Marin Secret
The primes used for the modulus N is of the form 2 ^ x - 1. Such primes are called Mersenne’s primes, named after French mathematician Marin Mersenne. A quick hack for factorisation is to lookup FactorDB, as I assume the primes are studied extensively. The result from FactorDB shows two primes $2^{2203}-1$ and $2^{2281}-1$ Another solution involves a bit of math. Suppose the two primes used are $2 ^ a - 1$ and $2 ^ b - 1$, and $a \leq b$....
