Récupération du résultat d'un batch vers une variable VBS

**Always01** · 20/02/2015, 09h59

Bonjour à tous.

Je fait mes premiers pas en vbs et je me retrouve face à un dilemme. Notre parc informatique est exclusivement composé d'ordinateur de la marque Dell. Ces machines disposes-donc d'un service TAG (composé de 7 caractères), que l'on peux se procurer via la commande MS-DOS "wmic bios get serialnumber". Je dispose d'un vbs de hashage MD5 (ici) avec lequel j'aimerai hasher la chaîne de caractère issue du batch de génération du service TAG.

Cela est-il possible?

Je vous remercie d'avance.

Bien cordialement

Re-Bonjour,

Dernière petite question après je vous embête plus ! Sur le résultat du hachage c'est possible d'afficher seulement les 6 premiers caractères ?

Encore merci en tout cas.

Cordialement

Sur le résultat du hachage c'est possible d'afficher seulement les 6 premiers caractères ?

Juste par curiosité expliquez-moi comment vous allez exploiter ce script dans votre boite ?

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
MsgBox "Le numero de serie du BIOS ==> " & serial & vbCrlf & "Hash BIOS ==> " & MD5FileHash(serial) & vbcrlf &_
 "Les 6 premiers caracteres du hachage ==> " & Left(MD5FileHash(serial),"6"),Vbinformation,"Le numero de serie du BIOS"

Surtout n'oubliez pas mes +1

Parfait merci beaucoup ! En faite nous allons changer de stratégie de sécurité pour les sessions admin locale, les pass seront les 6 premiers caractères du résultat du hachage md5 du service TAG de l'ordinateur (donc des pass unique). En tout cas c'est vraiment sympa d'avoir aidé et ce de manière rapide et efficace !

Cordialement
