When entering certain text arguments in expressions you can choose to encrypt the text in order to prevent readability. This mainly applies to arguments like username and password, e.g. as for the ExecuteCommand function.

When you start to type in an argument which is supported by the encryption feature, a pane opens showing the command "Encrypt text". If you want to encrypt the text, then just click on "Encrypt text". Another dialog will open with an entry field for the argument. Enter the argument and click on <OK>.

Instead of the readable text a generated string of characters with the prefix encrypted_ will be entered as argument in the function.
