QSslConfiguration 用於 Qt 網絡類以中繼有關打開 SSL 連接的信息，並允許應用程序控製該連接的某些特徵。
QSslConfiguration 目前支持的設置包括：
These settings are applied only during the connection handshake. Setting them after the connection has been established has no effect.
The state that QSslConfiguration supports are:
The state can only be obtained once the SSL connection starts, but not necessarily before it's done. Some settings may change during the course of the SSL connection without need to restart it (for instance, the cipher can be changed over time).
State in QSslConfiguration objects cannot be changed.
QSslConfiguration can be used with QSslSocket and the Network Access API.
Note that changing settings in QSslConfiguration is not enough to change the settings in the related SSL connection. You must call setSslConfiguration on a modified QSslConfiguration object to achieve that. The following example illustrates how to change the protocol to TLSv1_0 in a QSslSocket 對象：
QSslConfiguration config = sslSocket.sslConfiguration(); config.setProtocol(QSsl::TlsV1_0); sslSocket.setSslConfiguration(config);

另請參閱 setCaCertificates (), addCaCertificate ()，和 addCaCertificates ().
Returns this connection's current cryptographic cipher suite. This list is used during the handshake phase for choosing a session cipher. The returned list of ciphers is ordered by descending preference. (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 QSslSocket::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 QSslSocket::supportedCiphers().
注意： This is not currently supported in the Schannel backend.

Retrieves the current set of Diffie-Hellman parameters.
If no Diffie-Hellman parameters have been set, the QSslConfiguration object defaults to using the 2048-bit MODP group from RFC 3526.
注意： The default parameters may change in future Qt versions. Please check the documentation of the exact Qt version that you are using in order to know what defaults that version uses.
該函數在 Qt 5.8 引入。
另請參閱 setDiffieHellmanParameters ().
This function returns true if DTLS cookie verification was enabled on a server-side socket.
另請參閱 setDtlsCookieVerificationEnabled ().
Returns this connection's current list of elliptic curves. This list is used during the handshake phase for choosing an elliptic curve (when using an elliptic curve cipher). The returned list of curves is ordered by descending preference (i.e., the first curve in the list is the most preferred one).
By default, the handshake phase can choose any of the curves supported by this system's SSL libraries, which may vary from system to system. The list of curves supported by this system's SSL libraries is returned by QSslSocket::supportedEllipticCurves().
You can restrict the list of curves used for choosing the session cipher for this socket by calling setEllipticCurves () with a subset of the supported ciphers. You can revert to using the entire set by calling setEllipticCurves () with the list returned by QSslSocket::supportedEllipticCurves().
該函數在 Qt 5.5 引入。
另請參閱 setEllipticCurves .
Returns the ephemeral server key used for cipher algorithms with forward secrecy, e.g. DHE-RSA-AES128-SHA.
The ephemeral key is only available when running in client mode, i.e. QSslSocket::SslClientMode . When running in server mode or using a cipher algorithm without forward secrecy a null key is returned. The ephemeral server key will be set before emitting the encrypted() signal.

另請參閱 setLocalCertificate ().
Returns the certificate chain to be presented to the peer during the SSL handshake process.
該函數在 Qt 5.1 引入。
另請參閱 setLocalCertificateChain () 和 localCertificate ().
This function returns the protocol negotiated with the server if the Next Protocol Negotiation (NPN) or Application-Layer Protocol Negotiation (ALPN) TLS extension was enabled. In order for the NPN/ALPN extension to be enabled, setAllowedNextProtocols () needs to be called explicitly before connecting to the server.
If no protocol could be negotiated or the extension was not enabled, this function returns a QByteArray which is null.
該函數在 Qt 5.3 引入。
另請參閱 setAllowedNextProtocols () 和 nextProtocolNegotiationStatus ().
This function returns the status of the Next Protocol Negotiation (NPN) or Application-Layer Protocol Negotiation (ALPN). If the feature has not been enabled through setAllowedNextProtocols (), this function returns NextProtocolNegotiationNone . The status will be set before emitting the encrypted() signal.

