Shouldn't this be in namespace flash { } as well (pp::flash::X509Certificate) to
match the other files within ppapi/cpp/private/flash_* ?

+
+class X509Certificate : public Resource {
+ public:
+  // Creates an is_null() object.
+  X509Certificate();
+  explicit X509Certificate(PP_Resource resource);
+  explicit X509Certificate(const InstanceHandle& instance);
+
+  // Returns true if the required interface is available.
+  static bool IsAvailable();
+
+  // Create a new certificate from a DER-encoded representation. Returns true
+  // if the certificate was successfully created.
+  bool Init(const char* bytes, uint32_t length);
+  // Return the specified field as a |PP_Var|.
+  Var GetField(PP_Flash_X509Certificate_Field field);
+};
