The way the Client deals with security is dealt with on this set of preferences.

• Key Bits - How many bits the Public/Private keypair must have.  The higher this is, the more secure, but you pay the penalty as the encryption & decryption times will increase
• Key Length - Defines the length of the Public/Private Keypair.  The lengthier this is, the more secure, but you pay the penalty as the encryption & decryption times will increase
• Generate New Keypair -   This will generate a new keypair for your client to use effective immediately.  This cannot be used whilst you are connected to an FTP site, as your encryption keypair will go out of synch with the server
• Clear Keypair -  This is if you wish to not have a keypair for the moment.  This option is pretty much redundant
• Mask Passwords -  This option will mask the passwords with asterisks (*) in the log file and on screen.  If you wish your password to be visible in the log file and on screen (for troubleshooting purposes) you can turn this feature off.
• Super Safe mode -  The key pairs are not written to disk (eftp3client.ini) and therefore is more secure
• New Keypair on Startup -  This will make the client generate a new public/private keypair when it is launched
• Default Anon Password - This is the password the client will try to use by default when connecting to sites anonymously
• Protect Restore -  Checking this box will make EFTP request a password when you try to restore it from the system tray.  This is useful if you are transferring many files and wish that nobody else can see what your client is doing by restoring the application.  For example, if you are uploading/downloading sensitive data and you have a visitor in your office, you can protect your activities using this feature.

The status at the bottom of the screen (currently Idle) is the current status of the Encryption engine. This will change when you are generating a new keypair according to it's current activity.  This is informational only.
