enum QSslDiffieHellmanParameters:: Error

Describes a QSslDiffieHellmanParameters 錯誤。

常量	值	描述
QSslDiffieHellmanParameters::NoError	0	沒有齣現錯誤。
QSslDiffieHellmanParameters::InvalidInputDataError	1	The given input data could not be used to construct a QSslDiffieHellmanParameters 對象。
QSslDiffieHellmanParameters::UnsafeParametersError	2	The Diffie-Hellman parameters are unsafe and should not be used.

QSslDiffieHellmanParameters:: QSslDiffieHellmanParameters ()

Constructs an empty QSslDiffieHellmanParameters instance.

If an empty QSslDiffieHellmanParameters instance is set on a QSslConfiguration object, Diffie-Hellman negotiation will be disabled.

另請參閱 isValid () 和 QSslConfiguration .

QSslDiffieHellmanParameters:: QSslDiffieHellmanParameters (const QSslDiffieHellmanParameters & other )

Constructs an identical copy of other .

[noexcept] QSslDiffieHellmanParameters:: QSslDiffieHellmanParameters ( QSslDiffieHellmanParameters && other )

Move-constructs from other .

注意： The moved-from object other is placed in a partially-formed state, in which the only valid operations are destruction and assignment of a new value.

[noexcept] QSslDiffieHellmanParameters:: ~QSslDiffieHellmanParameters ()

銷毀 QSslDiffieHellmanParameters 對象。

[static] QSslDiffieHellmanParameters QSslDiffieHellmanParameters:: defaultParameters ()

Returns the default QSslDiffieHellmanParameters used by QSslSocket .

This is currently the 2048-bit MODP group from RFC 3526.

[noexcept] QSslDiffieHellmanParameters::Error QSslDiffieHellmanParameters:: error () const

Returns the error that caused the QSslDiffieHellmanParameters object to be invalid.

[noexcept] QString QSslDiffieHellmanParameters:: errorString () const

Returns a human-readable description of the error that caused the QSslDiffieHellmanParameters object to be invalid.

[static] QSslDiffieHellmanParameters QSslDiffieHellmanParameters:: fromEncoded ( QIODevice * device , QSsl::EncodingFormat encoding = QSsl::Pem)

構造 QSslDiffieHellmanParameters object by reading from device in either PEM or DER form as specified by encoding .

使用 isValid () method on the returned object to check whether the Diffie-Hellman parameters were valid and loaded correctly.

In particular, if device is nullptr or not open for reading, an invalid object will be returned.

另請參閱 isValid () 和 QSslConfiguration .

[static] QSslDiffieHellmanParameters QSslDiffieHellmanParameters:: fromEncoded (const QByteArray & encoded , QSsl::EncodingFormat encoding = QSsl::Pem)

構造 QSslDiffieHellmanParameters object using the byte array encoded in either PEM or DER form as specified by encoding .

使用 isValid () method on the returned object to check whether the Diffie-Hellman parameters were valid and loaded correctly.

另請參閱 isValid () 和 QSslConfiguration .

[noexcept] bool QSslDiffieHellmanParameters:: isEmpty () const

返迴 true if this is a an empty QSslDiffieHellmanParameters 實例。

設置空 QSslDiffieHellmanParameters instance on a QSslSocket -based server will disable Diffie-Hellman key exchange.

[noexcept] bool QSslDiffieHellmanParameters:: isValid () const

返迴 true if this is a valid QSslDiffieHellmanParameters ；否則 false。

This method should be used after constructing a QSslDiffieHellmanParameters object to determine its validity.

若 QSslDiffieHellmanParameters object is not valid, you can use the error () method to determine what error prevented the object from being constructed.

另請參閱 error ().

[noexcept] void QSslDiffieHellmanParameters:: swap ( QSslDiffieHellmanParameters & other )

交換此 QSslDiffieHellmanParameters with other 。此操作很快且從不失敗。

[noexcept] QSslDiffieHellmanParameters &QSslDiffieHellmanParameters:: operator= ( QSslDiffieHellmanParameters && other )

移動賦值 other 到此 QSslDiffieHellmanParameters 實例。

注意： The moved-from object other is placed in a partially-formed state, in which the only valid operations are destruction and assignment of a new value.

QSslDiffieHellmanParameters &QSslDiffieHellmanParameters:: operator= (const QSslDiffieHellmanParameters & other )

Copies the contents of other 到此 QSslDiffieHellmanParameters , making the two QSslDiffieHellmanParameters identical.

Returns a reference to this QSslDiffieHellmanParameters .

[noexcept] size_t qHash (const QSslDiffieHellmanParameters & key , size_t seed = 0)

返迴哈希值為 key ，使用 seed 做計算種子。

[noexcept] bool operator!= (const QSslDiffieHellmanParameters & lhs , const QSslDiffieHellmanParameters & rhs )

返迴 true if lhs 不等於 rhs ；否則返迴 false .

QDebug operator<< ( QDebug debug , const QSslDiffieHellmanParameters & dhparam )

Writes the set of Diffie-Hellman parameters in dhparam 到 debug 對象 debug 為調試目的。

The Diffie-Hellman parameters will be represented in Base64-encoded DER form.

另請參閱 調試技術 .

[noexcept] bool operator== (const QSslDiffieHellmanParameters & lhs , const QSslDiffieHellmanParameters & rhs )

返迴 true if lhs 等於 rhs ；否則返迴 false .
