AI 产品解读Browser extension that enables digital signature operations (PDF signing, CAdES, hash signing) in web pages by bridging the browser with a native cryptographic component installed on the user's computer
Enables web-based digital document signing and certificate operations without requiring Java. Replaces Java applets that were previously used for browser-based digital signatures with a modern browser extension + native component architecture.
1. Install native component on PC from websigner.softplan.com.br. 2. Import PFX certificate or configure PKCS#11 crypto device. 3. Navigate to a web page that uses the Web PKI SDK. 4. The web page JavaScript calls the extension via custom events. 5. Extension routes the request to the native component via native messaging. 6. Native component performs crypto operations (signing, certificate listing). 7. Results returned to the web page.

- 目标用户
- Brazilian users needing digital signatures for government/legal documents / Users of web applications that integrate Lacuna Web PKI SDK / Professionals requiring digital document signing in the browser
- Cannot fully inspect the minified main.js (Angular app) for hidden features, but popup is just a shell loading the Angular app
- The extension requires a separate native component installation - full functionality cannot be assessed from extension alone
- Cannot verify if the REST PKI service (Lacuna Software) has its own paid tiers independent of the extension

The heuristic keywords are false positives. 'subscribe' appears in SignalR promise library (programming pattern). 'upgrade' appears in polyfill code (JS polyfill upgrades). 'purchase' appears in scripts/lib.d.ts SDK documentation - this describes the Lacuna Web PKI SDK license that developers building websites must purchase to use the library; it is NOT about the extension end-user paying for features. The extension itself has no payment UI, no premium features, no subscription flow, no billing integration.

- No login, account creation, or authentication flow found in the extension. The 'token' keyword hits refer to PKCS#11 cryptographic hardware tokens (SafeNet USB devices), not authentication tokens. The 'auth' hits refer to authorizing websites to perform digital signatures, not user authentication. No password fields, no user account system, no credentials required to use the extension.
