não consigo usar de jeito nenhum no TJSP. Alguma dica de quem consegue utilizar?

Edson Carvalho2025年6月22日

Não está funcionando no site do tjsp, não é possível a assinatura. Acabo tendo que levar no OAB para assinar. Se alguém conseguir resolver manifeste-se.

Anderson Natilus2025年6月1日

Não consegui fazer funcionar no Linux. No Firefox instala, mas aparece o certificado ao clicar sobre a extensão, mas no site do TJSP não carrega.

Everytime I see this logo my head aches. Poorly tested software, filled with bugs

Como faz pra o site de notas fiscais ler os certificados se essa extensao nao funciona no mac, e o proprio chrome store diz que a extensao nao segue as regras? era para ser uma extensao de segurança.

Atendeu minha necessidade. Porém requer um pouco de conhecimento em informatica.

Vinícius Alves2024年6月24日

Funciona? Não. Os desenvolvedores ligam? Também não.

AI product read

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.

Target users: 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

Monetization

No paid features detected

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.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: No
Reason: 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.
