Detailed Description

The QSslSocket class provides an SSL encrypted socket for both clients and servers.

Since
4.3
Note
This class or function is reentrant .
Attention
Module: QtNetwork

QSslSocket establishes a secure, encrypted TCP connection you can use for transmitting encrypted data. It can operate in both client and server mode, and it supports modern SSL protocols, including SSLv3 and TLSv1. By default, QSslSocket uses TLSv1, but you can change the SSL protocol by calling setProtocol() as long as you do it before the handshake has started.

SSL encryption operates on top of the existing TCP stream after the socket enters the ConnectedState. There are two simple ways to establish a secure connection using QSslSocket : With an immediate SSL handshake, or with a delayed SSL handshake occurring after the connection has been established in unencrypted mode.

The most common way to use QSslSocket is to construct an object and start a secure connection by calling connectToHostEncrypted() . This method starts an immediate SSL handshake once the connection has been established.

QSslSocket *socket = new QSslSocket ( this );
connect (socket, SIGNAL ( encrypted ()), this , SLOT (ready()));
socket-> connectToHostEncrypted ( "imap.example.com" , 993);

As with a plain QTcpSocket , QSslSocket enters the HostLookupState, ConnectingState, and finally the ConnectedState, if the connection is successful. The handshake then starts automatically, and if it succeeds, the encrypted() signal is emitted to indicate the socket has entered the encrypted state and is ready for use.

Note that data can be written to the socket immediately after the return from connectToHostEncrypted() (i.e., before the encrypted() signal is emitted). The data is queued in QSslSocket until after the encrypted() signal is emitted.

An example of using the delayed SSL handshake to secure an existing connection is the case where an SSL server secures an incoming connection. Suppose you create an SSL server class as a subclass of QTcpServer . You would override QTcpServer::incomingConnection() with something like the example below, which first constructs an instance of QSslSocket and then calls setSocketDescriptor() to set the new socket's descriptor to the existing one passed in. It then initiates the SSL handshake by calling startServerEncryption() .

void SslServer::incomingConnection( int socketDescriptor )
{
QSslSocket *serverSocket = new QSslSocket ;
if (serverSocket-> setSocketDescriptor (socketDescriptor)) {
connect (serverSocket, SIGNAL ( encrypted ()), this , SLOT (ready()));
serverSocket-> startServerEncryption ();
} else {
delete serverSocket;
}
}

If an error occurs, QSslSocket emits the sslErrors() signal. In this case, if no action is taken to ignore the error(s) , the connection is dropped. To continue, despite the occurrence of an error, you can call ignoreSslErrors() , either from within this slot after the error occurs, or any time after construction of the QSslSocket and before the connection is attempted. This will allow QSslSocket to ignore the errors it encounters when establishing the identity of the peer. Ignoring errors during an SSL handshake should be used with caution, since a fundamental characteristic of secure connections is that they should be established with a successful handshake.

Once encrypted, you use QSslSocket as a regular QTcpSocket . When readyRead() is emitted, you can call read() , canReadLine() and readLine() , or getChar() to read decrypted data from QSslSocket 's internal buffer, and you can call write() or putChar() to write data back to the peer. QSslSocket will automatically encrypt the written data for you, and emit encryptedBytesWritten() once the data has been written to the peer.

As a convenience, QSslSocket supports QTcpSocket 's blocking functions waitForConnected() , waitForReadyRead() , waitForBytesWritten() , and waitForDisconnected() . It also provides waitForEncrypted() , which will block the calling thread until an encrypted connection has been established.

QSslSocket socket;
socket. connectToHostEncrypted ( "http.example.com" , 443);
if (!socket. waitForEncrypted ()) {
qDebug () << socket. errorString ();
return false ;
}
socket. write ( "GET / HTTP/1.0\r\n\r\n" );
while (socket. waitForReadyRead ())
qDebug () << socket. readAll (). data ();

QSslSocket provides an extensive, easy-to-use API for handling cryptographic ciphers, private keys, and local, peer, and Certification Authority (CA) certificates. It also provides an API for handling errors that occur during the handshake phase.

The following features can also be customized:

The socket's cryptographic cipher suite can be customized before the handshake phase with setCiphers() and setDefaultCiphers() . The socket's local certificate and private key can be customized before the handshake phase with setLocalCertificate() and setPrivateKey() . The CA certificate database can be extended and customized with addCaCertificate() , addCaCertificates() , setCaCertificates() , addDefaultCaCertificate() , addDefaultCaCertificates() , and setDefaultCaCertificates() .
Note
If available, root certificates on Unix (excluding Mac OS X) will be loaded on demand from the standard certificate directories. If you do not want to load root certificates on demand, you need to call either the static function setDefaultCaCertificates() before the first SSL handshake is made in your application, (e.g. via "QSslSocket::setDefaultCaCertificates(QSslSocket::systemCaCertificates());"), or call setCaCertificates() on your QSslSocket instance prior to the SSL handshake.

For more information about ciphers and certificates, refer to QSslCipher and QSslCertificate .

Enumerations

◆ PeerVerifyMode

Describes the peer verification modes for QSslSocket .

