Qt QSslSocket "The certificate is self-signed, and untrusted" - c++

Question

i want to connect server with QSslSocket and on server i get soketSslError "The certificate is self-signed, and untrusted" , but i dont understand why i have this error.
On first step was generated file for server and client with openssl
$openssl req -new -newkey rsa:1024 -keyout ca.key -x509 -days 500 -out ca.crt
$openssl req -new -newkey rsa:1024 -keyout client01.key -out client01.csr
$openssl ca -config ca.config -in client01.csr -out client01.crt -batch
in c++ server / client
On server:
start server
if (listen(QHostAddress::Any,this->connectingPort)) {
std::cout<<"Server start on port: "<<this->connectingPort<<std::endl;
return true;
} else {
std::cout<<"Cant start server. "<<errorString().toStdString().c_str()<<std::endl;
return false;
}
incomingConnection
QFile keyFile("ca.key");
if (!keyFile.open(QIODevice::ReadOnly)) {
delete this->sslSocket;
qDebug()<<"Cant open file: "<<keyFile.fileName();
return false;
}
QByteArray pasp ="qwerty";
QSslKey key(keyFile.readAll(),QSsl::Rsa,QSsl::Pem,QSsl::PrivateKey,pasp);
if (key.isNull()) {
delete this->sslSocket;
qDebug()<<"key in file "<<keyFile.fileName()<<" is empty";
return false;
}
keyFile.close();
this->sslSocket->setPrivateKey(key);
this->sslSocket->setPeerVerifyMode(QSslSocket::VerifyPeer);
this->sslSocket->setLocalCertificate("ca.crt");
this->sslSocket->startServerEncryption();
on client side:
this->sslSocket->setPeerVerifyMode(QSslSocket::VerifyPeer);
QFile keyFile("client01.key");
if (!keyFile.open(QIODevice::ReadOnly)) {
delete this->sslSocket;
qDebug()<<"Cant open file: "<<keyFile.fileName();
return ;
}
QByteArray pasp ="qwerty";
QSslKey key(keyFile.readAll(),QSsl::Rsa,QSsl::Pem,QSsl::PrivateKey,pasp);
if (key.isNull()) {
delete this->sslSocket;
qDebug()<<"key in file "<<keyFile.fileName()<<" is empty";
return ;
}
keyFile.close();
this->sslSocket->setPrivateKey(key);
this->sslSocket->setLocalCertificate("client01.crt");
this->sslSocket->connectToHostEncrypted("192.168.0.10",1258);
if (!this->sslSocket->waitForEncrypted()) {
qDebug()<<"error: "<<sslSocket->errorString();
}
and when i connecting from client i get on server error
soket ssl error
"The certificate is self-signed, and untrusted"
"The certificate is self-signed, and untrusted"
socketError: QAbstractSocket::SocketError( 13 )
any idea what i do wrong?
UPDATE:
Qt Creator 3.0.1
Based on Qt 5.2.1 (GCC 4.8.2, 64 bit)

Answer 1

I suggest you try this on the server:
QList<QSslCertificate> cert = QSslCertificate::fromPath(QLatin1String("your-certificate.pem"));
QSslError error(QSslError::SelfSignedCertificate, cert.at(0));
QList<QSslError> expectedSslErrors;
expectedSslErrors.append(error);
this->sslSocket.ignoreSslErrors(expectedSslErrors);

Answer 2

probleb has been resolved
what i doen:
update version Qt for 5.5
and generated new ssl certificate:
openssl req -x509 -newkey rsa:1024 -keyout key.key -out key.pem -days 365 -nodes
in server:
sslServer.setSslLocalCertificate("key.pem");
sslServer.setSslPrivateKey("key.key");
sslServer.setSslProtocol(QSsl::TlsV1_2);
in client:
sslSocket.addCaCertificates("key.pem");
