Keyspace on the back of an envelope

One question that always plagues me: should I use 32-bit or 64-bit keys. I can never make a firm decision on this point. But I’ve just done some back of the envelope calculations in thinking about it.

If you issued one thousand identities per second, it would take 50 days to exhaust the keyspace.
