Drizz's BigNum Library

[Ghandi]

Hi again,

I'm trying to use Drizz's BigNum library and it hangs on "bnRsaGenPrime", so i assembled one of the examples he's included. It has the same issue, simply never succeeding in generating a prime. This is different behaviour than the pre-assembled exe that is in the package, it works fine, so i was wondering whether anybody has had any success in using this lib? If you read this Drizz, any insight would be greatly appreciated. :)

It seems that its getting stuck in a loop while executing:

Code Select Expand


@@: invoke bnAddDw,bn,2
@@Test:
invoke bnTrialDivpt,bn ;Test primality of number with division, never returns other than FALSE
test eax,eax
jz @B
invoke bnFermatpt test eax,eax
jz @B

Yes you are right, there seems to be something different when the lib is compiled with jwasm.
Until I figure out what is wrong use the attached one.

Thank you for your speedy reply Drizz, i just tested the lib and it works fine. I thought i was something i had done wrong, which is what confused me when it was also having trouble with your example code. I didnt want to bother you with a PM, that is why i posted in the forum.

found it, jwasm generates wrong code for:

Code Select Expand

.if !ABS_BN_IS_ONE(esi)
.endif
