Now consider the password "maryhadalittlelamb"
let's see... under Unix - 8 character truncation "maryhada" also: implies password is definitely 8 chars long password taken from the set of all lowercase letters thus: set size of 26 symbols there are 26^8 = 208827064576 passwords of length 8 which comprise only of lowercase letters my dual-cpu 450MHz UltraSPARC-II can do 25000 crypts/sec/cpu - certainly more if i could be bothered to optimise the code. 50000 crypts/second total, on my desktop. 208827064576 passwords at 50000 crypts/sec = 4176541 seconds 4176541 seconds = 48 days 8 hours 9 minutes 1 second I can throw a rock from where I sit and hit about a dozen similar machines; say I can get ahold of 10 for simplicity. I can definitely crack your password in 4 days and 20 hours; on average I will manage it in a little over two days. ...so... I *do* hope you change your "secure" password on a weekly basis. - alec -- alec muffett, sun professional services, alec.muffett @ uk.sun.com bananas are not the only fruit
