I don't understand the above code, at all. The memset call apparently
means to zero out '*tun_key' (and throw away the conversion work we
just did) but the way it's written it only zeros out the pointer to
'*tun_key'. Either way, it doesn't make sense.

We don't put the return type on a separate line for a prototype, and
the parameter names shouldn't be used in this case, please see
CodingStyle.
Thanks,
Ben.
