Browser extension for creating and verifying Russian electronic/digital signatures (ЭП) on web pages by bridging browser web apps with a locally installed native cryptographic application via Chrome native messaging

Enables electronic document signing and signature verification directly within web-based document management systems and personal cabinets (личные кабинеты), using local Russian cryptographic service providers (ViPNet CSP, КриптоПро CSP, Signal-COM CSP)

1. User installs the Chrome extension and the TrustPlugin native OS application separately. 2. When visiting a web page that supports TrustPlugin, the content script registers itself. 3. The web page's JavaScript sends signing/verification requests via postMessage. 4. Content script forwards requests to background script. 5. Background script relays to the native app via chrome.runtime.connectNative. 6. Native app performs cryptographic operations using local CSP and hardware tokens. 7. Results are returned back through the chain to the web page.

Target users: Russian government and business users who work with electronic document management systems (СЭД) / Users of Russian digital signature infrastructure (ГОСТ cryptographic algorithms) / Professionals signing documents in личные кабинеты (personal cabinets) of government and corporate portals

Native companion application (TrustPlugin for OS) source code is not available for review — only the browser extension was analyzed
The debugger/inspector pages (debugger/debugger.htm) are large binary HTML files that were not fully parsed
Cannot confirm whether the companion native application itself has paid/licensing requirements

Monetization

No paid features detected

No payment platforms, subscription logic, premium tiers, or upgrade-to-pay UI found in the extension source. The 'upgrade' keyword refers to prompting users to update the native companion application to a newer version, not a paid upgrade. The only 'payment' hit is an HTTP 402 status code comment in a generic crypto utility library. No Stripe, billing API, or feature-gating code exists.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: No login, account, or authentication required. The extension works as a local bridge between web pages and a native OS cryptographic application via chrome.runtime.connectNative. All 'auth' keyword hits refer to 'AuthRoot' certificate store management, not user authentication. No credentials, OAuth, or account creation found anywhere in the code.
