Hello,

Is there any native support in WinCC OA to encrypt the information the config file?

No, an encryption of the information in the config file is not possible.

For your own managers you can store encrypted values. Is there specific information which you want to have encrypted?

Gert-Jan,

Sometimes sensitive information has to be stored in the config file. I understand that we can devise a method for encrypting that information for our own managers, drivers and even control scripts (and we do if necessary) but as you are aware we also make use of special managers (Archie & SQLviaDP) which we have no control over but also need sensitive information stored in the config file. I was kind of hoping that a method was available that would also make this possible for managers that are out of our control.

Thanks and with kind regards,
Jan

you can use CtrlCrypt and the functions aes256Encrypt/aes256Decrypt and store everything together with a secrect key in a crypted library

In case you only need to prevent distributing the sensitive information to all DesktopUIs & MobileUIs, you could store this information in a separate config file like 'config.archie' and start this manager with this additional config file '+config config.archie'.
