be attempting to factor a 315,653 digit number. Factoring of 150k
digit numbers is nothing new in the 21st Century. :)
As to the RSA comparison... When you're willing to put up $20k in
prize money, I suspect you'll get people trying to factor your
number. But if you do, make certain to post a reasonable challenge
and/or a reasonable reward. The next RSA challenge (RSA-640, $20k
prize) is only 193 digits with factors estimated at 85-88 digits.
While the RSA-1024 challenge is 309-digits with a $100k prize. So I
figure you'll need about $250k as a prize to get anyone to take your
challenge very seriously.
