Zero estrelas. Assinar algo exige PhD em TI. Ridículo. Suporte ZERO. Tutoriais = ZERO. Que horror!!!!

Parem de prejudicar as pessoas, parem com a politicagem.

Infelizmente, uma dor de cabeça. Algo que era para ajudar, apenas toma tempo. Não tem suporte, não tem informação.

Lima2025年1月27日

Durante minha experiência, informo que esta extensão não funciona em todos os navegadores, Desde que adquiri o certificado digital da Certisign, esta extensão nunca conseguiu acessar meu certificado digital A3-Token. E o pior, ninguém realiza modificações na extensão com o objetivo de realizar manutenções, corrigir bugs, etc.

Extension to use digital certificates within webpages

AI product read

Browser bridge extension enabling digital document signing via native cryptographic operations for the Certisign platform

Enables digital signatures in web browsers without deprecated Java applets by bridging web applications to native cryptographic APIs and hardware security devices (smartcards, tokens)

User installs extension + native messaging host (br.com.certisign.websigner). On the Certisign platform or any integrated web app, the web page sends signing requests via custom DOM events. The content script bridges these to the extension's service worker, which communicates with the native host to access local certificate stores and perform cryptographic operations (signing, certificate reading). Results are returned to the web page.

Target users: Brazilian users and organizations using Certisign digital certificates / Users of portaldeassinaturas.com.br document signing platform / Users with hardware cryptographic tokens (SafeNet, smartcards)

No login/payment flows found in extension source, but the destination service (portaldeassinaturas.com.br) behavior was not directly auditable
The main.js file is a large bundled Angular app (~970KB) and was only partially examined via keyword search
The 'license' concept could be confusing — it refers to a developer SDK license (B2B) rather than an end-user subscription, which required careful source analysis to distinguish

Monetization

No paid features detected

The extension itself is free to install and use with no in-extension payment gates, upgrade prompts, or subscription flows. The 'license' concept in the code (lib.d.ts lines 7-9, event-page.js line 39/631-652) refers to a B2B developer-facing WebPKI SDK license key that web application developers purchase from Lacuna Software to integrate the signing API into their websites — not a user-facing subscription. The 'subscribe' keyword in main.js is Angular RxJS observable.subscribe() (programming pattern). The 'pro' matches are from words like 'problema', 'produced', 'provide' in Portuguese/Spanish locale strings. Digital certificates from Certisign are an external product sold separately, not a feature of the extension.

Confidence: 80
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension itself does not implement any login UI, authentication flow, or user account system. It is a passive bridge/SDK that responds to requests from web pages. The content script listens for custom DOM events from web pages and forwards them to the native messaging host. No login-related code (auth endpoints, credential storage, OAuth flows) exists in the extension source. The destination service (portaldeassinaturas.com.br) may require account access, but the extension itself gates no functionality behind login.
