4096 bit keys

[Mike Acker]

with chip makers playing with chips having 64 cores printed in silicon...

someplace i read the ratios on this,-- if you make the key a little
longer the key gets much harder to break.  in public key encryption
though you have to factor the product of the two large prime numbers --
which i'm told is no easy task.  i've often wondered about this as lists
of large prime numbers are not hard to come by... so-- start someplace
and start running divides... trouble is though you can't use the
hardware instruction set: the numbers are way to large

what does an x64 chip do? divide a 64 bit integer into a 128 bit
dividend to yield a 64 but quotient and a 64 bit remainder? dunno but
you have to do the same thing but using what? a 2048 or 4096 bit dividend?

(I'm not a mathematician)

what if they put 8192 cores on a chip? who would have such a machine?
NSA.  the smart money would bet they would have it
