Note that the generated key is stored in a file called mykey, and the encrypted text is stored in the ciphertext file. (We do not show the contents of the ciphertext file, as it is made up of nonprintable binary data, and will differ depending upon the key that is generated.) Once Alice provides the mykey file to Bob over a secure channel, she can then safely send the ciphertext file (or any other files encrypted with the same key) to Bob over an insecure channel. Once Bob receives ciphertext, he can use the AESEncrypter program to decrypt the text as follows: $ java com.learnsecurity.AESEncrypter decrypt mykey < ciphertext Meet Me At Central Park The entire code for the utility is shown here: package com.learnsecurity; import import import import import java.security.*; java.security.spec.*; javax.crypto.*; javax.crypto.spec.*; java.io.*; vb.net pdf library .

By connecting to GtkDialog s response signal, you can wait for a response identifier to be emitted. By using this method, the dialog will not automatically be unreferenced when a response identifier is emitted. The response callback function receives the dialog, the response identifier that was emitted, and the optional data parameter. One of the most important decisions you have to make when designing a dialog is whether it will be modal or nonmodal. As a rule of thumb, if the action needs to be completed before the user can continue working with the application, the dialog should be modal. Examples of this would be message dialogs, dialogs that ask the user a question, and dialogs to open a file. If there is no reason why the user cannot continue working while the dialog is open, you should use a nonmodal dialog. You also need to remember that multiple instances of nonmodal dialogs can be created unless you prevent this programmatically, so dialogs that must have only one instance should be created as modal. itextsharp vb.net pdf to text Reading PDF content with itextsharp dll in VB .

In Listing 5-3, a few pieces of basic information about the user are propagated using GLib s utility functions. A dialog, which is shown in Figure 5-2, allows you to edit each piece of information. In the Dev.bat file, we set up the environment variables for the environment configuration values (some of which still need to be filled in). With one CommonDeploy.bat batch file that runs off environment variables, we can create additional bootstrapper batch files for each target environment. The end of the Dev.bat batch script calls into the CommonDeploy.bat script (shown in listing 17.2) which provides a common bootstrapper file on top of NAnt. pdf sdk vb.net How to use Adobe Acrobat SDK in VB .

A simple GtkDialog widget This information is, of course, not actually changed within the user s system; the new text is simply output to the screen. This example illustrates the fact that, regardless of the complexity of the dialog, the basic principles of how to handle response identifiers are still the only ones that are necessary. The command in listing 17.2 is in a CommonDeploy.bat file, and it calls NAnt using environment variables set up by a previous environment-specific batch file (Dev.bat in our case). The -D command-line switches for NAnt allow us to override properties with the correct deployed values. Because our deployment database will most likely require a different connection string than our local configuration, we need to use NAnt to override this value during deployment. A portion of the deployment.build file is in listing 17.3. convert html to pdf using itextsharp vb.net Export HTML string to PDF file using iTextSharp in ASP. Net
