UI Elements for FTP SSL Settings
The following tables describe the UI elements that are available on the feature page and in the Actions pane.
Feature Page Elements
Element Name |
Description |
||
---|---|---|---|
SSL Certificate |
Specifies the SSL certificate that you want to use for SSL.
|
||
View |
Opens the Certificate dialog box for the selected certificate. |
||
Allow SSL Connections |
Select this setting to allow data encryption for both the control channel and data channel when an SSL certificate is selected. |
||
Require SSL Connections |
Select this setting to require data encryption for both the control channel and data channel when an SSL certificate is selected. Note SSL requires additional processor time and slows down data transmissions because of the additional encryption data that must be transmitted. |
||
Custom |
Select this setting to customize the individual data encryption requirements for the control channel and data channel when an SSL certificate is selected. Note Selecting the Custom option enables the Advanced button; clicking Advanced will display the Advanced SSL Policy dialog box. |
||
Use 128-bit encryption for SSL connections |
Select this setting to require stronger encryption. You can use 128–bit SSL to help secure transmissions between your FTP server and clients in either an intranet or internet environment. Note 128–bit SSL requires more processor time and slows down data transmissions more than the 40–bit version does. This setting is because 128–bit SSL transmits additional encryption data to provide stronger encryption. Therefore, before requiring 128–bit SSL, make sure that your data transmissions need stronger encryption. |
