Unprotecting Protected AutoLISP file

Discussion in 'AutoCAD' started by Jean-Paul Lanaux, Jun 18, 2004.

  1. I am a 4th year computer science student. I have a file with I am
    assuming (PROTECTED) vlx extension with the following header:

    VRTLIB-1, .... FAS4-FILE; Do not change it! ....

    I attempted to decompile it with a few of the utilities on the net, but
    was unsuccessful.

    I would like to study some of the code. Also,

    A few questions:

    Does any one know which tool could be used to decompile?

    I would like to learn more about this intermediate process (compiling),
    can someone provide a link to resources about this intermediate step?

    Yhanking you in advance,

    This is illegal in most countries.

    Good. That's the way it's intended to work.

  4. Could you expand on your statement and provide more details?

    What exactly is illegal? decompiling or attempting to decompile? Please
    explain.

  5. Not good, I have what I am looking for. Piece of cake.

    Protection Intentions: GOOD
    reality: NOT GOOD

    BTW don't dispair, What I am looking for by reading other peoples code
    is harmless. I am attempting knowledge, nothing else. I promise to be a
    good boy.

    Not that I believe that you are really interested in legal matters,
    but here you have a link to the §§s of the German "Urheberrecht" (I am
    living in Germany), which is the corresponding thing to the US
    copyright: http://transpatent.com/gesetze/urhg11.html#69e

    This §69e is saying that you are ONLY allowed to decompile a program
    without permission by the author, when the code needs to be modified
    to make it "interoperate" with other programs or with other hardware,
    AND when the nessesary information to achieve this interoperatibilty
    can not be obtained by other way, AND when you you decompile and
    modify only that part of the code, which needs to be modified.

    In the rare cases where you are allowed to decompile the code (in your
    case you are not), you are not allowed to use the information which
    you get by decompiling the code to create similar programs.
