| It's a management requirement.  The manager sees "AES128" and "AES256"
| and thinks "256 must be better than 128" and therefore the edict comes
| down that AES256 must be used.  It's not a technical decision.  It's
| not a decision made by analyzing the threats.  It's made purely
| by assertion, but it's a decision that can't easily be refuted.
Well, there's a very easy answer to that one:  Tell the manager
involved that the number is the price.  "You can have the industrial
grade one for 128 bucks, or the one done to MIL specs with gold plating
for 256 bucks."  :-)
