             * Reading Certificates from the Mac Keychain
             * ==========================================
             *
             * Reading the private key from the keychain is a new feature introduced with
             * AppleTls on XamMac and iOS. On Desktop Mono, this new feature has several
             * known issues and it also did not received any testing yet. We go back to the old
             * way of doing things, which is to explicitly provide an X509Certificate2 with a
             * private key.
             *
             * Keychain Dialog Popups
             * ======================
             *
             * When using Xamarin.Mac or Xamarin.iOS, we try to search the keychain
             * for the certificate and private key.
             *
             * On Xamarin.iOS, this is easy because each app has its own keychain.
             *
             * On Xamarin.Mac, the .app package needs to be trusted via code-sign
             * to get permission to access the user's keychain. [FIXME: I still have to
             * research how to actually do that.] Without this, you will get a popup
             * message each time, asking you whether you want to allow the app to access
             * the keychain, but you can make these go away by selecting "Trust always".
             *
             * On Desktop Mono, this is problematic because selecting "Trust always"
             * give the 'mono' binary (and thus everything you'll ever run with Mono)
             * permission to retrieve the private key from the keychain.
             *
             * This code would also trigger constant keychain popup messages,
             * which could only be suppressed by granting full trust. It also makes it
             * impossible to run Mono in headless mode.
             *
             * SecIdentityCreate
             * =================
             *
             * To avoid these problems, we are currently using an undocumented API
             * called SecIdentityRef() to avoid using the Mac keychain whenever a
             * X509Certificate2 with a private key is used.
             *
             * On iOS and XamMac, you can still provide the X509Certificate without
             * a private key - in this case, a keychain search will be performed (and you
             * may get a popup message on XamMac).
