Hi
is there a way to guess how many passwords in a wordlist my GPU can try?
i saw there is a benchmark option and speed only time
is it one of these?
meaning i want to know if i have a word list like rockyou and i tried it on an md5 hash how many passwords my PC can try in a second.
The best way to do this is to perform an actual run.
Raw wordlist mode (with no rules) is very, very fast. hashcat's guessing speed is so fast that it can often spend more time caching a large dictionary than the actual guessing:
Code:
$ echo en 'hashcathashcat' | md5sum | awk '{print $1}'
38f63c3a621ad108457843529feec46a
$ ./hashcat -m 0 -a 0 -w 4 38f63c3a621ad108457843529feec46a really-big-wordlist.txt

You're looking for --speed-only

Hey
i didnt understand what command have you tried

Hey
i tried to do that and got this
Speed Dev 65500 kH/s
that means that it tries 65550 passwords in a second from the word list?
isnt that slow?
im trying one hash using md5 with a0 attack
thanx
Yes, that is very slow. If you use wordlists instead of brute-force you need to add an amplifier to get full speed on GPU.
How come with speed-only i get 65K results (image1)
and in the actual attack it goes down much less 4302 (image2)
so what is the right speed , meaning how many passwords from list my PC ties?

Speed was lower because you cracked the password immediately, didn't get a chance to do any work. Moreover, as was already mentioned, you need to add an amplifier to gain any acceleration.

What is that mean amplifier?
also am im doing the right command to check my PC to see how many passwords he can try in a word list?
im using
Code:
hashcat64 -m0 "my hash" wordlist.txt --speed-only
or should i use something else
