This doesn't necessarily call DecryptorReady. It calls a callback. This could
probably have a generic name.

[jrummell, 2014/08/08 20:58:28]

Done.

+  // verifier must be called first since |done_cb| call will trigger it as well.

s/trigger/invoke/?
or call?

[jrummell, 2014/08/08 20:58:28]

Done.

naming: This doesn't really verify that the callback happened.

Done.
