It requires the C files ; aeskey.c and aestab.c for support. ; ; Adapted for TrueCrypt: ; - Compatibility with NASM and GCC ; ; An AES implementation for x86 processors using the YASM (or NASM) assembler. ; This is an assembler implementation that covers encryption and decryption ; only and is intended as a replacement of the C file aescrypt.c. It hence ; requires the file aeskey.c for keying and aestab.c for the AES tables. It ; employs full tables rather than compressed tables. ; This code provides the standard AES block size (128 bits, 16 bytes) and the ; three standard AES key sizes (128, 192 and 256 bits). It has the same call ; interface as my C implementation. The ebx, esi, edi and ebp registers are ; preserved across calls but eax, ecx and edx and the artihmetic status flags ; are not. It is also important that the defines below match those used in the ; C code. This code uses the VC++ register saving conentions; if it is used ; with another compiler, conventions for using and saving registers may need to ; be checked (and calling conventions). The YASM command line for the VC++ ; custom build step is: ; ; yasm -Xvc -f win32 -o "$(TargetDir)\$(InputName).obj" "$(InputPath)" ; ; The calling intefaces are: ; ; AES_RETURN aes_encrypt(const unsigned char in_blk[], ; unsigned char out_blk[], const aes_encrypt_ctx cx[1]); ; ; AES_RETURN aes_decrypt(const unsigned char in_blk[], ; unsigned char out_blk[], const aes_decrypt_ctx cx[1]); ; ; AES_RETURN aes_encrypt_key(const unsigned char key[], ; const aes_encrypt_ctx cx[1]); ; ; AES_RETURN aes_decrypt_key(const unsigned char key[], ; const aes_decrypt_ctx cx[1]); ; ; AES_RETURN aes_encrypt_key(const unsigned char key[], ; unsigned int len, const aes_decrypt_ctx cx[1]); ; ; AES_RETURN aes_decrypt_key(const unsigned char key[], ; unsigned int len, const aes_decrypt_ctx cx[1]); ; ; where is 128, 102 or 256. In the last two calls the length can be in ; either bits or bytes. ; ; Comment in/out the following lines to obtain the desired subroutines. These ; selections MUST match those in the C header file aes.h ; %define AES_128 ; define if AES with 128 bit keys is needed ; %define AES_192 ; define if AES with 192 bit keys is needed %define AES_256 ; define if AES with 256 bit keys is needed ; %define AES_VAR ; define if a variable key size is needed %define ENCRYPTION ; define if encryption is needed %define DECRYPTION ; define if decryption is needed %define AES_REV_DKS ; define if key decryption schedule is reversed %define LAST_ROUND_TABLES ; define if tables are to be used for last round ; offsets to parameters in_blk equ 4 ; input byte array address parameter out_blk equ 8 ; output byte array address parameter ctx equ 12 ; AES context structure stk_spc equ 20 ; stack space %define parms 12 ; parameter space on stack ; The encryption key schedule has the following in memory layout where N is the ; number of rounds (10, 12 or 14): ; ; lo: | input key (round 0) | ; each round is four 32-bit words ; | encryption round 1 | ; | encryption round 2 | ; .... ; | encryption round N-1 | ; hi: | encryption round N | ; ; The decryption key schedule is normally set up so that it has the same ; layout as above by actually reversing the order of the encryption key ; schedule in memory (this happens when AES_REV_DKS is set): ; ; lo: | decryption round 0 | = | encryption round N | ; | decryption round 1 | = INV_MIX_COL[ | encryption round N-1 | ] ; | decryption round 2 | = INV_MIX_COL[ | encryption round N-2 | ] ; .... .... ; | decry
