searching ftp deamon on linux/unix with SSL

["Marco Bano" <Bano () eumetsat de>]

Hi, 

Thanks to all of you, 

I am searching an elegant way (even cheap-commercial) to configure an ftp deamon that authenticate the user on an 
encrypted connection. I read about some "plug-in on wu-ftpd but I forget where...
I want to understand wich ftp client could use SSL or  certificate...

Let me know your experiences and point me to some links.. 

Thanks
