Because of this, Pylons encourages you to do a lot of the work of generating forms yourself, but it does provide four sets of tools to make form handling as painless as possible: Form helpers to generate the HTML for common field types Validators to validate form data and convert between HTML and Python representations of particular data types HTML Fill to take an HTML form and automatically populate it with values and error messages for redisplaying the form data The @validate decorator to automate the process of validating a form and redisplaying it if it contains invalid data These four tools can help make handling forms much simpler without in any way constraining your creativity as a developer Pylons does support an alternative approach with a tool, called ToscaWidgets, although it won t be covered in this chapter.

Encryption can help us achieve confidentiality, among other security goals. In this section, we start exploring cryptographic primitives for encryption. In particular, we will start with studying block ciphers, in which, say, blocks of 64, 128, or 256 bits are encrypted at one time. Many encryption algorithms have been developed over time, and we examine a few of them here. We start by looking at the Data Encryption Standard (DES) and Triple DES algorithms. We will also cover the Advanced Encryption Standard (AES) algorithm selected by NSA in 2000 to deal with the inevitable obsolescence of DES. In addition to DES, Triple DES, and AES block ciphers, we also discuss RC4, a stream cipher, in Section 12.2.2.

Listing 6-25. Changes to the CircleBar class class QDESIGNER_WIDGET_EXPORT CircleBar : public QWidget { Q_OBJECT public: CircleBar( QWidget *parent = 0 ); CircleBar( int value = 0, QWidget *parent = 0 ); int value() const; int heightForWidth( int ) const; QSize sizeHint() const; public slots: void setValue( int ); signals: void valueChanged( int ); protected: void paintEvent( QPaintEvent* ); void wheelEvent( QWheelEvent* ); private: int m_value; }; Now you can start looking at the actual plugin in Listing 6-26. The plugin class is simply an implementation of the interface defined by the QDesignerCustomWidgetInterface class. All methods must be implemented, and the task of each method is strictly defined. The plugin class for the CircleBar widget is called CircleBarPlugin. This is a common way to name widget plugin classes. Listing 6-26. The plugin class #ifndef CIRCLEBARPLUGIN_H #define CIRCLEBARPLUGIN_H #include <QDesignerCustomWidgetInterface> class QExtensionManager; class CircleBarPlugin : public QObject, public QDesignerCustomWidgetInterface { Q_OBJECT Q_INTERFACES(QDesignerCustomWidgetInterface)

ToscaWidgets is a full form framework developed from the original widgets code in TurboGears that automates every aspect of form handling ToscaWidgets is still officially in prerelease, but if you are interested in its approach, you should visit http://toscawidgetsorg to find out more The majority of developers prefer the flexibility of the approach you ll use in this chapter..

public: CircleBarPlugin( QObject *parent = 0 ); bool isContainer() const; bool isInitialized() const; QIcon icon() const; QString domXml() const; QString group() const; QString includeFile() const; QString name() const; QString toolTip() const; QString whatsThis() const; QWidget *createWidget( QWidget *parent ); void initialize( QDesignerFormEditorInterface *core ); private: bool m_initialized; }; #endif /* CIRCLEBARPLUGIN_H */ First, widgets must handle an initialized flag, which is done through the constructor and the isInitialized() and initialize(QDesignerFormEditorInterface*) methods. The methods are shown in Listing 6-27. You can see that the implementation is pretty straightforward and can be copied and pasted between all widget plugin classes. Listing 6-27. Handing initialization CircleBarPlugin::CircleBarPlugin( QObject *parent ) { m_initialized = false; } bool CircleBarPlugin::isInitialized() const { return m_initialized; } void CircleBarPlugin::initialize( QDesignerFormEditorInterface *core ) { if( m_initialized ) return; m_initialized = true; }

While we present a few representative symmetric encryption algorithms here, there are many more that have been developed. The International Data Encryption Algorithm (IDEA), A5 (an encryption algorithm used as part of the GSM cell phone standard), Blowfish, and Skipjack are examples of other encryption algorithms. If you re interested in learning more about encryption algorithms, you should read Practical Cryptography, by Niels Ferguson and Bruce Schneier, or Applied Cryptography: Protocols, Algorithms, and Source Code in C, by Bruce Schneier. Both books catalog many more algorithms than we discuss in this book. Each of these algorithms use different key lengths. They also have different security properties, and some of them are ideal for different applications. Using DES, Triple DES, AES, and RC4 as examples, we provide you some idea of how symmetric encryption algorithms work, and what the trade-offs between them are.

When a user submits a form on a web site, the data is submitted to the URL specified in the action attribute of the <form> tag. The data can be submitted either via HTTP GET or POST as specified by the method attribute of the <form> tag. If your form doesn t specify an action, then it s submitted to the current URL, but generally you ll want to specify an action attribute.
