Question 
Hello everybody here is anybody who can correct me.
I m using The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali)-linux-1.0.6 and got MySQL Password Hashes.
So I need help in cracking them.
Here is what i done :
Code:
hashcat -m 300 -a 3 -1 ?a?a?a?a?a?a /root/Desktop/allhashes.txt mask

This code executes but not working.
My hashcat Version is 1.47

-1 is used to define a charset, not the mask itself
And replace "mask" in your command line with the actual mask, so :

Code:
hashcat -m 300 -a 3 /root/Desktop/allhashes.txt ?a?a?a?a?a?a
