Qt QSslSocket "证书是自签名的，不可信的"

Question

我想连接服务器与QSslSocket和服务器上我得到soketSslError "证书是自签名的，不受信任的"，但我不明白为什么我有这个错误。

第一步是使用openssl为服务器和客户端生成文件

$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

c++ server/client 在服务器:

启动服务器

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();

客户端:

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();
}

，当我从客户端连接时，我得到服务器错误

soket ssl error
"The certificate is self-signed, and untrusted" 
"The certificate is self-signed, and untrusted" 
socketError:  QAbstractSocket::SocketError( 13 ) 

你知道我做错了什么吗?

更新:

Qt Creator 3.0.1基于Qt 5.2.1 (GCC 4.8.2, 64位)

Answer 1

我建议你在服务器上试试:

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

问题已解决

我做了什么:更新版本Qt为5.5并生成新的SSL证书:

openssl req -x509 -newkey rsa:1024 -keyout key.key -out key.pem -days 365 -nodes 

在服务器:

sslServer.setSslLocalCertificate("key.pem");
sslServer.setSslPrivateKey("key.key");
sslServer.setSslProtocol(QSsl::TlsV1_2);

在客户:

sslSocket.addCaCertificates("key.pem");
