AI 产品解读Bridge/connector extension that enables web applications to access locally installed ICP-Brasil digital certificates via Chrome's native messaging API for legally valid digital signatures under Brazilian law.
Web applications cannot directly access digital certificates stored on the user's workstation. This extension solves the bridge gap between AssinaWeb (a digital signature web app) and local ICP-Brasil certificate stores, enabling legally compliant digital signatures from the browser.
1. User installs the native host app (gercertdigital.exe) on their workstation. 2. User installs this Chrome extension. 3. User navigates to AssinaWeb or a compatible web application. 4. The web app dispatches a custom DOM event (br.com.integral.CertHandler.RequestEvent) with signing parameters (text, certificate serial, PIN, etc.). 5. The content script captures the event and relays it to the background service worker. 6. The service worker forwards the request to the native host application via chrome.runtime.connectNative. 7. The native app accesses the local certificate store and performs the cryptographic signing. 8. Results flow back through the native port → service worker → content script → custom DOM event to the web page.

- 目标用户
- Brazilian users who need to digitally sign documents using ICP-Brasil certificates / Organizations using AssinaWeb for document signing workflows / Legal and compliance professionals requiring digital signatures with legal validity in Brazil
- Cannot confirm whether AssinaWeb (the destination service) requires login or has paid plans from the extension source alone.
- The native host application source is not included, so the actual certificate interaction logic cannot be verified.
- Only 4 source files to analyze; the extension is minimal by design as a bridge component.
付费分析未识别到付费功能
No payment code, subscription logic, premium feature gating, license checking, or upgrade UI exists in the extension. The 'pro' keyword match is a false positive from a base64 hash in verified_contents.json. The extension is a free bridge utility.

- The extension itself has no login UI, no authentication code, no account system. It is a pure bridge/connector between a web application and local digital certificates. The 'pin' field in contentScript.js (line 7) refers to a digital certificate PIN, not a user account login. The extension relays messages without any authentication gating.
