Describes a QSslDiffieHellmanParameters 错误。
| 常量 | 值 | 描述 |
|---|---|---|
QSslDiffieHellmanParameters::NoError
|
0
|
没有出现错误。 |
QSslDiffieHellmanParameters::InvalidInputDataError
|
1
|
The given input data could not be used to construct a QSslDiffieHellmanParameters 对象。 |
QSslDiffieHellmanParameters::UnsafeParametersError
|
2
|
The Diffie-Hellman parameters are unsafe and should not be used. |
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.
Constructs an identical copy of other .
Constructs an empty QSslDiffieHellmanParameters instance.
If an empty QSslDiffieHellmanParameters instance is set on a QSslConfiguration object, Diffie-Hellman negotiation will be disabled.

移动赋值 other 到此 QSslDiffieHellmanParameters 实例。
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.
Copies the contents of other 到此 QSslDiffieHellmanParameters , making the two QSslDiffieHellmanParameters identical.
Returns a reference to this QSslDiffieHellmanParameters .
销毁 QSslDiffieHellmanParameters 对象。

QSslDiffieHellmanParameters
QSslDiffieHellmanParameters::
defaultParameters
()
Returns the default QSslDiffieHellmanParameters used by QSslSocket .
This is currently the 2048-bit MODP group from RFC 3526.
Returns the error that caused the QSslDiffieHellmanParameters object to be invalid.
Returns a human-readable description of the error that caused the QSslDiffieHellmanParameters object to be invalid.
[static]
QSslDiffieHellmanParameters
QSslDiffieHellmanParameters::
fromEncoded
(const
QByteArray
&
encoded
,
QSsl::EncodingFormat
encoding
= QSsl::Pem)
构造 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.

[static]
QSslDiffieHellmanParameters
QSslDiffieHellmanParameters::
fromEncoded
(
QIODevice
*
device
,
QSsl::EncodingFormat
encoding
= QSsl::Pem)
构造 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.
另请参阅 isValid () 和 QSslConfiguration .
返回
true
if this is a an empty
QSslDiffieHellmanParameters
实例。
设置空 QSslDiffieHellmanParameters instance on a QSslSocket -based server will disable Diffie-Hellman key exchange.
返回
true
if this is a valid
QSslDiffieHellmanParameters
；否则 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.

交换此 QSslDiffieHellmanParameters with other 。此函数非常快且从不失败。
Returns an hash value for dhparam ，使用 seed 做计算种子。
该函数在 Qt 5.8 引入。
Writes the set of Diffie-Hellman parameters in dhparam 到 debug 对象 debug 为调试目的。
The Diffie-Hellman parameters will be represented in Base64-encoded DER form.
该函数在 Qt 5.8 引入。
