Hey,
  I've used JtR to crack a whole lot of Finnish and Swedish passwords so I know it works. It seems like your test hashing function is the problem. Aka when I hash "müllerkill" to MD5 I get the following:

a75cf6836c4524621d4c09d35aa10767

Then when I run JtR it managed to crack the password. I've always had a problem where JtR doesn't print the correct value out to the screen. I think this is a C problem, (or a locale issue), and not a JtR problem since I've dealt with that before on some of my own code. Aka it will print the cracked hash as "m?llerkill" but if I manually check the .pot file it will have the correct value, aka "müllerkill".

I hope this helps.

Matt

Hi

 I use JTR 1.7.3.4 patched with JimF patch for 1.7.3.4-jumbo-2

 My dico.txt is utf-8 (only 1 word inside  "müllerkill" )
 My hash.txt is utf-8 (only 1 hash 66259539a45ac8aa62105ea6d91fad41 ), 
66259539a45ac8aa62105ea6d91fad41 = müllerkill

 I did ./john -format=raw-md5 -w:dico.txt hash.txt

 This is the log :

 guesses: 0  time: 0:00:00:00 100.00% (ETA: Sun Dec 13 16:16:48 2009)  
c/s: 100  trying: müllerkill

 hash not cracked :-/

 How can you explain that ?

 Thanks.
