They are 8-bit characters, which are outside of the range supported for "incremental" mode by default. > how can do to get a charset with "è" "è" "à" "ç" and a-z ? If you really want to do it the way you tried to, then there's just one step you missed. You need to modify params.h as shown in this posting: http://www.openwall.com/lists/john-users/2008/03/17/1 Then recompile JtR and try again - it should work. However, since you don't seem to care to use the "incremental" mode for real anyway (that is, let its .chr file generation code examine some previously-cracked passwords or at least a wordlist), I suggest that you opt for a simpler approach. One of those would be to define a mode like: [Incremental:Alpha-fr] File = $JOHN/alpha.chr MinLen = 1 MaxLen = 8 CharCount = 30 Extra = éèàç This requires a recompile for the 8-bit chars too, but it does not require you to generate a custom .chr file. The 4 extra chars will be treated as the least likely, yet this shouldn't bother you. An even simpler approach, not requiring a recompile, would be to use the DumbForce external mode sample, configuring it for your desired charset. In the init() function, you'll specify: i = 0; c = 'a'; while (c <= 'z') charset[i++] = c++; charset[i++] = 'é'; charset[i++] = 'è'; charset[i++] = 'à'; charset[i++] = 'ç'; replacing the existing lines (many of them) defining another charset after the "This defines the character set." comment.
