The Cryptography QuickStart demonstrates the following scenarios:

System Requirements

To build and run this QuickStart, you need the following:

  • Microsoft Windows 2000, Windows XP Professional, or Windows Server 2003 operating system
  • Microsoft .NET Framework, version 2.0 or 3.0
  • Microsoft Visual Studio 2005 development system

The QuickStart does not require you to perform any setup procedures prior to building and running the application.

Building the QuickStart

The QuickStart ships as source code, which means that you must compile it before running it. You use Visual Studio to build the QuickStart.

To build the Cryptography QuickStart

  1. Ensure the Enterprise Library Source Code has been installed
  2. Open the Enterprise Library Source Code folder from Windows Explorer, or from the Start Menu shortcut: on the taskbar, click Start, point to All Programs, point to Microsoft patterns and practices, point to Enterprise Library 3.1 – May 2007 and select Enterprise Library 3.1 Source Folder.
  3. Open the QuickStarts folder, then Cryptography, then CS (for C#) or VB (for Visual Basic .NET)
  4. Double-click the CryptographyQuickStart.sln icon.
  5. Visual Studio opens, displaying the solution file. On the menu, click Build.
  6. Click Rebuild Solution. By default, this is a debug build.
  7. Press F5 to run the QuickStart.

QuickStart Configuration

The walkthroughs in the Cryptography QuickStart are shipped with a defined configuration, which is included in the App.config file. This file is located in the same folder as the QuickStart project file.

To change or view these settings, use the Enterprise Library Configuration Console to open the App.config file in the directory that contains the QuickStart project file. The App.config file contains the configuration data.

Each time you build the code, Visual Studio copies the App.config file to the output directory for the project (the same directory where the QuickStart executable is created), and renames it to CryptographyQuickStart.exe.config.

This means that if you want to use the configuration console to change any of the configuration settings, such as the encryption key, and you are planning to rebuild the solution, you must change the settings by opening the App.config file located in the QuickStart source directory. You can change the application configuration by opening the CryptographyQuickStart.exe.config file with the Enterprise Library Configuration Console. However, these changes will be overwritten during the next successful build. The Cryptography QuickStart contains the following default configuration:

  • Hash provider:

    Name: hash provider

    Type: SHA1Managed

    SaltEnabled: True

  • Symmetric provider:

    Name: symprovider

    Type: Microsoft.Practices.EnterpriseLibrary.Security.Cryptography.SymmetricAlgorithmProvider

    algorithmType: RijndaelManaged

    protectedKeyFilename: <installdir>\QuickStarts\Cryptography\SymmetricKeyFile.txt

    The QuickStart method CreateKeys generates a key and saves it to this file.
