Re: How to encrypt panels, libraries and scripts?
Hello,
there are some tools in WinCC OA which can be used for encryption of scripts or panel.
You will find detailed information about this topic in the WinCC OA help (Special functions / Encryption of Panels and CTRL-Scripts) or you search for "encryption".

Be aware that when you encrypt a panel, there is no way to decrypt it! So make sure that you make a copy of the panels before encrypting them.

Re: How to encrypt panels, libraries and scripts?
The best approach is:
- put your script code in libraries
- panels should only contain shapes and some function calls
- Encrypt your libraries
- Do not encrypt your panels !!!!!
The fact that you can't decrypt the panel doesn't have to be a problem. The real risk that you run is the fact that you don't see that the panel is encrypted. The extension is still *.pnl.
That is : i recently ran into a project and had to change a panel. I then found out that the panel was encrypted and that I had to reverse-engineer the panel just by looking at the shapes.
Good luck
