Web-FTP is a Perl/CGI FTP client.
Crypto card support allows people to connect to ftp servers that use crypto card security. Lemme know if it works for you.
Web-FTP is a fully featured ftp client designed for secure file management when used in conjunction with an SSL enabled web server.
As a secondary function it can serve as an FTP client for users who's firewalls block FTP, since all communication is through the HTTP protocol.
Once you log in to Web-FTP it retains a session, which runs locally on your server, subsequent calls to the cgi (with the proper cookie) reconnect you to your session, therefore maintaining state.
Since everything passes through a cgi, if you put that CGI on a secure web-server you will have secure ftp (as long as the ftp is the same machine as the http server, or is behind a firewall).
