    Hi

    That's not possible, its the idea behind encryption.

    I can create a skill program and password protect it.

    Only people with the password can load it and use it. So offcourse, they cannot decrypt it and take others IP.

    The documentation also states that one should always keep a copy of the original data. 

    Best regards

    Hello Ejlersen ,

    thanks for your feedback, someone one tell me the pretty print function may solve this question, But I don't know how to use it.

    THe below is I found in Cadence help,

    The pprint function is useful, for example, when printing out a long list where print simply prints the list on one (possibly huge) line but pprint limits the output on a single line and produces a multiple-line printout if necessary. This multiple-line printout makes later input much easier.

    If you have any idea, please feel free to let me know

    Best regards Andy

    Hi

    If a skill file is password encrypted there's no way back.

    In my opinion that's the correct way, its the only way I can protect my IP - same goes for everyone else who's made skill programs.