Since
4.4

The default mode is AutoVerifyPeer, which selects an appropriate mode depending on the socket's QSocket::SslMode.

  • VerifyNone QSslSocket will not request a certificate from the peer. You can set this mode if you are not interested in the identity of the other side of the connection. The connection will still be encrypted, and your socket will still send its local certificate to the peer if it's requested.
  • QueryPeer QSslSocket will request a certificate from the peer, but does not require this certificate to be valid. This is useful when you want to display peer certificate details to the user without affecting the actual SSL handshake. This mode is the default for servers.
  • VerifyPeer QSslSocket will request a certificate from the peer during the SSL handshake phase, and requires that this certificate is valid. On failure, QSslSocket will emit the QSslSocket::sslErrors() signal. This mode is the default for clients.
  • AutoVerifyPeer QSslSocket will automatically use QueryPeer for server sockets and VerifyPeer for client sockets.

  • UnencryptedMode The socket is unencrypted. Its behavior is identical to QTcpSocket .
  • SslClientMode The socket is a client-side SSL socket. It is either alreayd encrypted, or it is in the SSL handshake phase (see QSslSocket::isEncrypted() ).
  • SslServerMode The socket is a server-side SSL socket. It is either already encrypted, or it is in the SSL handshake phase (see QSslSocket::isEncrypted() ).

    Returns this socket's current cryptographic cipher suite.

(i.e., the first cipher in the list is the most preferred cipher). The session cipher will be the first one in the list that is also supported by the peer.

    By default, the handshake phase can choose any of the ciphers supported by this system's SSL libraries, which may vary from system to system. The list of ciphers supported by this system's SSL libraries is returned by supportedCiphers() . You can restrict the list of ciphers used for choosing the session cipher for this socket by calling setCiphers() with a subset of the supported ciphers. You can revert to using the entire set by calling setCiphers() with the list returned by supportedCiphers() .

    You can restrict the list of ciphers used for choosing the session cipher for all sockets by calling setDefaultCiphers() with a subset of the supported ciphers. You can revert to using the entire set by calling setCiphers() with the list returned by supportedCiphers() .

    Definition: qabstractsocket.cpp:2550

    Starts an encrypted connection to the device hostName on port , using mode as the OpenMode .

    This is equivalent to calling connectToHost() to establish the connection, followed by a call to startClientEncryption() .

    QSslSocket first enters the HostLookupState. Then, after entering either the event loop or one of the waitFor...() functions, it enters the ConnectingState, emits connected() , and then initiates the SSL client handshake. At each state change, QSslSocket emits signal stateChanged() .

    After initiating the SSL client handshake, if the identity of the peer can't be established, signal sslErrors() is emitted. If you want to ignore the errors and continue connecting, you must call ignoreSslErrors() , either from inside a slot function connected to the sslErrors() signal, or prior to entering encrypted mode. If ignoreSslErrors() is not called, the connection is dropped, signal disconnected() is emitted, and QSslSocket returns to the UnconnectedState.

    If the SSL handshake is successful, QSslSocket emits encrypted() .

    QSslSocket socket;
    connect (&socket, SIGNAL ( encrypted ()), receiver, SLOT (socketEncrypted()));
    socket. connectToHostEncrypted ( "imap" , 993);
    socket-> write ( "1 CAPABILITY\r\n" );

    Note: The example above shows that text can be written to the socket immediately after requesting the encrypted connection, before the encrypted() signal has been emitted. In such cases, the text is queued in the object and written to the socket after the connection is established and the encrypted() signal has been emitted.

    The default for mode is ReadWrite .

    If you want to create a QSslSocket on the server side of a connection, you should instead call startServerEncryption() upon receiving the incoming connection through QTcpServer .

    4.4

    The written parameter contains the number of bytes that were successfully written.

    See also
    QIODevice::bytesWritten()

    This function writes as much as possible from the internal write buffer to the underlying network socket, without blocking.

    If any data was written, this function returns true; otherwise false is returned.

    Call this function if you need QSslSocket to start sending buffered data immediately. The number of bytes successfully written depends on the operating system. In most cases, you do not need to call this function, because QAbstractSocket will start sending data automatically once control goes back to the event loop. In the absence of an event loop, call waitForBytesWritten() instead.

    This method tells QSslSocket to ignore only the errors given in errors .

    This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

    Since
    4.6

    Note that you can set the expected certificate in the SSL error: If, for instance, you want to connect to a server that uses a self-signed certificate, consider the following snippet:

    QList<QSslCertificate> cert = QSslCertificate::fromPath ( QLatin1String ( "server-certificate.pem" ));
    QSslError error ( QSslError::SelfSignedCertificate , cert. at (0));
    QList<QSslError> expectedSslErrors;
    expectedSslErrors. append ( error );
    QSslSocket socket;
    socket. ignoreSslErrors (expectedSslErrors);
    socket. connectToHostEncrypted ( "server.tld" , 443);

    Multiple calls to this function will replace the list of errors that were passed in previous calls. You can clear the list of errors you want to ignore by calling this function with an empty list.

    This slot tells QSslSocket to ignore errors during QSslSocket 's handshake phase and continue connecting.

