@subsection Time synchronization
DPI systems can be active. They could intercept first (assuming
Time synchronization requirement could be used for preventing this.
Client and server clocks must be synced together more or less. You

accuracy (time window width) in seconds.
Each handshake's packet PRP authentication just XORed with current

+timestamp rounded to @option{timesync} number of seconds. Timesync option
is higher: less clock synchronization accuracy required, but bigger time
window of possible packet repeating.
