How to Encrypt SKILL File

EMperson

I have a SKILL file I want to encrypt. I found an encrypt function, but I don't understand how it works. Any advice, or sample code/pseudo-code would be great.

    It depends why you are wanting to encrypt the code. Use the encrypt command to encrypt the code so that a password is needed to run it. This offers some protection for your IP but not much. You then need to use "load" with the password option. Probably what you want to do is create a context file. Check out the documentation for this and ask if you can't get it to work.

    So a few things...

    1) I want my user to be able to use my SKILL code, but not view it or change it. I don't know if the encrypt function should be inside the file I want to encrypt, or in a different file?

    2) You mentioned that the encrypt command does not really protect my IP.. why is that?

    3) What is a better way of encrypting my SKILL file?

    Thank you so much!!

    If you use encrypt your users won't be able to easily read or edit the file. The encryption is very basic so a keen user would be able to read the code if they know what they're doing I think.

    You encrypt to a different file from the original.

    Creating a context file provides much better security if you are worried about IP.
