0d179a0e7d POLY: don't clamp polyonmial in build_polynom()
Otherwise we might hit problems when using this as an
out-polynom in a arithmetic functions. The caller can clamp
it himself, if he needs so.

f8cac1553f ALL: set context members to unsigned int 2014-05-12 20:17:42 +02:00
fc4ee3b70b POLY: add build_polynom() method
We can build a polynom via an array of integers or just an empty
one, so that it is initialized and properly allocated.

417ce9c0f2 RAND: use unsigned long instead of mp_digit
if we use mp_set_int() instead of mp_set(), then we can use
full unsigned long integers instead of single digits. This
seems a lot safer, especially for future versions of the
random algorithm.

04d5d6d38f rand:ntru_get_rnd_poly_small: written a function to generate a random polynom
like get_urnd_int_small but with the random source from /dev/random
instead of /dev/urandom

71b8f4cbeb Added static mp_digit get_rnd_int_small(int *sign)
but it takes about ~40minutes to generate a x^500
polynom with /dev/random.

4030335661 POLY: implemented pb_normalize
normalizes a polynom by defining a numerical range
for each factor of a polynom.
