Encrypting the boot project
 | Requirement: A current version of Windows or TwinCAT/BSD® on the target system Encryption is not supported by older operating systems such as Windows NT, Windows CE / Windows Embedded Compact. |
The encryption of the boot project is set (on the target-system) in the root node of the PLC project.
- A user database is selected (and valid) in TwinCAT Engineering.
- The project must be linked with the user database as information from the user database is used for encryption.
- 1. Double-click on the PLC project object in the PLC project tree in the Solution Explorer.
- The PLC project settings are opened in an editor.
- 2. In the Project tab, select the Encrypt boot project entry in the drop-down list of the Encryption setting.
- The boot project is stored encrypted on the target system when it is activated for the target system.
| Neither a user database nor an OEM certificate is required for decryption of the boot project on the target system. |
