## Detailed Description

Provider plugin base class.

QCA loads cryptographic provider plugins with QPluginLoader. The QObject obtained when loading the plugin must implement the QCAPlugin interface. This is done by inheriting QCAPlugin, and including Q_INTERFACES(QCAPlugin) in your class declaration.

For example:

class MyPlugin : public QObject, public QCAPlugin
{
Q_OBJECT
Q_INTERFACES(QCAPlugin)
public:
virtual Provider *createProvider() { ... }
};

There is only one function to reimplement, called createProvider(). This function should return a newly allocated Provider instance.

## Constructor & Destructor Documentation
