Subject: DumbForce init() function

Hi

 I have modified JTR to add french charset "é" "è" etc... with your 
help.

 It works fine, but I had to rebuild the alpha, alnum, all charsets 
(older with not compatible with). Now my JTR is less powerfull (crack 
less words in same time than yours), because original charset was 
highly optimized. I can't rebuild the same.

 There is an other way, to keep your highly charset, and add french 
char.

 You told me :
-------------------------------------------
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.
-------------------------------------------

 I'm really stupid with programming, could you add the code above (in 
differents rights place) in the john.conf and return me the john.conf 
correctly modified ?

 Thx
