So factoring a 512 little bit vital would just take about 600 a long time on a Pentium, and about 7 months over the Paragon. But even 1,000,000 Paragons Doing the job with each other would just take six decades to component a 1024 bit vital, and six billion several years to component a 2048 bit essential. If any individual at any time finds a much less difficult strategy to element big numbers, then the RSA program might be damaged.
