 Welcome to the OWASP WrongSecrets game! The game is packed with real life examples of how to _not_ store secrets in your software. Each of these examples is captured in a challenge, which you need to solve using various tools and techniques. Solving these challenges will help you recognize common mistakes & can help you to reflect on your own secrets management strategy.
