Tiny ECC

Being Smart will mean completely different if you can use special numbers!

Files given:

The challenge requires us to enter values such that , are prime, then asks us to solve the elliptic curve discrete log problem over on the curve . However since the check doesn't take mod , we can just set such that we end up solving the discrete log problem on , which has a map to via .
