version Qt: 5.8.0Qt C++ SSL/TLS serveur avec Python client
Python version: 2.7.13
version OpenSSL: OpenSSL 1.0.1c
Système d'exploitation: Windows 10
J'essaie de créer un serveur SSL/TLS g Qt C++ et un client écrit en Python. J'utilise le projet exemple sslechoserver fourni avec Qt. Pour un exemple de client Python, j'utilise celui que j'ai obtenu de cette documentation Python: https://docs.python.org/2/library/ssl.html. J'ai copié le CERT de l'exemple de serveur mentionné ci-dessus et l'ai placé à côté du script Python et spécifié que dans les scripts de test j'ai essayé.
J'ai également essayé divers exemples de clients Python J'ai trouvé sur internet (comme ici: https://carlo-hamalainen.net/blog/2013/1/24/python-ssl-socket-echo-test-with-self-signed-certificate), mais aucun n'a été en mesure de se connecter pleinement au serveur d'écho Qt (il n'a jamais imprimé client connecté: comme il le fait quand j'utilise l'exemple sslechoclient qui a également été livré avec Qt). Le client dans le lien ci-dessus fonctionne avec le serveur Python à partir du même lien, donc je sais qu'il fonctionne toujours avec quelque chose.
