详细描述

This class is part of the Qt KNX module and currently available as a Technology Preview, and therefore the API and functionality provided by the class may be subject to change at any time without prior notice.

注意： To use this class OpenSSL must be supported on your target system.

This frame will be sent by the KNXnet/IP secure server to the KNXnet/IP secure client control endpoint in response to a received secure session request frame.

The common way to create a session response frame is:

auto serverPublicKey = ... // create the public key
auto auth = ... // create the full 128 bit CCM-MAC
auto netIpFrame = QKnxNetIpSessionResponseProxy::secureBuilder()
    .setSecureSessionId(0x1976)
    .setPublicKey(serverPublicKey)
    .create();

SecureBuilder:: SecureBuilder (const SecureBuilder & other )

构造副本为 other .

SecureBuilder:: SecureBuilder ()

Creates a new empty session response builder object.

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

赋值指定 other 到此对象。

SecureBuilder:: ~SecureBuilder ()

销毁对象并释放任何分配资源。

QKnxNetIpFrame SecureBuilder:: create (const QByteArray & devicePassword , const QKnxByteArray & clientPublicKey ) const

Creates and returns a KNXnet/IP session response frame.

The function computes the AES128 CCM message authentication code (MAC) with the given device password devicePassword and the Curve25519 client public key clientPublicKey and appends it to the newly created frame.

注意： The returned frame may be invalid depending on the values used during setup.

另请参阅 isValid ().

SecureBuilder &SecureBuilder:: setPublicKey (const QKnxByteArray & serverPublicKey )

Sets the public key of the KNXnet/IP session response frame to serverPublicKey and returns a reference to the builder. The public key needs to be generated using the Curve25519 algorithm and has a fixed size of 32 字节。

SecureBuilder &SecureBuilder:: setSecureSessionId ( quint16 sessionId )

Sets the secure session ID of the KNXnet/IP session response frame to sessionId and returns a reference to the builder.
