| You can use the Aspnet_regiis.exe tool to encrypt and decrypt configuration sections. See Encrypting Configuration Information Using Protected Configuration. |
The following configuration file excerpt shows how to declaratively specify protected data providers.
<configProtectedData defaultProvider="RsaProtectedConfigurationProvider">
<providers>
<clear />
<add keyContainerName="NetFrameworkConfigurationKey" cspProviderName="" useMachineContainer="true" useOAEP="false" description="Uses RsaCryptoServiceProvider to encrypt and decrypt" name="RsaProtectedConfigurationProvider" type="System.Configuration.RsaProtectedConfigurationProvider,System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
<add useMachineProtection="true" description="Uses CryptProtectData and CryptUnProtectData Windows APIs to encrypt and decrypt" keyEntropy="" name="DataProtectionConfigurationProvider" type="System.Configuration.DpapiProtectedConfigurationProvider,System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</providers>
</configProtectedData>
The following code example shows how to use the ProtectedConfigurationSection class to programmatically access values in the configProtectedData configuration file section.
