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.

QSslCipher:: QSslCipher ()

构造空的 QSslCipher 对象。

QSslCipher:: QSslCipher (const QString & name )

构造 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()).

可以调用 isNull () after construction to check if name correctly identified a supported cipher.

该函数在 Qt 5.3 引入。

QSslCipher:: QSslCipher (const QString & name , QSsl::SslProtocol protocol )

构造 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()).

可以调用 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 ()

销毁 QSslCipher 对象。

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

返回 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.

另请参阅 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).

另请参阅 protocolString ().

QString QSslCipher:: protocolString () const

Returns the cipher's protocol as a QString .

另请参阅 protocol ().

int QSslCipher:: supportedBits () const

Returns the number of bits supported by the cipher.

另请参阅 usedBits ().

void QSslCipher:: swap ( QSslCipher & other )

Swaps this cipher instance with other 。此函数非常快且从不失败。

该函数在 Qt 5.0 引入。

int QSslCipher:: usedBits () const

Returns the number of bits used by the cipher.

另请参阅 supportedBits ().

bool QSslCipher:: operator!= (const QSslCipher & other ) const

返回 true if this cipher is not the same as other ; otherwise, false is returned.

QSslCipher &QSslCipher:: operator= ( QSslCipher && other )

移动赋值运算符。

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

返回 true if this cipher is the same as other ; otherwise, false is returned.
