On general comment. The amount of parameters you pass to the method are a lot. Would you be able to be woken up in the middle of the day/night (whatever is less comfortable) and would you know the parameters? Did you consider passing them as a struct? > +static void check_ls_64(uint8_t bytes) > +{ > + /* calculate various adjustment constants (number of bits, bytes, octets etc.) > + based on number of bytes in type we actually test */ I was more thinking about what exactly do you want to test? Encode/Decode being compatible with each other? Corner cases? This is very difficult to understand code and I don't see your intend. I wonder/guess that there is a more simple approach to it. > int main(int argc, char **argv) > { > - uint8_t out[ARRAY_SIZE(input)]; > + uint8_t out[ARRAY_SIZE(input)], test[8]; > unsigned int offs; > > - for (offs = 0; offs < sizeof(out); offs++) { > + srand(time(NULL)); > + > + for (offs = 0; offs < sizeof(out); offs++) > + { coding style. :) > - if (memcmp(start, exp_out + offs, len)) { > + if (memcmp(start, exp_out + offs, len)) > + { coding style. :) > + if (0 != memcmp(s, p, 2)) > + { coding style. :) > +void _kasumi_kgcore(uint8_t CA, uint8_t cb, uint32_t cc, uint8_t cd, const uint8_t *ck, uint8_t *co, uint16_t cl); sorry.
