By using , you can establish a direct encrypted connection between two browsers.
One of the significant challenges in web development is transferring large files securely and efficiently. Traditional methods of file transfer, such as email attachments or FTP, are often insecure and unreliable. However, with the use of modern web technologies, it is possible to transfer large files securely and for free. The "60 HTML CSS JS Projects" repository includes several projects that demonstrate how to achieve this. By using , you can establish a direct
