Browser bridge/web extension that enables web pages to interact with a locally-installed Ukrainian digital signature library (EUSign) via native messaging

Enables electronic digital signatures and data encryption in web browsers using Ukrainian CSC (Certificate Service Center) certificates and keys, which is required for Ukrainian e-government, tax reporting, and document signing workflows

User installs native EUSignWeb application + this Chrome extension. When a trusted web page needs digital signing/encryption, the extension acts as a message bridge: the web page sends requests via window.postMessage to the content script, which forwards them to the background script, which communicates with the native signing application via native messaging. The native app handles actual cryptographic operations using the user's locally-stored certificates and keys.

Target users: Ukrainian citizens and businesses using e-government services / Users who need to digitally sign documents via web interfaces / Organizations using Ukrainian CSC (Certificate Service Center) digital certificates

Native application (EUSignWeb) source code not available - cannot confirm if native app has its own login/payment requirements
The extension is tightly coupled with Ukrainian CSC infrastructure; business model of IIT (the vendor) regarding certificates is external to this analysis
Extension is localized in Ukrainian/Russian/English only - limited accessibility for non-Ukrainian users

Monetization

No paid features detected

No billing, subscription, premium, license, upgrade, stripe, payment, or plan-related code found anywhere in the extension source. All 'pro' keyword hits were false positives (protocol, process, Promise, productfiles). The extension is a free utility tool that acts as a browser bridge to locally-installed Ukrainian CSC digital signature software. No feature gating or tier-based functionality detected.

Confidence: 92
Payment platform: --
Source: AI / Medium
Login required: No
Reason: No login UI, authentication forms, credential storage, or account management found in the extension code. All 'auth' keyword hits were false positives referring to 'app_author' (developer name metadata). The extension uses a trusted-sites whitelist model managed locally, not user accounts. The extension is a bridge to a locally-installed native signing application; user identity is established through locally-stored digital certificates/keys, not through login credentials.
