It does generate candidate passwords like those you mentioned above for words containing the letter "a". > It's not what I want. > > As you can see I change swap letters also in this rule. > > what is the right syntax ? With 1.7.4+, you can use: /a sa[eiouy] Az"[0-9]\0\0\0" With the word "ward" in the input wordlist, it produces 50 candidate passwords like those you wanted: $ ./john -w=w --rules --stdout | head -3 words: 50 time: 0:00:00:00 100% w/s: 5000 current: wyrd9999 werd0000 werd1111 werd2222 $ ./john -w=w --rules --stdout | tail -3 words: 50 time: 0:00:00:00 100% w/s: 5000 current: wyrd9999 wyrd7777 wyrd8888 wyrd9999 If you also have similar rules that append just one digit, you could want to add a length check to this line such that it does not produce effectively duplicate candidate passwords for length-limited hash types (e.g., LM hashes): /a <- sa[eiouy] Az"[0-9]\0\0\0" This ensures that there's room for at least two characters to add to the input word. If not, it is assumed that adding the digits would produce an effective duplicate with a rule adding just one digit. > I read the john'rules without success. You could want to read the default john.conf as well (the updated one in 1.7.4). It includes the following lines: # Some three-digit numbers... -[:c] (?a \p1[lc] Az"007" <+ -[:c] (?a \p1[lc] Az"123" <+ -[:c] (?a \p1[lc] Az"[1-9]\0\0" <+ The last one of these three lines has replaced 9 separate lines (found in older revisions of the file), for appending "111" through "999".
