    Encryption Help

    I am working on re-creating a map for a game that uses a code basically the same as C, however I have run into a problem. The original author gave me all the code, but past that is not willing to help.

    There is a decent size method for encrypting data in this, and I have all of the code, but am not sure exactly what is going on, I would love to convert it to a small C program where I could enter the desired values, and it would put them into the encryption for me, but this is beyond me, if anyone is interested in helping, reply here or email me criscocube@gmail.com
    thanks!

    (I can't post the code here first, because it exceeds post length, and second because I don't know if the original author wants it to be open source particularly).


    Thanks in advanced!


    Edit:

    here is the start of the encryption function, just so you have an idea what I'm talking about:

    The only thing you need to change in that code to make it C, is to change your array declarations.

    From:
    Code:
    int[64][4] k;
    int[8][4] init;
    To:
    Code:
    int k[64][4];
    int init[8][4];
    If you understand what you're doing, you're not learning anything.

    Moved to correct forum.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
