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

Target users: Japanese government procurement officials / Private sector contractors bidding on government contracts / Users of the Japanese Government Electronic Procurement System (GEPS) and Procurement Portal (p-portal.go.jp)

Chrome Web Store detail page was unavailable, so store description/reviews/screenshots could not be consulted
The native messaging host application (jp.go.geps.getcertcrypt) source is not included in the extension package - its behavior is inferred from the message protocol
Cannot verify if the native host itself has any licensing or paid components

Monetization

No paid features detected

No evidence of any paid features, payment processing, subscriptions, or premium tiers. This is a government utility extension that bridges the browser to a native messaging host for electronic certificate operations. The native host (jp.go.geps.getcertcrypt) handles IC card reader interactions for free government services.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: Yes
Reason: 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.
