Newbie with potential ECC protection

[chants]

In general we take a white-box approach to reverse engineering. You took much more of a black-box or grey-box approach and this seems to becoming a very popular method in the cryptography field. Software trace comparison, software fault injections, etc. But there is no one approach best suited for every sample you find out there. You have to study it and come up with the fastest attack plan route. Be it inductive or deductive strategies

I appreciate your comments.
My math is good but not great. This was fairly easy to solve, only maybe 12 total hours. Good challenge though.
