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.
