AES and Square Attack

How to build the project

mkdir build
cd build
cmake ..
make

The two executables main and main_attack will be generated. These executables are mainly a test of all the others functions together, not a real implementation of the AES to encrypt your own text.

Structure of the project

The functions are split into 3 main .c files. The aes.c file contains the function useful for the AES encryption, the gmath.c file contains essentially the multiplication by x and the multiplication in the Rijndael field and the attack.c file contains the function for the square attack.

Testing with you own values

You can modify the main.c and main_attack.c files with your own values to be sure the implementation works with anything. The variables for the key and the text are easy to find.
