Secure FTP Applet is a secure FTP client component that runs within the context of your web browser as a Java applet. Secure FTP Applet can establish a connection using either standard FTP, SFTP (FTP over SSH) or the FTPS (FTP over SSL) protocols for a secure connection. It is designed to let non-technical users exchange data with an FTP server while ensuring that all data exchanged is completely secure.
