详细描述
The QSslCipher class represents an SSL cryptographic cipher.
QSslCipher stores information about one cryptographic cipher. It is most commonly used with QSslSocket, either for configuring which ciphers the socket can use, or for displaying the socket's ciphers to the user.
参见 QSslSocket and QSslKey.
成员函数
QSslCipher::QSslCipher()
Constructs an empty QSslCipher object.
QSslCipher::QSslCipher(const QString &name)
Constructs a QSslCipher object for the cipher determined by name. The constructor accepts only supported ciphers (i.e., the name must identify a cipher in the list of ciphers returned by QSslSocket::supportedCiphers()).
You can call isNull() after construction to check if name correctly identified a supported cipher.
This function was introduced in Qt 5.3.
QSslCipher::QSslCipher(const QString &name, QSsl::SslProtocol protocol)
Constructs a QSslCipher object for the cipher determined by name and protocol. The constructor accepts only supported ciphers (i.e., the name and protocol must identify a cipher in the list of ciphers returned by QSslSocket::supportedCiphers()).
You can call isNull() after construction to check if name and protocol correctly identified a supported cipher.
QSslCipher::QSslCipher(const QSslCipher &other)
Constructs an identical copy of the other cipher.
QSslCipher::~QSslCipher()
Destroys the QSslCipher object.
QString QSslCipher::authenticationMethod() const
Returns the cipher's authentication method as a QString.
QString QSslCipher::encryptionMethod() const
Returns the cipher's encryption method as a QString.
bool QSslCipher::isNull() const
Returns true if this is a null cipher; otherwise returns false.
QString QSslCipher::keyExchangeMethod() const
Returns the cipher's key exchange method as a QString.
QString QSslCipher::name() const
Returns the name of the cipher, or an empty QString if this is a null cipher.
参见 isNull().
QSsl::SslProtocol QSslCipher::protocol() const
Returns the cipher's protocol type, or QSsl::UnknownProtocol if QSslCipher is unable to determine the protocol (protocolString() may contain more information).
参见 protocolString().
QString QSslCipher::protocolString() const
Returns the cipher's protocol as a QString.
参见 protocol().
int QSslCipher::supportedBits() const
Returns the number of bits supported by the cipher.
参见 usedBits().
void QSslCipher::swap(QSslCipher &other)
Swaps this cipher instance with other. This function is very fast and never fails.
This function was introduced in Qt 5.0.
int QSslCipher::usedBits() const
Returns the number of bits used by the cipher.
参见 supportedBits().
bool QSslCipher::operator!=(const QSslCipher &other) const
Returns true if this cipher is not the same as other; otherwise, false is returned.
QSslCipher &QSslCipher::operator=(QSslCipher &&other)
Move-assignment operator.
QSslCipher &QSslCipher::operator=(const QSslCipher &other)
Copies the contents of other into this cipher, making the two ciphers identical.
bool QSslCipher::operator==(const QSslCipher &other) const
Returns true if this cipher is the same as other; otherwise, false is returned.
