Dòng [53/1115]:
// Instead of using activate_replay_protection(), you can use activate_sequence_protection() (receiving side) and set_next_send_sequence_id(). They are very similar; but, the sequence number code isn't tested, and is problematic if you may have multiple clients that don't share storage (you can use the current time as a sequence number, but if two clients send at the same millisecond (or whatever granularity you use), you may have problems); whereas the replay protection code relies on database storage on the sending side (not just the receiving).
