Using a clear data channel with SSL 

Using CDC (Clear Data Channel) speeds up transfers with SSL sites. A clear data channel 

encrypts the connection process, but files are transferred without encryption. You can add 

more speed to your transfers by using a clear command channel as well. 

1.  Select a site in the Site Manager.  

2.  From the menu choose File > Properties. The Site Properties dialog box appears. 

3. Select 

the 

Type tab. 

4. In 

the 

Protocol list, select  FTP with SSL (Implicit encryption), or FTP with 

SSL (Explicit encryption) or FTP with SSL/TLS (AUTH TLS). 

5. Select 

the 

Clear Data channel check box. 

6. Select 

OK or Connect. 

Note: 

The Clear Data channel option is only available with SSL connections. 

Using a clear command channel with SSL 

Using CCC (Clear Command Channel), your connection process and login are encrypted, 

but when you begin transferring data, all FTP commands are sent in clear text. The data 

transfers remain encrypted, unless you choose to use a clear data channel.  SSL connections 

require CCC when connecting in PORT mode from behind a NAT firewall.
