Project encryption on a target device
Encrypt projects on any device with FactoryTalk Optix Update Server installed.
Encryption scope
Project
YAML
files, which represent the project information model, are transferred as encrypted binary files to target devices. For more information, see Project source format.By default, Emulator components are encrypted. You cannot disable the encryption of Emulator components.
Encryption operation
Target devices generate symmetric encryption keys based on the current hardware, independently from the host platform. The encryption key is stored in
EncryptionKey.bin
on the target device in the Runtime
folder. The encrypted application is tied to the specific target device hardware.You cannot copy and run an encrypted project on a different target device. Exporting a project to a USB device or folder does not encrypt the compiled project.
TIP:
To upload an encrypted project, you need to:
- Upload the project withTransfer application source filesselected for the target device. See Add a target device.
- Use the password of the local user of the target device that transferred the application.
TIP:
Project encryption is not related with the
FactoryTalk Hub
account. You can upload encrypted projects from a device while opening a project even if you are not logged in or are logged into a different organization than the organization used to develop the project.encryption
