Remarques

Lorsque vous spécifiez true pour le paramètre, la leaveStreamOpen fermeture du SslStream n’a aucun effet sur le innerStream flux ; vous devez fermer innerStream explicitement lorsque vous n’en avez plus besoin.

Si aucune valeur n’est spécifiée dans le fichier de configuration pour encryptionpolicy, la EncryptionPolicy valeur par défaut EncryptionPolicy.RequireEncryption est pour le SslStream instance qui est construit.

L’utilisation du chiffrement Null est requise lorsque la stratégie de chiffrement est définie sur EncryptionPolicy.NoEncryption.

Remarques

Lorsque vous spécifiez true pour le paramètre, la leaveStreamOpen fermeture du SslStream n’a aucun effet sur le innerStream flux ; vous devez fermer innerStream explicitement lorsque vous n’en avez plus besoin.

L’argument userCertificateValidationCallback du certificateErrors délégué contient tous les codes d’erreur Windows retournés par l’interface SSPI (Security Support Provider Interface) du canal. La valeur de retour de la méthode appelée par le délégué détermine si l’authentification userCertificateValidationCallback réussit.

Le protocole de sécurité et les algorithmes de chiffrement sont déjà sélectionnés lorsque la userCertificateValidationCallback méthode du délégué est appelée. Vous pouvez utiliser la méthode pour déterminer si les algorithmes de chiffrement et les forces sélectionnés sont suffisants pour votre application. Si ce n’est pas le cas, la méthode doit revenir false pour empêcher la SslStream création de .

Si aucune valeur n’est spécifiée dans le fichier de configuration pour encryptionpolicy, la EncryptionPolicy valeur par défaut EncryptionPolicy.RequireEncryption est pour le SslStream instance qui est construit.
