Did you try using the IPC_STRUCT_TRAITS_BEGIN/END stuff like this?
https://code.google.com/p/chromium/codesearch#chromium/src/ppapi/proxy/ppapi_...
I'm not certain it works with a fixed array like key_id, but *if* it does, it
would be simpler. (I'm guessing you tried that and it didn't work, though, in
which case ParamTraits is appropriate).

I did try it, but got compile errors with ParamTraits<uint8_t[512]>. Tried
char[512] too, in case it was supported, but it failed too.

uint32_t

Done.
