- Hi,
-
- I've just started using Crack4.1 and I have a small comment on the
- contents of the dicts.rules file.
- The long list of substitutions from mycroft@gnu.ai.mit.edu does not check
- whether the substitutions are in the first eight characters of the word.
- Therefore, if a word has an 'a' in the ninth position, the rule '>2/asa2l'
- will replace this 'a' by a '2' which will be deleted anyway. This has the
- effect that many words made with this rule will be identical to words
- without replacements which have already been tested.
-
- Remedy is simple: change '>2/asa2l' to '>2x08/asa2l', so the word will be
- rejected if the character to replace is not in the first eight places of the
- word. Same for all the other rules of this form.
-
