Is Learn Helper safe?
Learn Helper stores auto-login credentials reversibly in local browser storage with a hardcoded XOR key.
When its auto-login helper is enabled, Learn Helper reads the username and password entered on the Tsinghua login page and saves them in chrome.storage.local after XOR-encoding them with a hardcoded key. The extension later decodes those saved values with the same key to fill or perform automatic login, so the stored credentials are reversible rather than strongly protected.
