I have taken your advise and am running it with A-Z and have as well intentions to look into the "rules" doc to see what 5-9 in this instance means. john --wordlist=/home/Demian/RAID/txt/wpd8.txt --rules=truncate --session=truncate2 /home/Demian/RAID/recover -> 0g 52648p 0:00:07:24 47.43% (ETA: 18:10:31) 0g/s 118.3p/s 709.9c/s 709.9C/s AEaiitwAhbiapotwc..Awwmgdtcaahriafts So it might not take to long anyway... Thanks for your support and for keeping my hopes up =) Demian -- 'It's no measure of mental health to be well adjusted to a profoundly sick society.'
