At the risk of sounding dumb and annoying but what is this RSA and prime numbers and all that thing about? I tried to go through the other topic but didn't have time and got lost, I think. It was a while ago. So just thought I'd ask.
As you can probably deduce, this is about RSA Here's the idea. Instead of trying to find primes, what about eliminating many non-primes? the calculation is much faster, since, if you do it in a reasonable way, you are dividing an extremely large number by a fairly small one (probably max of 32768 or so, at least at first) instead of two extremely large ones.

I tried to go through the other topic but didn't have time and got lost, I think. It was a while ago. So just thought I'd ask.The nspire OS is signed with an RSA signature, the base of which is computed off of two very very large prime numbers. Get those prime numbers and you can compute your own, making your own OS for the nspire, but they're ridiculously unfathomably large.
What's an RSA signature? Just like the thing that keeps people from creating new OS's or hacking it or something?
Ah ok, thanks guys.
If you found it and it worked, we wouldn't really care how you got it.
