Reading machinekey at runtime

Hi,

I've a asp.net 4.0 web application and I want to read the machine key at runtime

<machineKey validationKey="AutoGenerate,IsolateApps"decryptionKey="AutoGenerate,IsolateApps"validation="HMACSHA256"decryption="Auto" />

Is there a way that I can read this key in C# at runtime?

Best regards,

Mark
