WebFeb 19, 2024 · BabyRSA (UIUCTF2024) — e and m too small for a large public key First look at the code encryption, e is quite small for a large n , a 4096-bit key. Yet the … WebMar 5, 2024 · The solution goes on by signing each individual integers and assign their signature in a,b,c,d. s(m) = a*b*c*d % n we can get the value of n by sending the key P to the server which gives us publickey (n,e). Once we calculated the signature,we can send hex value of m and s (m) to retrieve the flag. Solution:
