Qt & SSL, Handshake failed
c++, openssl, qt, ssl, windows-7
Solution
You could ignore certificate verify using QSslConfiguration::setPeerVerifyMode():
QSslConfiguration conf = request.sslConfiguration();
conf.setPeerVerifyMode(QSslSocket::VerifyNone);
request.setSslConfiguration(conf);
Problem
I have a problem. I've made a Qt application which is connecting to a https site. On my working machine, everything works fine. When I try to test my application on a clean Windows 7 machine, I observed the following issue: After I have installed a fresh Win7 machine (installed all updates), after starting my application, I get a SSL Handshake failed error, SIGNAL(sslErrors(QNetworkReply*,QList)) is emitted with two empty error strings and error = QSslError::NoError. I was really searching the whole day why this happens, also could reproduce it with examples\network\securesocketclient\release\securesocketclient and domain "google.com". Now, I found out, that once I have started the internet explorer accessing https://www.google.com, my application is also working as expected and no further handshake errors are coming. BTW, it does not matter which site you are accessing - this is not related to google.com. Can someone explain to me why this happens? Is it a bug in OpenSSL, or Qt, or both? UPDATE I found a way to live with that issue for myself, implementing the following ignore logic: ``` QSslError ignoreNOErrors(QSslError::NoError); foreach(QSslError error, errors) if(error.error() != QSslError::NoError) qDebug() << error.errorString(); QList<QSslError> expectedSslErrors; expectedSslErrors.append(ignoreNOErrors); reply->ignoreSslErrors(expectedSslErrors); ``` Thanks
