Description

I was developing jsleak during most of my free time for my own need.It is easy-to-use command-line tool designed to uncover secrets and links in JavaScript files or source code. The jsleak was inspired by Linkfinder and regexes are collected from multiple sources.

Features:

• Discover secrets in JS files such as API keys, tokens, and passwords.
• Identify links in the source code.
• Complete Url Function
• Concurrent processing for scanning of multiple Urls
• Check status code if the url is alive or not
