Digital signing bridge for Vietnamese educational management software

Vietnamese educational platforms need digital signing (ký số) capabilities that interface with local USB tokens or smart cards; this extension bridges web-based educational systems to a native signing host application

User logs into an educational management platform → Platform detects extension via sessionStorage flag 'ext-vsigner' → User initiates signing → Platform sends signing data via window.postMessage → Content script relays to background script → Background forwards to native host 'com.qi.vsigner' via sendNativeMessage → Native host performs cryptographic signing (likely with USB token) → Result flows back: native host → background → content → web page

Target users: Teachers and educational staff using Vietnamese school management systems / Administrators on qlgd.edu.vn and truongdientu.vn platforms / Users who need to digitally sign educational documents via USB token or smart card

Cannot verify if destination educational platforms actually require login (inferred from domain types)
Cannot verify if the native host application (com.qi.vsigner) has paid features or requires license
Extension has no popup UI - it is purely a bridge/connector

Monetization

No paid features detected

No payment, billing, subscription, upgrade, or license code found in the extension. The 'pro' keyword matches are false positives from JavaScript Promise constructors and base64-encoded metadata. The extension is a pure bridge/connector with no feature gating.

Confidence: 90
Payment platform: --
Source: AI / Medium
Login required: Yes
Reason: The extension itself does not implement login, but its core workflow requires the user to be logged into Vietnamese educational management platforms (edu.vn, qlgd.edu.vn, truongdientu.vn, etc.) to initiate digital signing operations. These platforms require user accounts for document management and signing.
