To view/change your global security preferences, open the Preferences
dialog by selecting Tools -> Preferences
(JFTP -> Preferences
on Mac OS X) menu item from the menu bar. Click on the Connection Settings
-> Security
category in the left frame. This will display the existing
security preferences.
Do Not Use SSL
Select this radio button to use plain TCP/IP connection. All commands and data
will be sent un-encrypted when this option is selected.
Use SSL If Available
Select this radio button to tell JFTP to use a secured connection if the server
you are connecting to supports SSL. If the server supports SSL, all commands
and/or data will be transferred in encrypted format.
Use Explicit SSL
Select this radio button to tell JFTP to use an Explicit SSL connection. This
means, after connecting to the FTP server, JFTP will negotiate for an SSL connection
and if it succeeds, the plain TCP/IP connection will be transformed into an
SSL connection. If the SSL negotiation fails for any reason, the connection
will be closed.
Use Implicit SSL
Select this radio button to connect to the FTP server using an implicit SSL
connection.
Do Not Encrypt Data Channel
Select this option to instruct JFTP not to use SSL for transferring actual data
such as file transfers and directory listings.
When you are done, click on the Save
button to save all your
changes. This would also close the Preferences
dialog.
