I would think that any encrypted system out there today is nearly impossible
to crack since it can only be done via brute force (ie - guessing) and the
compute power required just isn't accessible to nearly everyone. Even the 50
cpu example you cite, is insignificant if they use a 4096 key (which certainly
is not unreasonable).

very few voice encryption systems use more than a 128 bit key. with
bruteforce attack a 128 bit key is certainly doable with a 50 cpu
distributed attack. should take about two weeks......


Me been there, done that.......
