How you inject codes?

Are you sure you done all of this for AES?
AES has complicated implementation because of its references to S_Boxes...

I use delphi. The origin delphi source of AES is from http://www.secureblackbox.com, named elaes.pas. You can google it.

With the techniqe described above, I get the 128bit AES in asm.
Now the limit is length of the crypt key you input and crypt data must <= 16 byte.(due to my lazy)

You know, Cpu not know function, procedure, S_Boxes..., it just know dword, address. So S_Boxes is a relative address map of dword data for Cpu view and asm.
