<cryptoClass> Element

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

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.

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>
