YT-Encrypt is a privacy-focused extension for Firefox that encrypts Steam-Tradelinks in YouTube comments, making them accessible only to users of the Sparkles platform. This tool aims to protect users from potential harassment by bots and scammers on Steam by ensuring that the shared links remain secure and confidential. With a straightforward interface, users can easily encrypt their links with just a few clicks.

To use YT-Encrypt, simply navigate to a Sparkles video, click the 'Encrypt' button in the comment section, and paste your Steam-Tradelink. The extension employs RSA-OAEP Encryption for added security. While it provides an essential service for privacy-conscious users, some may experience issues with the button's visibility, which can typically be resolved by refreshing the page.
