Security

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.
