QUESTION
Giving N, e, c as follows:
...ANSWER
Answered 2020-Apr-06 at 05:04Thanks for your help! I kown the difficulty to factor a big integer, but this big number appeared in a CTF question.So I think there must be some method to crack it in the limited time. And finally I found the method.The N c e mentioned above is just a half information, and another half of info I got by sql-injection and they are N c1 e1. So the final method to crack it is Common Modulus Attack.So I can get flag by given N e1 e2 c1 c2 without the d1,d2(N=d1*d2)...Thank you guys anyway!