    If you want to continue with the connection even if errors occur during the handshake phase, then you must call this slot, either from a slot connected to sslErrors() , or before the handshake phase. If you don't call this slot, either in response to errors or before the handshake, the connection will be dropped after the sslErrors() signal has been emitted.

    If there are no errors during the SSL handshake phase (i.e., the identity of the peer is established with no problems), QSslSocket will not emit the sslErrors() signal, and it is unnecessary to call this function.

    Warning
    Be sure to always let the user inspect the errors reported by the sslErrors() signal, and only call this method upon confirmation from the user that proceeding is ok. If there are unexpected errors, the connection should be aborted. Calling this method without inspecting the actual errors will most likely pose a security risk for your application. Use it with great care!

    Returns true if the socket is encrypted; otherwise, false is returned.

    An encrypted socket encrypts all data that is written by calling write() or putChar() before the data is written to the network, and decrypts all incoming data as the data is received from the network, before you call read() , readLine() or getChar() .

    QSslSocket emits encrypted() when it enters encrypted mode.

    You can call sessionCipher() to find which cryptographic cipher is used to encrypt and decrypt your data.

    Returns the peer's digital certificate (i.e., the immediate certificate of the host you are connected to), or a null certificate, if the peer has not assigned a certificate.

    The peer certificate is checked automatically during the handshake phase, so this function is normally used to fetch the certificate for display or for connection diagnostic purposes. It contains information about the peer, including its host name, the certificate issuer, and the peer's public key.

    Because the peer certificate is set during the handshake phase, it is safe to access the peer certificate from a slot connected to the sslErrors() signal or the encrypted() signal.

    If a null certificate is returned, it can mean the SSL handshake failed, or it can mean the host you are connected to doesn't have a certificate, or it can mean there is no connection.

    Since
    4.4

    The error is usually an indication that QSslSocket is unable to securely identify the peer.

    This signal provides you with an early indication when something's wrong. By connecting to this signal, you can manually choose to tear down the connection from inside the connected slot before the handshake has completed. If no action is taken, QSslSocket will proceed to emitting QSslSocket::sslErrors() .

    Returns the socket's verify mode.

    Since
    4.4

    This mode mode decides whether QSslSocket should request a certificate from the peer (i.e., the client requests a certificate from the server, or a server requesting a certificate from the client), and whether it should require that this certificate is valid.

    The default mode is AutoVerifyPeer, which tells QSslSocket to use VerifyPeer for clients and QueryPeer for servers.

    Returns the socket's cryptographic QSslCipher {cipher}, or a null cipher if the connection isn't encrypted.

    The socket's cipher for the session is set during the handshake phase. The cipher is used to encrypt and decrypt data transmitted through the socket.

    QSslSocket also provides functions for setting the ordered list of ciphers from which the handshake phase will eventually select the session cipher. This ordered list must be in place before the handshake phase begins.

    This mode decides whether QSslSocket should request a certificate from the peer (i.e., the client requests a certificate from the server, or a server requesting a certificate from the client), and whether it should require that this certificate is valid.

    The default mode is AutoVerifyPeer, which tells QSslSocket to use VerifyPeer for clients and QueryPeer for servers.

    Setting this mode after encryption has started has no effect on the current connection.

    The default SSL configuration of a socket is to use the default ciphers, default CA certificates, no local private key or certificate.

    The SSL configuration also contains fields that can change with time without notice.

    QSslSocket emits this signal after the SSL handshake to indicate that one or more errors have occurred while establishing the identity of the peer.

    The errors are usually an indication that QSslSocket is unable to securely identify the peer. Unless any action is taken, the connection will be dropped after this signal has been emitted.

    If you want to continue connecting despite the errors that have occurred, you must call QSslSocket::ignoreSslErrors() from inside a slot connected to this signal. If you need to access the error list at a later point, you can call sslErrors() (without arguments).

    errors contains one or more errors that prevent QSslSocket from verifying the identity of the peer.

    Note: You cannot use Qt::QueuedConnection when connecting to this signal, or calling QSslSocket::ignoreSslErrors() will have no effect.

    Starts a delayed SSL handshake for a client connection.

    This function can be called when the socket is in the ConnectedState but still in the UnencryptedMode . If it is not yet connected, or if it is already encrypted, this function has no effect.

    Clients that implement STARTTLS functionality often make use of delayed SSL handshakes. Most other clients can avoid calling this function directly by using connectToHostEncrypted() instead, which automatically performs the handshake.

    Starts a delayed SSL handshake for a server connection.

    This function can be called when the socket is in the ConnectedState but still in UnencryptedMode . If it is not connected or it is already encrypted, the function has no effect.

    For server sockets, calling this function is the only way to initiate the SSL handshake. Most servers will call this function immediately upon receiving a connection, or as a result of having received a protocol-specific command to enter SSL mode (e.g, the server may respond to receiving the string "STARTTLS\r\n" by calling this function).

    The most common way to implement an SSL server is to create a subclass of QTcpServer and reimplement QTcpServer::incomingConnection() . The returned socket descriptor is then passed to QSslSocket::setSocketDescriptor() .
