AES was adopted by NIST in October 2000 as a replacement for DES. A new encryption standard was needed since DES was too easily crackable via brute-force search, and Triple DES was too slow from a performance standpoint for many applications. AES is a replacement for DES and Triple DES that provides security with larger keys and faster execution time. Although AES is a standard that is promoted by NIST, and is a government-endorsed cipher, it was developed using an open process. In 1997, the need for a new standard was announced by NIST, and it invited proposals for a new symmetric block cipher that satisfied its requirements. Fifteen different ciphers were proposed by cryptographers from all over the world, and conferences were held over the course of a three-year period, in which the strengths and weaknesses of the proposed ciphers were debated with regard to security, speed, memory requirements, and other hardware and software implementation considerations. The requirements for AES were more stringent than those for DES because NIST had many more potential applications in mind. For instance, NIST wanted to select an algorithm that would work well on mobile devices that have slower processors and less memory than desktop computers.

To do this, we must first remove the bindings we set up with Visual Studio if we re creating them manually we don t have any need for the ones the designer created. We do this by going back to the (DataBindings) section in the Properties panel, rightclicking on the relevant bound property, and selecting Reset. (If you switched to the event list with the lightning bolt earlier, remember to switch the Properties panel back to property mode.) You need to do this for only the due date and the title the description isn t shown anywhere other than in its text box, which means the default updates are good enough, so we can leave that as is. Then, we can add the highlighted code shown here in the form s constructor directly after the call to InitializeComponent:

public Form1() { InitializeComponent(); titleText.DataBindings.Add("Text", entriesSource, "Title", true, DataSourceUpdateMode.OnPropertyChanged); dueDatePicker.DataBindings.Add("Value", entriesSource, "DueDate", true, DataSourceUpdateMode.OnPropertyChanged); entriesSource.DataSource = entries; } CreateNewItem();

The first three arguments of each of these specify the control property, the data source, and the source property this defines what information the binding connects. The true argument that follows says it s OK for binding to format the data if necessary. These arguments just do the same thing Visual Studio did for us previously. The final argument is the interesting one. We re saying we want the binding to refresh anytime the property changes, rather than the default setting of waiting until either the focus moves or something else means we can t wait any longer (e.g., different data is about to be loaded). With this in place, changes to either the title or the due date will show up immediately in the list view. So we now have some controls that present the data, and in the case of the text boxes and date picker, which will also modify the data. The next job is to make those buttons do something.

To respond to user input in Windows Forms applications, we can just use ordinary C# event handling user interface elements are all represented as objects, and they raise events in the usual way whenever anything interesting happens. As you already saw with the binding source change notifications, Visual Studio can generate the eventhandling code for us.

You can t build a house without a foundation. The same statement holds true for creating mashups. There are two technologies that provide the foundation for all the others: HTTP and the web browser. There are dozens of books written on each of these technologies, and they are fairly well known in general, so I won t go into detail now. But it is always important to know how things work and interrelate, so I will give a broad overview here.

Controls define a default event, usually the event you are most likely to want to handle for the control in question. So we can handle the Click events of the two buttons by double-clicking on them in the designer. Visual Studio will add event handler methods with suitable names and signatures, and will add the code to handle the event in the generated part of the partial class. We simply need to provide the code. The New button handler is pretty straightforward, because we already wrote the code to add a new item:

In August 1999, five finalists were chosen. A proposal called Rijndael, made by two Belgian cryptographers, was chosen to be the AES standard. Rijndael supports key and block sizes of 128, 192, and 256 bits, which is considerably larger than what DES offers. As a result, in applications that need symmetric block encryption, AES achieves better performance and uses less memory than DES or Triple DES. Due to the nature of the selection process that AES went through, the hope is that AES is also more secure than DES. In fact, one of the reasons that Rijndael was chosen is because its mathematical properties were more easily analyzable and provable than other ciphers that were proposed.
