high-performance, portable C++ library providing data structures and algorithms for manipulating signed, arbitrary length integers, and for vectors, matrices, and polynomials over the integers and over finite fields.

I have been using it a lot because of the Cryptography class that I’m in this semester, and something that I need to do frequently is generate random numbers.

To do this, seeding is frequently required, and the NTL is no different, but it took a while for me to actually get it to work. The following will seed the random functions provided by the NTL ZZ class:

ZZ number, seed;
srand(getpid());
seed << ((long) GetTime() ^ rand());
SetSeed(seed);
RandomLen(number, rand() % 300);

Stick that at the top of your main() and you should be all set.

Also, does anyone know of a shorter, possibly easier to remember, way to do this? If so, the comments are open.

Note: All of the old files that were originally located directly off of the index (i.e. content.php), are now located in the old/ directory (so, now that link is located at old/content.php), but all folders have remained in the same place (i.e. TEST/test5.php is still located exactly there).

On a side note, I am still indeed working on Project GOTO. I am working out kinks in the mail program so that bots don’t use it to spam (this is why my feedback form is now disabled). I expect to have a new release in a few weeks.
