includes/rijndael.h Defines the Rijndael algorithm.

includes/rijndeal_field.h Defines the field arithmetic for the GF(256) Rijndael uses.

rijndael.c Implements the Rijgndael algorithm.

AesMain.c Tests the Rijndael algorithm on known test vetors.

rijndael.c Implements the field arithmetic.

The BinaryGalois directory contains old code. It is a quick implmentation that I am using to implement better code.

BinaryGalois/includes/gf_8bit.h Defines the polynomial for the Rijndael GF(256)

BinaryGalois/gf_8bit.c Defines the field arithmetic over GF(256) used for the Rijndael algorithm.

BinaryGalois/RijndaelData.c Defines the GF(256) used for the Rijndael algorithm. RijndaelByPower[1] shows that the field is generated by 0x3, with the reduction being 0x100=0x1b, so all field elements are between 0x00 and 0xff.

BinaryGalois/includes/Rijndael.h Defines the key expansion, encryption, and test functions.

BinaryGalois/Rijndael.c Implements the key expansion, AES encryption, and test functions.

BinaryGalois/gfMain.c Provides a main function to run the test function.
