Contains a cryptography class that has a mapping to a friendly name in the <nameEntry> element.

<configuration>
  <mscorlib>
    <cryptographySettings>
      <cryptoNameMapping>
        <cryptoClasses>
          <cryptoClass>

Syntax

<cryptoClass customClassName="fully qualified type name" />

Attributes and Elements

The following sections describe attributes, child elements, and parent elements.

Attributes

Attribute	Description
`customClassName`	Required attribute. Contains the information for the cryptography class. Use this attribute to provide a short name for your class. You must specify a string that meets the requirements specified in Specifying Fully Qualified Type Names.

Child Elements

None.

Parent Elements

Element	Description
`configuration`	The root element in every configuration file used by the common language runtime and .NET Framework applications.
`cryptoClasses`	Contains a list of cryptography classes that have a mapping to a friendly name in the <nameEntry> element.
`cryptographySettings`	Contains cryptography settings.
`cryptoNameMapping`	Contains mappings of classes to friendly names.
`mscorlib`	Contains the <cryptographySettings> element.

Example

The following example shows how use the <cryptoClass> element to reference a cryptography class and to configure the runtime. You can then pass the string "RSA" to the CryptoConfig.CreateFromName method and use the Create method to return a MyCryptoRSAClass object.

<configuration>  
   <mscorlib>  
      <cryptographySettings>  
         <cryptoNameMapping>  
            <cryptoClasses>  
               <cryptoClass   MyCryptoRSA="MyCryptoRSAClass, MyAssembly  
                  Culture=neutral, PublicKeyToken=a5d015c7d5a0b012,  
                  Version=1.0.0.0"/>  
            </cryptoClasses>  
            <nameEntry name="RSA" class="MyCryptoRSA"/>  
            <nameEntry name="System.Security.Cryptography.AsymmetricAlgorithm"  
                       class="MyCryptoRSA"/>  
         </cryptoNameMapping>  
      </cryptographySettings>  
   </mscorlib>  
</configuration>
