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

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
()
销毁 QSslDiffieHellmanParameters 对象。
[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
(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.
另请参阅 isValid () 和 QSslConfiguration .
[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 .
[noexcept]
bool
QSslDiffieHellmanParameters::
isEmpty
() const
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.
[noexcept]
bool
QSslDiffieHellmanParameters::
isValid
() const
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.

[noexcept]
void
QSslDiffieHellmanParameters::
swap
(
QSslDiffieHellmanParameters
&
other
)
交换此 QSslDiffieHellmanParameters with other 。此函数非常快且从不失败。
Copies the contents of other 到此 QSslDiffieHellmanParameters , making the two QSslDiffieHellmanParameters identical.
Returns a reference to this QSslDiffieHellmanParameters .
[noexcept]
QSslDiffieHellmanParameters
&QSslDiffieHellmanParameters::
operator=
(
QSslDiffieHellmanParameters
&&
other
)
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.
[noexcept]
size_t
qHash
(const
QSslDiffieHellmanParameters
&
dhparam
,
size_t
seed
= 0)
Returns an hash value for dhparam ,使用 seed 做计算种子。
[noexcept]
bool
operator!=
(const
QSslDiffieHellmanParameters
&
lhs
, const
QSslDiffieHellmanParameters
&
rhs
)
返回
true
if
lhs
不等于
rhs
;否则返回
false
.
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.

(const
QSslDiffieHellmanParameters
&
lhs
, const
QSslDiffieHellmanParameters
