hashcat Forum

Hello!
I'm new here and I was just trying to use Hashcat to get my password back.
It is a rar file and I know part of the password. 
This line bellow is from the code I was trying to run with CMD (I already have the hash):

hashcat.exe -m 13000 -a3 hash 321654?s?s?s

The point is, I know it starts with "321654," and the last three characters are somewhere in this sequence: /?1!2@3#.

Can anybody help me please?

Try this. It uses a custom charset to set `?1` to your `/?1!2@3#.` list:
hashcat.exe -m 13000 -a3 hash -1 "/??1!2@3#." 321654?1?1?1

Good luck!

Any idea what happened?? 
I tried to change some numbers and characters to see if it would work, but it didn't go right...

Sorry for the late reply. You need two question marks, like ?? in the charset, as in my example as ? is a special character that needs to be escaped. Rather strange and silly, I know. If that doesn't fix it and you know for sure that the password is in that search space (similar to the `Candidates`), something may have gone wrong, but from what I can see, the password just simply isn't what you may have believed it to be. You could try making a rar with a known password to see if that cracks, like "321654?#4" or something
