While you're correct about the syntax, the above example obviously won't work for the default all.chr (which only has data for lengths up to 8), the MaxLen = 16 and CharCount = 95 combination wouldn't work because of the 64-bit integer overflow (one wouldn't be able to generate a *.chr file for these settings), and setting MaxLen beyond 8 doesn't make sense for traditional DES-based hashes anyway. I have already addressed all of these issues in more detail (including workarounds, where appropriate) in my other responses on this list. -- Alexander Peslyak <solar at openwall.com> GPG key ID: B35D3598 fp: 6429 0D7E F130 C13E C929 6447 73C3 A290 B35D 3598 http://www.openwall.com - bringing security into open computing environments
