I have written the following code for filling B[] with plaintext in bitsliced form. Since the plaintext is same for each layer, so the approach is pretty straight forward. Please go through and see if its fine for you.
void main()
{
char *plaintext = "hello123";
ARCH_WORD b[64];
char temp;
int i, j, val, cnt;
temp = j = 0;
for(i=0; i<8; i++)
printf("%02x ", plaintext[i]);
printf("\n");
for(cnt =0; cnt < 8; cnt++)
{
for (i=0; i<8; i++)
{
temp = 0x01 & (plaintext[cnt] >> (7 - i));
if (temp == 0)
b[j + i] = 0;
else
b[j + i] = 1;
}
j = j + 8;
i = 0;
}
for (i=0 ;i <64; i++)
printf ("%02x ", b[i]);
}
Cheers,
Deepika
