Well not really complete surprise, since the FIPs switch prohibits the use of the "...Managed" libraries in .Net, whereas we should be using the "...CryptoServiceProvider" libraries instead. Of course, I have no control over the Azure deployment but I don't really understand why MS would use the non-FIPs library when there is a FIPs compliant one available. Perhaps the FIPs variants do something nasty with unmanaged libraries... Anyway, solution was to disabled the FIPs checking in the registry and try again!
