Hello

 

Can some one suggest a proper solution to prevent hack attempts in Flash games where scores are submitted to a PHP layer.

 

thanks
MRS

    Hi,

     

    a long time ago (using as1/2 rather than as3) I came up with this solution:

    the game contains a "mild" hard-coded encryption layer (i.e. rather than adding parts of a key variable to something,

    and using another part of a key var as a shift count, the code contains add 0x53 or shift by 3)

    This encryption function is added to a raw movie on the server, and matched to a php session var

     

    Rationale to do that: I found that there were many more experts on using a decompiler, than on following web data

    (there was no Charles readily available at that time, either). Surely finding that the reverse-engineered game could

    not even talk to the server should be discouraging
