Subject: qustion about custom charset

Hello

I'd like to create custom charset for jtr with upper/lower alha + digits
and i'm expiriencing some problems with this procedure.
Whait i've done is:
1) deleted current pot file
2) generated wordlist with 3 signs and all comibnation for
lower-upper-alpha
3) generated des hashes for this wordlist
4) cracked entire wordlist withj john (all entrys in fresh pot)
5) runed john -make-charest=charset.chr

\run>john-omp.exe -make-charset=ula.chr
Loaded 238328 plaintexts
Generating charsets... 1 2 3 4 5 6 7 8 DONE
Generating cracking order... DONE
Successfully written charset file: ula.chr (62 characters)


6) in john.conf i've added:
 Code:

[Incremental:ula]
File = $JOHN/ula.chr
MinLen = 8
MaxLen = 8
CharCount = 62

7) After runing jtr with such configuration i think somehow it's avoiding
loweralpha signs...:

I've added my custom charset as attachement, for tests.

I'll be very grateful for any tips with this situation

Best regards
