def submit(self): # Code to perform some action based on the form data # ... h.redirect_to(controller='formtest', action='result') def result(self): return 'Your data was successfully submitted.' This code requires the use of the redirect_to() helper. Add the following import to the project s lib/helpers.py file: from pylons.controllers.util import redirect_to Then in the controller, import the helpers module by adding this line at the top: import formdemo.lib.helpers as h Now you can test the controller. In this case, once the form is submitted, the data is saved, and an HTTP redirect occurs so that the browser redirects to http://localhost:5000/hello/result. If the user then refreshes the page, it simply redisplays the message rather than reperforming the action. One issue with this approach is that if you want to display some of the submitted data, you will need to load it again in the result() action because the request that calls that action doesn t contain any of the submitted data. In 8, I ll cover how these sorts of messages can be displayed by storing information in a session store.

A brute-force attacker who was capable of trying all 256 key combinations would now have to try many more combinations! The entire Triple DES key is 192 bits including the parity bits Alternatively, you could use only two different keys, and set k1 = k3 to get 112 bits of security The key would be 128 bits with the parity bits While Triple DES provides more security than DES, it can be up to three times slower than DES from a performance standpoint, since two DES encryptions and one DES decryption needs to be done in one Triple DES encryption Using Triple DES is favorable to using DES because Triple DES allows the use of a larger key.

Forms can also be created with Pylons built-in helpers. You ve already seen the helpers in 3 and learned about how they escape data to avoid security problems in 5; in this section, you ll learn how to use the HTML helpers to create forms.

We may be afraid that if we just use 64-bit DES alone, an attacker that gets ahold of just one plaintext/ciphertext pair could just try decrypting the ciphertext with all 256 keys to determine the key..

be stored on the X server (handing the screen), meaning less communication between the application and the X server.

Note The WebHelpers package from which the Pylons helpers are imported changed significantly in version 0.6. All the old helpers from Rails were deprecated in favor of the new-style literal approach documented in 5. All the JavaScript integration with Prototype and Script.aculo.us was also removed because the majority of developers preferred to use their own JavaScript framework. You ll learn more about Pylons integration with JavaScript frameworks in 15.

Let s update the form you ve been working on to use some of the HTML form helpers. Change the simpleform.html file to look like this: <%inherit file="/base.html" /> <h1>Enter Your E-mail Address</h1> ${h.form(h.url_for(controller='formtest', action='submit'), method='get')} Email Address: ${h.text('email')} ${h.submit('submit', 'Submit')} ${h.end_form()} You can see that you are using the form(), url_for(), text(), and submit() helpers. The url_for() helper actually comes from Routes, but the other helpers come from the webhelpers.html.tags module. You ll need to add all these helpers to your sample project s lib/helpers.py file too in order for this example to work:

Listing 7-2. Creating a pixmap and a painter before setting up a pen and a brush QPixmap pixmap( 200, 100 ); QPainter painter( &pixmap ); painter.setPen( Qt::red ); painter.setBrush( Qt::yellow ); ... Listing 7-2 sets the pen and brush to Qt s standard colors a red pen and a yellow brush in this case. It is possible to create colors from the red, green, and blue components through the constructor of the QColor class. You can use the static methods QColor::fromHsv and QColor::fromCmyk to create a color from hue, saturation, and value; or cyan, magenta, yellow, and black. Qt also supports an alpha channel, controlling the opacity of each pixel. (You ll experiment with this later in the chapter.) If you want to clear the pen and brush setting, you can use the setPen(Qt::noPen) and setBrush(Qt::noBrush) calls. The pen is used to draw the outlines of shapes, while the brush is used to fill them. Hence, you can draw the outlines without a brush and fill the shapes without a pen.
