Indicates if the connection type is

Implicit SSL

or

Explicit SSL

. The preferred connection type is the more modern Explicit SSL standard, however some trading partners may still require Implicit SSL. If this field is left blank, then the default connection type of Explicit SSL will be used.

Indicates whether SSL or TLS should be used for Explicit SSL connections. TLS is the latest security protocol standard, however many trading partners still use the SSL protocol for Explicit SSL connections. If this field is left blank, then the default security protocol of SSL will be used.

Indicates whether or not to use a clear command channel (CCC) for the FTPS connection. Specify

No

to keep the command channel encrypted. Specify

Yes

to not encrypt the control command channel (however, the actual data transfers will remain encrypted). If neither value is selected, then the default value of

No

will be used.

The data channel protection level indicates if the data channel is encrypted. Select

Private

to keep the data channel encrypted. If the FTPS server does not support an encrypted data channel, select

Clear

to leave the data channel unencrypted. The default setting is Private.

After the command channel is closed, most servers automatically close the SSL/TLS connection, however some servers do not understand the "close_notify" command. Select

No

 to keep

Managed File Transfer

from sending the "close_notify" command. The default value is Yes.

Specify the protocol to use when creating the SSLContext. The value you need to specify here depends on the security providers you have installed in the JRE (Java Runtime Environment). In most cases, the default value (TLS) should just work fine. However, on some IBM JRE implementations the default value would not work if the server you are connecting to does not support TLS 1.0.
