Windows Phone 8.1 System.Security.Cryptography doesn't exist

问题

I need to use the System.Security.Cryptography namespace in my Windows Phone 8.1 app - specifically the rsa provider. But there is no such namespace available when i make a Windows Phone app. When I use Siverlight the namespace is there but I cant find it when creating standard Windows Runtime apps. The MSDN documentation says that RSACryptoServiceProvider is available on Windows Phone 8.1, do I need to reference any additonal assemblies to get it working?
