>+        Broadly:
>+        - Fix leaks by switching from using raw pointers to using
>+          std::unique_ptr<>.
>+        - Introduce PlatformRSAKeyContainer type to handle different
>+          std::unique_ptr<> on each platform.
>+        - Get rid of custom CryptoKeyRSA destructors since the
>+          std::unique_ptr<> handles that with a Deleter.
>+        - Initialize stack variables to nullptr.
