FTP over SSL in AIX (UNIX)

Folks over at SO couldn't answer this, so I am posting over here. I need to do an FTP over SSL to a FileZilla Server running on a Windows server from an AIX Unix clien. I have the Host name of the destination server, the user id and password, and an SSL certificate. I am not sure how to install that certificate in AIX. When I do an ftp command (using the below code) from Unix it does connect successfully to the Filezilla server and I am able to do get and or mget. But, I am not sure if that is happening over SSL since I haven't installed the SSL Certificate yet. Do I need to install the Certificate in the Unix box (AIX)? if yes, then how? (specific steps and commands) and how to utilize the installed SSL certificate to do FTP after the installation? $ ftp XXX.XXX.XXX.243 Connected to XXX.XXX.XXX.243. 220-FileZilla Server version 0.9.24 beta 220-written by Tim Kosse 220 Please visit http://sourceforge.net/projects/filezilla/ Name (XXX.XXX.XXX.243:littercat): joyride 331 SSL required Password: 230 Logged on ftp> Note: SSH (SFTP/SCP) is not an option and it has to be FTP over SSL/TLS only (From AIX UNIX to Windows FileZilla).
