Encryption with a dongle is no longer classified as a secure encryption method.
It is recommended to encrypt with certificates instead.
If the Enforce encryption of downloads, online changes, and boot applications option is selected in the Security Screen view in the Security Level group, then the encryption technology is set to Encryption with certificates and cannot be changed in this dialog.

No Encryption | |
Simple Encryption | You can download the boot application to the controller only when the defined dongle (license key) is connected to the computer. The dongle is provided by CODESYS GmbH or by the respective hardware manufacturer. The firm code is displayed. Specify the supplied product code. |
Encryption with license management | You can download the boot application to the controller only after you have specified the product code and firm code, and the respective dongle is connected to both the development computer and the controller. You receive the codes from the vendor which manages the licenses. |
Encryption with certificates | You can download the boot application to the controller only when a valid certificate exists for it. The Certificates group is enabled. See the description below. The option is already selected if the Enforce encryption of downloads, online changes, and boot applications option is selected on the User tab of the Security Screen view. You can also select the Digitally sign application code option. |
Sign with certificate | You can download the application code to the controller only if it has been signed with a valid certificate. Encryption is not necessary in this case. |
Note: If the Enforce encryption of downloads, online changes, and boot applications option is selected in the Security Screen view in the Security Level group, then the encryption technology is set to Encryption with certificates and cannot be changed in the Properties dialog. | |
| The Certificate Selection dialog opens. Here you can select previously installed certificates of devices for which the encryption of download, online change, and boot application is enabled. The list can contain multiple entries if multiple devices are authorized to run this application. |
Digitally sign application code | The application is signed with a digital signature. The certificate for the digital signature is specified in the Security Screen view on the User tab. |
