AI 产品解读Bridge extension for Japanese Government Electronic Procurement System (GEPS) enabling electronic certificate-based authentication and digital signing via IC cards and certificate files
Government procurement portals (geps.go.jp, p-portal.go.jp) require electronic certificate-based login and document signing that cannot be handled by standard browser capabilities alone. This extension acts as a bridge between the web portal and a native messaging application that interfaces with physical IC card readers and certificate files.
User navigates to the GEPS or Procurement Portal website → The content script detects the sign_client_extension meta tag and listens for GepsMainCtrl custom events → When the portal needs certificate operations (login, signing), it dispatches events → The content script forwards requests to the background script → The background script communicates with the native messaging host (jp.go.geps.getcertcrypt) → The native app interfaces with the IC card reader or certificate file → Results are relayed back through the extension to the web portal

- The extension's description explicitly states it is for '電子証明書によるログイン、署名等を行うためのアプリケーション' (an application for login and signing using electronic certificates) on the government procurement portals (geps.go.jp, p-portal.go.jp). The extension bridges the browser to a native messaging host (jp.go.geps.getcertcrypt) that retrieves certificates from IC cards (My Number, JPKI, GPKI) and performs digital signatures. These government portals require certificate-based authentication to access procurement workflows.
