+// Internal API backing the chrome.certificateProvider API events.
+// The internal API associates events with replies to these events using request
+// IDs. A custom binding is used to hide these IDs from the public API.
+// Before an event hits the extension, the request ID is removed and instead a
+// callback is added to the event arguments. On the way back, when the extension
+// runs the callback to report its results, the callback magically prepends the
+// request ID to the results and calls the respective internal report function
+// (reportSignature or reportCertificates).
