H4CK1NG G00GL3 - Ep 005 Ch 002: Project Zero Adventure

HACKING GOOGLE is a documentary of Google’s cybersecurity teams and H4CK1NG G00GL3 is it’s CTF counterpart. Project Zero Adventure is a cryptography challenge I wrote. In the game, the players control the Security Princess to dodge the obstacles and catch the bugs (a variant of Google Chrome’s dinosaur game). After that, the server will sign messages consisting of the players' name and the score via the `/sign` API. The players will then submit it to the `/highscore` API. If the score submitted to the highscore API is negative, they will be given the flag. However, there is one catch: The server is only willing to sign the results with non-negative scores.
