We have n,e,dp,c. Assume that it is quite difficult to factorize n, but it can be easily divided in fact. What can we do with dp leak? dp ≡ d mod (p-1 阅读全文

This is the problem that requires some math skills. We have p,q,dp,dq,c. Now let's start to solve it. dp ≡ d mod(p-1) dq ≡ d mod(q-1) m ≡ c^d mod n m 阅读全文

The solution is based on the fact that we have got the source code.However, how could I get the source code? So, this one is to broaden my web knowled 阅读全文
