comment Common modulus attack on RSA when the 2 public exponents differ by a single bit
still didn't get it, say e and e2 can be divided by n, how come e-e2 can be divided by n as well? i can't see the relationship between e-e2 and n...

sorry for my stupid question, why n can be divided by e-e2?, is that a property? or can it prove?

Thanks for your answer , may i know why gcd(e,e2) = gcd(e,e-e2)

that's cool! spending some time, finally understand what do you mean, may i have one more follow up, why Euler toient function of N, must be even number?

thx for your answer. i didn't get what this mean "e is relatively prime to ϕ(N)" can you illustrate by a simple example?
