AES Finder

Utilitaire pour trouver des clés AES dans la mémoire des processus en cours d'exécution. Fonctionne pour les clés 128, 192 et 256 bits.

Utilisation

Ouvrez la solution aes-finder.sln dans Visual Studio 2013 pour compiler le source. Vous pouvez aussi utiliser gcc/clang :

g++ -O3 -march=native -fomit-frame-pointer aes-finder.cpp -o aes-finder

Pour rechercher des clés dans le processus dont l'ID = 123, exécutez :

aes-finder.exe -123

Pour rechercher des clés dans tout processus nommé chrome.exe, exécutez :

aes-finder.exe chrome.exe

Vous pouvez maintenant voir quels types de clés AES sont utilisés dans votre application préférée !

Remarques

ne fonctionne pas sur les clés AES whitebox
un binaire 32 bits ne peut rechercher que dans les processus 32 bits, un binaire 64 bits peut rechercher dans les deux – 32 et 64 bits
« clé de chiffrement » signifie que cette clé peut être utilisée pour le chiffrement ou le déchiffrement
« clé de déchiffrement » signifie que cette clé est très probablement utilisée uniquement pour le déchiffrement
sur Linux nécessite un noyau au moins v3.2 (appel système process_vm_readv)
