<oidEntry> Element

Maps an ASN.1 object identifier (OID) to a friendly name.

<configuration>
   <mscorlib>
      <cryptographySettings>
         <oidMap>
            <oidEntry>

<oidEntry OID="object identifier number" name="friendly name" />

Required Attributes

Attribute Description
OID Specifies the ASN.1 OID corresponding to the algorithm implemented by your class.
name Specifies the value for the name attribute in the <nameEntry> tag.

Remarks

ASN.1 object identifiers identify algorithms in some cryptographic formats. Map object identifiers to friendly names for the algorithms you want to identify. For more information about object identifiers, see the MSDN Library.

Example

The following example shows how to use the <oidEntry> element to map an object identifier for the RIPEMD-160 hash algorithm to an implementation of that hash algorithm.

<configuration>
   <mscorlib>
      <cryptographySettings>
         <cryptoNameMapping>
            <cryptoClasses>
               <cryptoClass   MyCrypto="MyCryptoClass, MyAssembly
                  Culture=neutral, PublicKeyToken=a5d015c7d5a0b012,
                  Version=1.0.0.0"/>
            </cryptoClasses>
            <nameEntry name="RIPEMD-160" class="MyCrypto"/>
         </cryptoNameMapping>
         <oidMap>
            <oidEntry OID="1.3.36.3.2.1"   name="MyCryptoClass"/>
         </oidMap>
      </cryptographySettings>
   </mscorlib>
</configuration>
