[Batch] Sécurité du script

Il n'y a malheureusement aucun moyen vraiment sûr.

Tu peux compiler ton code en exe ou essayer de cacher ton code dans un pseudo cryptage, mais ces 2 solutions sont facilement crackable.

Je poste ici ,un code HTA fait par mon ami Delmar Grande, de cryptage de fichier bat.

Ça peut faire l'affaire si on a à faire à des utilisateurs lambda. :mouarf:
