Comment on Overclocking SSLparentComments−john_nl15yI'm also curious where the 30x comes from. If cost is indeed the square of key size I would expect: Cost(1024) = (1024*x)^2 Cost(2048) = (2048*x)^2 = (2*1024*x)^2 = 4 * (1024*x)^2 Which is a 4x increase in cost, not 30x.−illumin815yCube, not square. Also, implementation matters.2^3, or 8 times more expensive.
