CL_DEVICE_NOT_AVAILABLE - KeePass pass recovery

[rboyhan]

Hi Everyone;

I'm looking for some help trying crack my KeePass password.  My Apple iPhone upgraded and my old version of KeePass stopped working and I can't remember what my master password is.  I've been working now for about 2 weeks trying to get JohntheRipper and now hashcat to find my master password.  It has not been easy, but I finally got hashcat to actually run in Lubuntu running inside Vmware Fusion.  But now I stuck and don't understand the results I'm getting.  When I execute hashcat is runs very fast, which I believe is telling me it's failing to run.

Below is what the program outputs.  Can someone tell me what I might be doing wrong?

root@lubuntu:/home/lubuntu/hashcat-6.2.2# hashcat -m 13400 -a 0 ./MasterHash.txt ./rockyou.txt
hashcat (v6.2.2) starting...

Thank you for the help.

Well regarding your output, your Device 1 (CPU) was skipped because Hashcat uses GPU by default

try adding option -D 1,2 to tell hahscat to use also CPU, but dont think it would run fast, see example output in benchmark, instead of using rockyou, try to remember your passwordstyle and build your own dict or mask and apply rules
