Figure 7-15. The available patterns A more flexible way to fill shapes is to use gradient brushes, which are brushes based on a QGradient object. A gradient object represents a blend between one or more colors according to a predefined pattern. The available patterns are shown in Figure 7-16. The linear gradient, which is based on the QLinearGradient class, defines a two-dimensional linear gradient. The radial gradient is implemented through QRadialGradient and describes a gradient emanating from a single point where the shade depends on the distance from the point. The conical gradient, QConicalGradient, represents a gradient emanating from a single point where the shade depends on the angle from the point. The different gradients are defined as a spread between two points (except for conical gradients, which start and stop at an angle). The way the gradient is continued outside the range defined by those points is defined by the spread policy, which is set with the setSpread method. The results from the different spread policies are also shown in Figure 7-16. With pad spread (QGradient::PadSpread) the gradient simply stops when the pads have been reached. With repeat spread (QGradient::RepeatSpread) the gradient is repeated. With reflected spread (QGradient::ReflectSpread) the gradient is repeated, but the direction is alternated causing the gradient to be reflected every other time.

A one-time pad is a cipher in which plaintext is XORed with a random stream of bits of the same length as the plaintext A one-time pad is an encryption function in which the plaintext bits are XORed with a key stream A one-time pad is named as such because the key should be used exactly once If an attacker is able to get one bit of plaintext and one bit of corresponding ciphertext, the attacker could simply XOR the two together to recover the key bit! Hence, that key bit should never be used again if Alice and Bob want to securely exchange messages Instead, we d like the key to stay secret even if an attacker obtains many plaintext/ciphertext pairs One-time pads are impractical because using a key that is the same size as the plaintext typically incurs too much overhead.

Caution If you do this, calling an action wrapped by @validate using a GET request will bypass the validation and call the action anyway. You need to make sure this doesn t pose a security risk in your application. You could prevent this by testing whether a GET or a POST is being used in the body of the action. The request method can be determined using request.method.

Note The spread policy does not affect the conical gradients because they define the color of all pixels.

You can customize the way HTML Fill is called by passing any of the arguments accepted by htmlfill.render() as keyword arguments to validate(). For example, to specify a custom error formatter, you can do this: from formencode import htmlfill def custom_formatter(error): return '<span class="custom-message">%s</span><br />\n' % ( htmlfill.html_quote(error) ) Update the submit() action to look like this: @validate(schema=EmailForm(), form='form', post_only=False, on_get=True, auto_error_formatter=custom_formatter) def submit(self): return 'Your email is: %s and the date selected was %r.' % ( self.form_result['email'], self.form_result['date'], ) With this in place, the error messages will be wrapped in <span class="custom-message"> tags. If you run the example, you will notice that the error messages are no longer highlighted in red because there is no style set up for the new error class. You can pass other options to the HTML Fill render() function in the same way via the @validate decorator. The @validate decorator is documented at http://docs.pylonshq.com/modules/decorators.html#module-pylons.decorators.

Why would we want to use such an impractical encryption scheme Claude Shannon proved that one-time pads offer a property called perfect secrecy Perfect secrecy means that under a brute-force attack, every possible decryption is equally likely Consider a scenario in which an attacker gets hold of some ciphertext that was encrypted using a one-time pad The attacker could try a brute-force attack in which she tries decrypting by using every possible combination of key The result of the attacker s decryptions is a list containing one copy of every possible plaintext The brute-force attack yields no information about the plaintext (which is, in general, not true of any imperfect cipher) Hence, since one-time pads offer information theoretic advantages such as perfect secrecy, they would be great to use if we didn t need to have an infinite key.

Figure 7-16. Different gradients and spread policies Listing 7-7 shows how the different gradients are configured. Notice that the linear gradient is defined between two points, forming a direction. The radial gradient is defined by a center point and a radius, while the conical gradient is defined as a center point and a starting angle. The starting angle is specified in degrees, where 0 degrees define the direction pointing right from the center point. The gradients are also assigned colors using the setColorAt method. The colors are set for a value ranging between 0 and 1. These values define a point between the two points for linear gradients, where one point is 0 and the other point is 1. In the same way, 0 defines the starting point, and 1 defines the full specified radius for radial gradients. For conical gradients, 0 specifies the starting angle. The value then increases in the counterclockwise direction until 1 specifies the ending angle which is the same as the starting angle.
