I noticed that solutions to Set 1 Challenge 1 in languages other than C++ all 404. Does that mean that no one has contributed solutions? If so, how can I contribute?
Another problem is that every time we've talked about posting solutions, people have asked us to hold off.
Finally, a quick jab: thousands and thousands of people completed several sets of these challenges --- more than a thousand got through the CBC padding oracle, which (in our challenge) is cryptographically more complicated than the TLS POODLE attack. None of them had solutions. You don't need them either. :)
