.net MVC应用程序Web Config对System.Identity的更改

Question

我有一个带有.net framework 4的asp.net mvc4 Web应用程序。我已经进行了很多研究，但是在下面的代码中找不到如何生成line属性'thumbprint'的值-

我的Web.config代码为-

<system.identityModel>
<identityConfiguration>
 <audienceUris>
  <add value="urn:local-qa"/>
 </audienceUris>
 <issuerNameRegistry type="System.IdentityModel.Tokens.ValidatingIssuerNameRegistry, System.IdentityModel.Tokens.ValidatingIssuerNameRegistry">
   <authority name="urn:ONEDEV.COMPANY.COM/CloudAccessManager/RPSTS">
    <keys>
     <add thumbprint="MIIDIjCCAgqgAwIBAgIQAN85B9wFr"/>
    </keys>
    <validIssuers>
     <add name="urn:ONEDEV.COMPANY.COM/CloudAccessManager/RPSTS"/>
    </validIssuers>
   </authority>
 </issuerNameRegistry>
 <certificateValidation certificateValidationMode="None"/></identityConfiguration>
</system.identityModel>

<system.identityModel.services>
 <federationConfiguration>
  <cookieHandler requireSsl="false"/>
  <wsFederation passiveRedirectEnabled="true" issuer="https://onedev.company.com/CloudAccessManager/RPSTS/WSFed/Default.aspx" realm="urn:local-qa" requireHttps="false"/>
 </federationConfiguration>
</system.identityModel.services>
