LCS USB Token WebSocket Client

A Node.js client library for interacting with USB tokens via WebSocket, version 1.3.0. Developed by LCS, it provides methods to connect to a WebSocket server, check health, verify PIN, list connected USB tokens, and sign documents. The library exposes a CommonJS API with callbacks, and appears to be focused on LCS-CA hardware tokens commonly used in Vietnamese digital signing. The package has no recent updates and minimal documentation, limited to a single README with example usage.
