Introduction

Use DSC digital signatures via SecureSign Mobile App and Desktop Software — no Java, browser extensions, or token drivers.

Important — How SecureSign Is Offered

Toolsbots SecureSign is delivered as two ready-to-use products for integrators and end users:

  • SecureSign Mobile App — Android & iOS (mobile browser deep link, app handoff)
  • SecureSign Desktop Software — Windows, Linux & macOS (desktop browser deep link)

We do not provide public Android, iOS, Linux, or macOS SDK packages. Embedded desktop SDKs are available only through enterprise licensing to protect our source code and intellectual property.

Overview

SecureSign is a DSC (Digital Signature Certificate) platform by Toolsbots. Integrators connect government portals and business websites to our Mobile App and Desktop Software — users sign with their physical DSC token without installing token drivers or browser plugins.

On mobile, your website opens the SecureSign App via deep link. On desktop browsers (Windows, Linux, macOS), your website calls the locally installed SecureSign Desktop Software. The signed result returns to your portal automatically.
