What I doing wrong?

[yota79]

Hi 

I try to understand and use hashcat to find password with bruteforce.

To try this I use winrar and I create a small archive with a password of only numbers (for the facility to find with my 6900xt) and set 12345678 as password.

I use rar2jonh on this archive to find the hash to use on hashcat.

This is my command, but hashcat not find the password. 

What I wrong?

hashcat.exe -m 13000 -a 3 $rar5$16$d8487b991f0789aeed02fa40388dfff9$15$f60afe80aae33f652c10eac3b38a4f4a$8$07d57b8102e75a84 '?d?d?d?d?d?d?d?d?'

for testing purposes use example hashes from this list

maybe as suggested here (nice way to push this btw) the rar2john tool is buggy, but as mentioned, thats no hashcat problem

Remove single quotes around the mask from your command line (and the extra question mark, though hashcat will warn you about that one).

UAO it's work removing the single quote from the mask (and also che the extra question mark that is a refuse)
