> 15-char passwd lengths

15 lowercase character yields 1,677,259,342,285,725,925,376 possible passwds. that's about one and half nonillion. it happens to be roughly equal to the number of atoms in your body, or nearly a trillion times larger than the number of stars in the universe. in other words, it's a big, big, number. if someone were to write a program that tried to steal your passwd by guessing it, and the program were fast enough to try one million passwd a second, then it'd take that program 532,000 centuries to try every possibility. i'm kind of thinking that by the time that program's done running, you won't much care if anyone guesses your passwd!
