Bonjour à tous ,

Je réalise un programme en c++ capable d'envoyer des traps SNMP V3. J'utilise LoriotPro V5 pour les recevoir. Quand je ne met pas de sécurité ça marche bien mais quand je veux réaliser l'authentification dans mon programme me signale que le security name est inconnue.
Voici mon code:

Je ne trouve pas pourquoi?

j'ai trouvé le" problème vient du type d'encryptage du mot de passe qui n'est pas supporté
