Three necessary steps : 1 - The code you want to hide must reside in a package, i.e. hidden code functionalities will be accessible to your users via a Needs["HiddenCode"] or a Get["HiddenCode"] or a <<"HiddenCode" This implies you have to write and document your code juste like any library is written and documented. 2 - Elements in your library that are exported should have the attribute "ReadProtected" set. Consequently, the Mathematica code used to define your objects cannot be read. 3 - Finally, the file "HiddenCode.m" containing your code should be encrypted via the built-in function Encode. You can add further restrictions : Encode in respect to a certain key or to a certain machine for instance. While some weakness in this model might still exist (I don't see how for instance the value of a private variable is hidden by this mechanism - but I admit I did not investigate the subject), in pratice it is rock solid, transparent to your users, and easy to implement. jmt
