MuscleCard pour la carte étudiante
''MuscleCard is an open source project hosted at the M.U.S.C.L.E website. It aims to develop a JavaCard applet and supporting middleware to perform cryptographic operations like signing and encryption in a smart card.'' http://www.openscdp.org/scripts/musclecard/index.html

Installation
Deplacer le fichier CardEdge.cap dans le dossier de GPShell et lancer le script suivant mode_211 gemXpressoPro enable_trace establish_context card_connect select -AID a000000018434d open_sc -security 3 -keyind 0 -keyver 0 -key 47454d5850524553534f53414d504c45 // Open secure channel install -file CardEdge.cap -sdAID A000000018434D00 -nvCodeLimit 4000 card_disconnect release_context

Initialisation
Comme spécifié ici, l'applet à besoin d'être initialisé (par exemple avec opensc): opensc-tool -s 00:A4:04:00:06:A0:00:00:00:01:01 \ -s B0:2A:00:00:38:08:4D:75:73:63:6C:65:30:30:04:01:08:30:30:30:30:30:30:30:30:08:30:30:30:30:30:30:30:30:05:02:08:30:30:30:30:30:30:30:30:08:30:30:30:30:30:30:30:30:00:00:17:70:00:02:01
