E.g. password must be 8 characters long and must contain at least 1 letter (all upper or lower), 1 digit and 1 special sign ? I've searched the FAQ/wiki and tried it with the external filters but: 1. I experience a huge performance inpact (~20%). As far as I understand the filtering is worth it because not that many words are being hashed but limiting the charset before the generation of the words would be better, right? But on the other hand I do not want to loose the presumption of the charset... Any solutions for that? 2. John still tells me "Warning: mixed-case charset, but the current hash type is case-insensitive; some candidate passwords may be unnecessarily tried more than once." - how to tell the word generator? :) Thanks for your help and time Max
