I don't have in-depth knowledge of the encryption-scheme used in CuteFTP Pro...
But how about this:
There is a possibility to export the sites in CuteFTP Pro as a plain text format file..
Here's snip of the online-helpfile:
Exporting your Site Manager Listings
CuteFTP Pro also allows you to export your Site Manager listings as a text file, in two different formats. You may export the listings as URLs only, or as a more detailed listing of hostnames, directories and descriptions. These text files can be very useful. For example, the exported text files can be sent to friends who use other FTP clients or used to create a Web page of links. NOTE: Passwords will also be exported and will be plainly visable!
Comment anyone?
