We start by analysing the adlit function. All it does is flip the bits of its input, so algebraically, it is equivalent to: adlit (x) = 2^l - 1 - x adlit(x) = 2l −1−x, where l l is the bit length of x x. We can see that this is used to generate the RSA primes; p is generated using getPrime, while q is generated from p using the ...
