Hello,
First of all, thanks for this wonderfull piece of software. Ive been playing with it a bit and I am impressed.
However, I ran into some weird behaviour and was wondering if someone might have some insight.
I am cracking a rar file. To do this, I first generated some test files of which I know of course the password.
I noticed some of those were being cracked, some not. So I ran some tests and I noticed that rar files with longer passwords were not being cracked, even though the correct password was in the dictionary file?
I created for now several rar files (I tried attaching them, but is not allowed). The filename is the same as the password:
test.rar --> cracked
longertest.rar --> cracked
evenlongertest.rar --> cracked
evenevenlongertest.rar --> cracked
evenevenevenlongertest.rar --> exhausted
evenevenevenevenlongertest.rar --> exhausted
the process is the same everytime: extract hash with rar2john, than hashcat on extracted hash (I understand hashes need to be removed, so I did):
hashcat -a 0 -m 12500 '$RAR3$*0* REST OF HASH' password.txt
Same password file, which has the passwords (= filenames) of the above test files.
Am I missing something? Is there a maximum password length (if so, why no error is thrown, just exhausted?)?
Can anybody reproduce this maybe?
Many thanks,
