Detailed Description

The QSslDiffieHellmanParameters class provides an interface for Diffie-Hellman parameters for servers.

Since: 5.8

\reentrant

\inmodule QtNetwork

QSslDiffieHellmanParameters provides an interface for setting Diffie-Hellman parameters to servers based on QSslSocket.

Constructor & Destructor Documentation

◆ QSslDiffieHellmanParameters() [1/3]

QSslDiffieHellmanParameters::QSslDiffieHellmanParameters ( )

Constructs an empty QSslDiffieHellmanParameters instance.

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

See also: isValid(); QSslConfiguration

Definition at line 101 of file qssldiffiehellmanparameters.cpp.

Here is the call graph for this function:

◆ QSslDiffieHellmanParameters() [2/3]

QSslDiffieHellmanParameters::QSslDiffieHellmanParameters ( const QSslDiffieHellmanParameters & other )

Constructs an identical copy of other.

Definition at line 160 of file qssldiffiehellmanparameters.cpp.

Here is the call graph for this function:

◆ QSslDiffieHellmanParameters() [3/3]

QSslDiffieHellmanParameters::QSslDiffieHellmanParameters ( QSslDiffieHellmanParameters && other )

inlinenoexcept

Move-constructs from other.

Note: 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.

Definition at line 79 of file qssldiffiehellmanparameters.h.

Here is the call graph for this function:

◆ ~QSslDiffieHellmanParameters()

QSslDiffieHellmanParameters::~QSslDiffieHellmanParameters ( )

Destroys the QSslDiffieHellmanParameters object.

Definition at line 179 of file qssldiffiehellmanparameters.cpp.

Member Function Documentation

◆ defaultParameters()

QSslDiffieHellmanParameters QSslDiffieHellmanParameters::defaultParameters ( )

static

Returns the default QSslDiffieHellmanParameters used by QSslSocket.

This is currently the 1024-bit MODP group from RFC 2459, also known as the Second Oakley Group.

Definition at line 84 of file qssldiffiehellmanparameters.cpp.

Here is the call graph for this function:

Here is the caller graph for this function:

◆ error()

QSslDiffieHellmanParameters::Error QSslDiffieHellmanParameters::error ( ) const

noexcept

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

Definition at line 260 of file qssldiffiehellmanparameters.cpp.

◆ errorString()

QString QSslDiffieHellmanParameters::errorString ( ) const

noexcept

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

Definition at line 269 of file qssldiffiehellmanparameters.cpp.

Here is the call graph for this function:

◆ fromEncoded() [1/2]

QSslDiffieHellmanParameters QSslDiffieHellmanParameters::fromEncoded	(	const QByteArray &	encoded,
		QSsl::EncodingFormat	encoding = `QSsl::Pem`
	)

static

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

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

See also: isValid(); QSslConfiguration

Definition at line 118 of file qssldiffiehellmanparameters.cpp.

◆ fromEncoded() [2/2]

QSslDiffieHellmanParameters QSslDiffieHellmanParameters::fromEncoded	(	QIODevice *	device,
		QSsl::EncodingFormat	encoding = `QSsl::Pem`
	)

static

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

Use the 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.

See also: isValid(); QSslConfiguration

Definition at line 149 of file qssldiffiehellmanparameters.cpp.

◆ isEmpty()

bool QSslDiffieHellmanParameters::isEmpty ( ) const

noexcept

Returns true if this is a an empty QSslDiffieHellmanParameters instance.

Setting an empty QSslDiffieHellmanParameters instance on a QSslSocket-based server will disable Diffie-Hellman key exchange.

Definition at line 220 of file qssldiffiehellmanparameters.cpp.

Here is the call graph for this function:

◆ isValid()

bool QSslDiffieHellmanParameters::isValid ( ) const

noexcept

Returns true if this is a valid QSslDiffieHellmanParameters; otherwise false.

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

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

See also: error()

Definition at line 236 of file qssldiffiehellmanparameters.cpp.

◆ operator=() [1/2]

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

Copies the contents of other into this QSslDiffieHellmanParameters, making the two QSslDiffieHellmanParameters identical.

Returns a reference to this QSslDiffieHellmanParameters.

Definition at line 191 of file qssldiffiehellmanparameters.cpp.

◆ operator=() [2/2]

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

inlinenoexcept

Move-assigns other to this QSslDiffieHellmanParameters instance.

Note: 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.

Definition at line 83 of file qssldiffiehellmanparameters.h.

Here is the call graph for this function:

◆ swap()

void QSslDiffieHellmanParameters::swap ( QSslDiffieHellmanParameters & other )

inlinenoexcept

Swaps this QSslDiffieHellmanParameters with other. This function is very fast and never fails.
