I have had a couple questions regarding encrypting the identity section of the web.config file, so here’s how.

In my example, I use identity impersonate in my web.config file and the physical path is “c:\sourcecode\BigWebApplication\web.config”

<system.web>
    <identity impersonate="true" userName="Alastair" password="password" />
</system.web>

aspnet_regiis –pef system.web/identity c:\sourcecode\BigWebApplication

and to decrypt

aspnet_regiis –pdf system.web/identity c:\sourcecode\BigWebApplication
