It will not try all of the dates in your "UK/USA format", though (like "jim1231"). And it will try some non-dates. For those who don't know, the "<5" at the beginning of the above ruleset line tells John to apply the rest of the rules produced from this line only to input words that are shorter than 5 characters. This restriction may be desirable when both of the following two assertions are true: 1. The password hash type limits the length of passwords (or password halves, if applicable) to 8 characters. 2. Other ruleset lines exist that try appending fewer than 4 digits to passwords of 5 to 7 characters long. In order to implement this optimization yet not hard-code a maximum password length in the ruleset, the commands "<*", ">*", "<-", and ">-" may be used. For example: # Some [birth] years... l$1<-$9$[7-96-0]>- l$2<-$0$0>- l$1$9<-$[7-9]$[0-9] l$2$0<-$0$[0-9] l$1$9<-$[6-0]$[9-0] -- Alexander Peslyak <solar at openwall.com> GPG key ID: B35D3598 fp: 6429 0D7E F130 C13E C929 6447 73C3 A290 B35D 3598 http://www.openwall.com - bringing security into open computing environments
