something like that). If cycles on such a computer would be, say, 1,000 times more expensive than on your PC, then cracking the key would be 1,000*O(keysize^c) more expensive than generating it, not 1,000*O(c^keysize). Having a keysize of, say, 8 kbits instead of 1 kbit in this circumstance is not at all overkill; I would say this can be extended and made a general rule. You should always take some reasonable ammount of time(say 5 min) to encrypt your most sensitive messages, even if you have a 12 crays and a connection machene. The algorithim can be viewed as giving you an economic advantage, and worying over spending $.01 vs $.0001 is not just stingy, it is dangerous.