另請參閱 setAllowedNextProtocols (), allowedNextProtocols (), nextNegotiatedProtocol ()，和 QSslConfiguration::NextProtocolNegotiationStatus .
Returns true if OCSP stapling was enabled by setOCSPStaplingEnabled(), otherwise false (which is the default value).
該函數在 Qt 5.13 引入。
另請參閱 setOcspStaplingEnabled ().
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 QSslSocket::sslErrors() signal, QNetworkReply::sslErrors () signal, or the QSslSocket::encrypted () 信號。
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.
若想要校驗對等方完整證書鏈，使用 peerCertificateChain () 以一次獲取它們所有。
另請參閱 peerCertificateChain (), QSslSocket::sslErrors (), QSslSocket::ignoreSslErrors (), QNetworkReply::sslErrors ()，和 QNetworkReply::ignoreSslErrors ().
Returns the peer's chain of digital certificates, starting with the peer's immediate certificate and ending with the CA's certificate.
Peer certificates are checked automatically during the handshake phase. This function is normally used to fetch certificates for display, or for performing connection diagnostics. Certificates contain information about the peer and the certificate issuers, including host name, issuer names, and issuer public keys.
Because the peer certificate is set during the handshake phase, it is safe to access the peer certificate from a slot connected to the QSslSocket::sslErrors() signal, QNetworkReply::sslErrors () signal, or the QSslSocket::encrypted () 信號。
If an empty list 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.
若隻想獲得對等方即時證書，使用 peerCertificate ().
另請參閱 peerCertificate (), QSslSocket::sslErrors (), QSslSocket::ignoreSslErrors (), QNetworkReply::sslErrors ()，和 QNetworkReply::ignoreSslErrors ().
Returns the maximum number of certificates in the peer's certificate chain to be checked during the SSL handshake phase, or 0 (the default) if no maximum depth has been set, indicating that the whole certificate chain should be checked.
The certificates are checked in issuing order, starting with the peer's own certificate, then its issuer's certificate, and so on.
另請參閱 setPeerVerifyDepth () 和 peerVerifyMode ().
Returns the verify mode. 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, QueryPeer for servers.

另請參閱 setPrivateKey () 和 localCertificate ().
Returns the protocol setting for this SSL configuration.
另請參閱 setProtocol ().
返迴套接字的加密 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.
The SSL infrastructure 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.
另請參閱 ciphers (), setCiphers ()，和 QSslSocket::supportedCiphers ().
Returns the socket's SSL/TLS protocol or UnknownProtocol if the connection isn't encrypted. The socket's protocol for the session is set during the handshake phase.
該函數在 Qt 5.4 引入。
另請參閱 protocol () 和 setProtocol ().
若 QSsl::SslOptionDisableSessionPersistence was turned off, this function returns the session ticket used in the SSL handshake in ASN.1 format, suitable to e.g. be persisted to disk. If no session ticket was used or QSsl::SslOptionDisableSessionPersistence was not turned off, this function returns an empty QByteArray .
注意： When persisting the session ticket to disk or similar, be careful not to expose the session to a potential attacker, as knowledge of the session allows for eavesdropping on data encrypted with the session parameters.
該函數在 Qt 5.2 引入。
另請參閱 setSessionTicket (), QSsl::SslOptionDisableSessionPersistence , setSslOption ()，和 QSslSocket::newSessionTicketReceived ().
若 QSsl::SslOptionDisableSessionPersistence was turned off, this function returns the session ticket life time hint sent by the server (which might be 0). If the server did not send a session ticket (e.g. when resuming a session or when the server does not support it) or QSsl::SslOptionDisableSessionPersistence was not turned off, this function returns -1.
該函數在 Qt 5.2 引入。
另請參閱 sessionTicket (), QSsl::SslOptionDisableSessionPersistence , setSslOption ()，和 QSslSocket::newSessionTicketReceived ().
This function sets the allowed protocols to be negotiated with the server through the Next Protocol Negotiation (NPN) or Application-Layer Protocol Negotiation (ALPN) TLS extension; each element in protocols must define one allowed protocol. The function must be called explicitly before connecting to send the NPN/ALPN extension in the SSL handshake. Whether or not the negotiation succeeded can be queried through nextProtocolNegotiationStatus ().
該函數在 Qt 5.3 引入。
另請參閱 nextNegotiatedProtocol (), nextProtocolNegotiationStatus (), allowedNextProtocols (), QSslConfiguration::NextProtocolSpdy3_0 ，和 QSslConfiguration::NextProtocolHttp1_1 .

