AES256 algorithm

[Salim Zaabi]

Hi Everybody,
I have a project which I have to build my own AES256 algorithm. Does anyone have any idea how to do that or where is the good source to implement the idea??

Here is a description of the algorithm:

I hope you are just doing this for an academic project or just for fun.

Rule #1 of applying cryptography: NEVER EVER implement your own encryption algorithm!! This is true even if you are following a well defined standard like AES. You must use an implementation that has been fully tested and peer reviewed. Your code will have bugs in it, some that you could never conceive of. Someone will find a way to crack it and exploit your errors.

Thanks for your advice my friend RedSon....
