...consider the case where 1/1000 keys is weak). Also, if you do a bit more work, you can come up with something like 3des. [mod: Now lets stop this cryptography discussion. - Weak keys should be prohibited: You don''t want to allow weak keys. If you think you''re using 3DES to get a 112bit key (Because you don''t trust 56 bits), then it is highly unfortunate if one of the keys turns out to be a no-op. Why does 3DES only use 2 keys and not three? Because you could use 3 keys and still only get 112 bits of security. Why does DES use 56 bits of key, and not say 64? Because DES h...

Hi, I''m using tc and HTB to shape my outgoing ADSL traffic. I was trying to make some graphs on the classes by meassuring the "sent bytes" of each class using rrdtool to store the data (as kbps after conversion). I expected that meassuring the root class I would get values similar that the ones I get measuring the interface counters but they differ by a large amount. Is