另請參閱 backendConfiguration () 和 setBackendConfigurationOption ().
設置選項 name in the backend-specific configuration to value .
Options supported by the OpenSSL (>= 1.0.2) backend are available in the supported configuration file commands documentation. The expected type for the value parameter is a QByteArray for all options. The examples show how to use some of the options.
注意： The backend-specific configuration will be applied after the general configuration. Using the backend-specific configuration to set a general configuration option again will overwrite the general configuration option.
該函數在 Qt 5.11 引入。
另請參閱 backendConfiguration () 和 setBackendConfiguration ().
Sets this socket's CA certificate database to be certificates . The certificate database must be set prior to the SSL handshake. The CA certificate database is used by the socket during the handshake phase to validate the peer's certificate.

Sets the certificate to be presented to the peer during SSL handshake to be certificate .
Setting the certificate once the connection has been established has no effect.
A certificate is the means of identification used in the SSL process. The local certificate is used by the remote end to verify the local user's identity against its list of Certification Authorities. In most cases, such as in HTTP web browsing, only servers identify to the clients, so the client does not send a certificate.
另請參閱 localCertificate ().
Sets the certificate chain to be presented to the peer during the SSL handshake to be localChain .
Setting the certificate chain once the connection has been established has no effect.
A certificate is the means of identification used in the SSL process. The local certificate is used by the remote end to verify the local user's identity against its list of Certification Authorities. In most cases, such as in HTTP web browsing, only servers identify to the clients, so the client does not send a certificate.
不像 QSslConfiguration::setLocalCertificate () this method allows you to specify any intermediate certificates required in order to validate your certificate. The first item in the list must be the leaf certificate.
該函數在 Qt 5.1 引入。
另請參閱 localCertificateChain ().
若 enabled is true, client QSslSocket will send a certificate status request to its peer when initiating a handshake. During the handshake QSslSocket will verify the server's response. This value must be set before the handshake starts.
該函數在 Qt 5.13 引入。
另請參閱 ocspStaplingEnabled ().
Sets the maximum number of certificates in the peer's certificate chain to be checked during the SSL handshake phase, to depth . Setting a depth of 0 means that no maximum depth is set, indicating that the whole certificate chain should be checked.
The certificates are checked in issuing order, starting with the peer's own certificate, then its issuer's certificate, and so on.
另請參閱 peerVerifyDepth () 和 setPeerVerifyMode ().
Sets the verify mode to mode . 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, QueryPeer for servers.
另請參閱 peerVerifyMode ().
Sets the identity hint for a preshared key authentication to hint . This will affect the next initiated handshake; calling this function on an already-encrypted socket will not affect the socket's identity hint.
The identity hint is used in QSslSocket::SslServerMode only!
該函數在 Qt 5.8 引入。
另請參閱 preSharedKeyIdentityHint ().
Sets the connection's private key to key . The private key and the local certificate are used by clients and servers that must prove their identity to SSL peers.
Both the key and the local certificate are required if you are creating an SSL server socket. If you are creating an SSL client socket, the key and local certificate are required if your client must identify itself to an SSL server.
另請參閱 privateKey () 和 setLocalCertificate ().
Sets the protocol setting for this configuration to be protocol .
Setting the protocol once the connection has already been established has no effect.
另請參閱 protocol ().
