This is a Chrome extension (Manifest V3) that integrates with the 115.com cloud storage service. It allows users to export download links from their 115 cloud files directly to an aria2 RPC download manager, or to generate text-based download commands for aria2, IDM, or plain links. The extension injects a UI overlay into the 115 web interface (both old and new UI versions) to select files and trigger downloads. It supports recursive folder traversal, SHA1 checksum verification, configurable RPC endpoints, and optional encrypted API calls for premium users. The architecture consists of a background service worker (background.js) that handles messaging, cookie retrieval, and HTTP requests; content scripts (start.js, 115.js, 115_new.js) that run in the context of 115.com pages to intercept file data and communicate with the extension; and a set of library modules (core.js, store.js, ui.js, downloader.js, secret.js) that manage configuration, UI rendering, and download logic. The extension uses a custom RSA-based encryption scheme (secret.js) to interact with 115's pro API for premium download links.
