        True enough.  However, thats an argument for 3des, not for
des.  When avoiding des, there are two possible motivations: speed and
security.  If your motivation is speed, your analysis is probably
fautly.  However, if you really believe that speed is paramount, there
are better choices than DES.  If security is why you're using
cryptography, then 3des is a clear choice.  Didn't I list 3des in my
list of strong ciphers?
