Locked out of Keepass 1.x

[AConcernedLad]

Hi.

I've managed to lock myself out of my own KeePass database. I know some details about length and characters used so I can whittle it down to a reasonable bruteforce.

My only issue is that I'm unable to crack the example hash on the front page despite supplying the following input:

Code:

./hashcat64.exe -m 13400 -a 3 $keepass$*1*50000*0*375756b9e6c72891a8e5645a3338b8c8*82afc053e8e1a6cfa39adae4f5fe5e59f545a54d6956593d1709b39cacd7f796*c698fbfc7d1b71431d10611e2216ab21*24a63140f4eb3bfd7d59b7694eea38d1d93a43bc3af989755d2b326286c4d510*1*192*1a65072f436e9da0c9e832eca225a04ab78821b55d9f550860ade2ef8126a2c4050cf4d033374abd3dac6d0c5907c6cbb033643b203825c12e6c9853b5ac17a4809559fe723e01b4a2ab87cc83c8ba7ee4a757b8a0cf1674106f21f6675cba12064443d65436650df10ea0923c4cadfd4bfe341a6f4fa23a1a67f7d12a489fc5410ef6db9f6607905de491d3b3b915852a1b6c231c96366cbdee5ea9bd7f73ffd2f7a579215528ae1bf0ea540947ebfe39ca84bc6cbeded4f8e8fb6ed8f32dd5 ?l?l?l?l?l?l?l

Which yields the following output:

Code:

I'm not quite clued up as to what that means and why it is occurring.

I've tried the very basic MD5 one too and that's working for me alright so I'm not entirely sure what is happening with the KeePass hashes in particular.

Any help would be greatly appreciated.
