing applications without changing your current workflow or infrastructure.

Security model

Architecturally Designed to Protect Your Digital Identity

Unlike traditional digital signing, eGuard keeps your USB Token and PIN under your control and records every signature in a detailed audit log. Your PIN is never placed on the network, reducing the risk of unauthorized access by design.

3-layer encryption

TLS transport, XChaCha20-Poly1305 AEAD payloads and Ed25519 message signatures provide defence in depth on every hop.

3-factor authentication

Physical token (have), PIN (know) and bound mobile device (possess) — all three are required to produce a signature.

Perfect forward secrecy

A fresh ephemeral X25519 key per message. Capturing one session reveals nothing about any other.

Key inside the chip

Signing is performed inside the USB token's hardware chip, and only the finished signature ever leaves it.

Workflow

Remote Signing in Four Simple Steps

Complete legally valid digital signatures without exposing your PIN or moving your USB token.

1

Connect your token

Plug your USB DSC token into your Android phone using an OTG adapter. Your token stays securely with you throughout the signing process.

2

Start signing from your PC

Use Adobe Acrobat, the GST portal, MCA, Income Tax, a Java signer or any supported application. The PC sends only a secure fingerprint of the document.

3

Secure approval on your phone

Your phone receives an encrypted signing request. Review the request and verify its details before you approve it.

4

Enter PIN & complete signing

Enter your PIN only on your mobile device. The token signs the document locally and the finished signature is returned to your PC.

Cross-platform supported

Download. Connect. Sign securely.

One account, every device — available on Android and iOS, plus Windows, macOS and Linux.

MOBILE APP

Android & iOS

Keep your USB DSC token connected to your phone. Receive signing requests, verify every transaction and approve signatures securely from anywhere.
