With the current code, you can't have "incremental" mode both go beyond the length of 8 and use 8-bit characters at once - you have to choose one of these. (I have specific plans on addressing this limitation.) To have it support 8-bit characters (but remain limited to lengths of up to 8) use these settings: http://www.openwall.com/lists/john-users/2008/03/17/1 Obviously, you will need to generate a new .chr file as well. Alternatively, you may use an external mode, which will let you go for lengths beyond 8 and for 8-bit characters at once (although this might be taking too long if your charset is large): http://www.openwall.com/lists/john-users/2008/03/17/2 Unfortunately, an external mode won't play nicely with the existing MPI patch, so you'd need to use another approach to distribute the workload across your CPU cores - e.g., by combinations of character set and password length. The "single crack" and wordlist modes do not have any of these limitations, so you may just use them for lengthy and 8-bit passwords. This was probably obvious to you, but I mention it for others who might come across of this posting. Alexander
