The file aesopt.h is assumed to be included before this header file. + * If there are no global variables, the definitions here can be used to put + * the AES tables in a structure so that a pointer can then be added to the + * AES context to pass them to the AES routines that need them. If this + * facility is used, the calling program has to ensure that this pointer is + * managed appropriately. In particular, the value of the t_dec(in, it) item + * in the table structure must be set to zero in order to ensure that the + * tables are initialised. In practice the three code sequences in aeskey.c + * that control the calls to aes_init() and the aes_init() routine itself will + * have to be changed for a specific implementation. If global variables are + * available it will generally be preferable to use them with the precomputed + * FIXED_TABLES option that uses static global tables. + * + * The following defines can be used to control the way the tables + * are defined, initialised and used in embedded environments that + * require special features for these purposes + * + * the 't_dec' construction is used to declare fixed table arrays + * the 't_set' construction is used to set fixed table values + * the 't_use' construction is used to access fixed table values + * + * 256 byte tables: + * + * t_xxx(s, box) => forward S box + * t_xxx(i, box) => inverse S box + * + * 256 32-bit word OR 4 x 256 32-bit word tables: + * + * t_xxx(f, n) => forward normal round + * t_xxx(f, l) => forward last round + * t_xxx(i, n) => inverse normal round + * t_xxx(i, l) => inverse last round + * t_xxx(l, s) => key schedule table + * t_xxx(i, m) => key schedule table + * + * Other variables and tables: + * + * t_xxx(r, c) => the rcon table + */ + +/* + * OpenSolaris OS modifications + * + * 1.
