Not sure what cracking option i should use -_-

[mkcon]

don't laugh mkcon but how do i give you the first 512 bytes of the file or whatever. Do i just open it in notepad and copy the code? I have never done that before :/

No. These bytes are binary values.
Download HxD (a free hex editor). Open the container in it, mark the first 512 bytes and copy them to a new file. This file you can send to me.
