+   Présentation de la track LabOps de PolyPwn 2026. L'objectif est de faire un keygen pour une application web de gestion de laboratoire compilée en WebAssembly (WASM). L'application comporte plusieurs pages, chacune nécessitant une licence différente (Bronze, Silver ou Gold). Il faut donc créer un générateur de clés capable de produire une licence valide pour chaque niveau afin d'obtenir les flags.
