Yes, there are full 8-bit hash types. John mostly supports these just fine. This limitation of the "incremental" mode in the default build of John is one of the few issues that do exist. However, NTLM hashes (MD4-based) use Unicode (UTF-16 or UCS-2? I'm not sure). The current contributed patch for JtR for the support of those hashes only handles 8-bit characters (expanding them to Unicode), but not any other Unicode characters (are these allowed in Windows passwords?) > maybe it would be possible to generate a few more charset-files for > different european languages or even a "all-256-asciis.chr" ?? I don't have sufficient statistical information on passwords which use characters outside of the US-ASCII set. If you're OK with not trying these passwords in an optimal order, then just use an external mode - such as the "8bit" mode from this posting: http://article.gmane.org/gmane.comp.security.openwall.john.user/414 P.S.
