Bridge/connector between SKB Kontur web services and a native cryptographic messaging host (kontur.plugin), enabling browser-based digital signature and cryptographic operations

Russian businesses using SKB Kontur services (tax reporting, electronic document flow, digital signatures) need to perform cryptographic operations from within their browser, but browsers cannot directly access local cryptographic hardware/software. This extension bridges that gap via Chrome's native messaging API.

User visits a SKB Kontur web service (e.g., extern.kontur.ru) → web page detects extension via meta attribute → sends cryptographic request via postMessage ('kontur-toolbox-request') → content script forwards to background script → background script connects to native messaging host 'kontur.plugin' → native app performs crypto operation (signing, encryption) → result flows back through the same chain to the web page

Target users: Russian businesses and accountants using SKB Kontur services / Tax professionals using Kontur.Extern for tax reporting / Organizations using Diadoc for electronic document exchange / Users of Kontur digital signature services (Контур-Сертификат, Контур.Подпись)

Cannot inspect the native messaging host 'kontur.plugin' source (separate desktop application), which may contain its own licensing/payment logic
Cannot determine the full scope of Kontur web services that use this extension or their specific authentication requirements
The extension is minimal (2 source files, ~330 lines total) — clear and well-understood

Monetization

No paid features detected

The extension itself contains zero payment, subscription, billing, license, or upgrade references. No payment platform integrations, no feature gating, no premium tiers. It is a free technical bridge/connector utility. SKB Kontur's web services (Diadoc, Kontur.Extern, etc.) have their own separate paid business plans, but the extension does not gate any functionality behind payment.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The extension is a bridge/connector that only functions on SKB Kontur domains (.kontur.ru, .kontur-ca.ru, .kontur-extern.ru, etc.). These are business SaaS services (electronic document flow, tax reporting, digital signatures) that require user accounts. The extension itself has no login UI or auth mechanism — the login is on the destination Kontur web services.
