Hi, there! Is it normal? Was it expected? v6.2.5 is slower than v5.1.0
Not just slower, but about 200 times slower! Of course, with my specific hardware/software/hash.
I am new to Hashcat. I'm using Windows and a 10-year-old laptop with an Intel Celeron CPU and an Intel GPU.
This CPU is a 3rd generation Intel processor, codename IvyBridge.
https://www.intel.com/content/www/us/en/...pencl.html
I was not able to use hashcat on Linux so far. Every time I got an "illegal hardware instruction" error.
MACs are synthetic (not real), for educational purposes only. Details are here
v5.1.0 took about 5 seconds.
Code: hashcat64.exe -D 1 -a 3 -m 16800 "ca5396d611cf330aebefd48ebbfb0e63*020000000001*020000000020*61703031" "12345678"
v6.2.5 took about 16 minutes.
Code: hashcat.exe -D 1 -a 3 -m 22000 "WPA*01*ca5396d611cf330aebefd48ebbfb0e63*020000000001*020000000020*61703031***" "12345678"
or
hashcat.exe -D 1 --deprecated-check-disable -a 3 -m 16800 "ca5396d611cf330aebefd48ebbfb0e63*020000000001*020000000020*61703031" "12345678"
Most of the time of those 16 minutes I see this message on the screen: Initializing backend runtime for device #1. Please be patient...
-D 1 means use CPU, works for both versions of Hashcat
-D 2 means use GPU, doesn't work in my case for both versions
v6.2.5 complains: Device #2: Not enough allocatable device memory for this attack.
v5.1.0 complains: Device #2: Intel's OpenCL runtime (GPU only) is currently broken. No devices found/left.
But it is possible to use GPU with v5.1.0 using option -D 2 --force
v5.1.0 took about 5 seconds.
Code: hashcat64.exe -D 2 --force -a 3 -m 16800 "ca5396d611cf330aebefd48ebbfb0e63*020000000001*020000000020*61703031" "12345678"

just a fast answer, your posted cli are a little bit messed up,
you provide hash plus plain password, but tells hashcat to bruteforce -a3 instead of -a0
could you test your commands with -a0 please,
alsa
NEVER EVER NEVER use --force unless you are a developer
--force will ignore all warnings and build in safety checks and therefore can or will produce wrong outputs

@Snoopy
Thank you for reply.
Simplicity is the reason for -a 3 (BruteForce) instead of -a 0 (Wordlist).
This way you can enter the password directly into the command line.
With -a 0 you need, first, create wordlist (dictionary) with passwords.
Second, you need to put the filename of wordlist into the command line.
If instead of
hashcat.exe -D 1 -a 3 -m 22000 "WPA*01*ca5396d611cf330aebefd48ebbfb0e63*020000000001*020000000020*61703031***" "12345678"
you try to enter
hashcat.exe -D 1 -a 0 -m 22000 "WPA*01*ca5396d611cf330aebefd48ebbfb0e63*020000000001*020000000020*61703031***" "12345678"
you will get
12345678: No such file or directory
For clarity I created dictionary file wordlist.txt containing three lines
1st-Line
12345678
3rd-Line-End
Then I tested with -a 0 and got similar results, please see below.
This time I used - Windows 7 (on Windows 10 the results are similar)
- hashcat64.exe v5.1.0
- hashcat.exe v6.2.5-207-gac1997027 from https://hashcat.net/beta/

If this is the last thing you see, hashcat hasn't started cracking yet, and you're spending 16 minutes waiting for the runtime to respond.

Yes, it seems so. But as a user I only care about the total running time. Why is this time significantly longer for hashcat v6.2.5 than for v5.1.0 ?

v6.2.5 requirement: "Intel CPUs require "OpenCL Runtime for Intel Core and Intel Xeon Processors" (16.1.1 or later)"
Not really clear what version you're running, but I don't see 16.1.1 anywhere.

as for the given cracking speed i didnt see any differences between 5.1 and 6.2.5, as PDO mentioned initializing runtime backend isnt your friend
take a look at your hashcat -I output it tells opencl 1.2 which is old it should tell
Code: OpenCL Platform ID #1
Vendor..: Intel(R) Corporation
Name....: Intel(R) OpenCL
Version.: OpenCL 2.1
Backend Device ID #1 (Alias: #2)
Type...........: CPU
Vendor.ID......: 8
Vendor.........: Intel(R) Corporation
Name...........: Intel(R) Xeon(R) Silver 4116 CPU @ 2.10GHz
Version........: OpenCL 2.1 (Build 0)
Processor(s)...: 48
Clock..........: 2100
Memory.Total...: 130722 MB (limited to 16340 MB allocatable in one block)
Memory.Free....: 65329 MB
Local.Memory...: 32 KB
OpenCL.Version.: OpenCL C 2.0
Driver.Version.: 18.1.0.0920
at least, see diff in opencl versiosn and driver version
second thing, runnning hashcat directly from C: is mostly a bad idea due to windows don't like such programs directly on the system drive, as im writing these lines and testing on windows myself i recognized some strange behavior from the windows defender (win 10 up2date)
windows defender gives repeatedly an popup (your admin advised some security online checking for an element or something similar) and hashcat isnt starting for a long time, i suspect the defender blocking hashcat and hashcat has to use something like a emulator layer to use the old opencl style instead
next thing to try, please update your opencl runtime from intel as DPO mentioned

Thank you for reply.
Yes, requirement for Hashcat v6.2.5
Intel CPUs require this runtime:
"OpenCL Runtime for Intel Core and Intel Xeon Processors" (16.1.1 or later)
However, the same for v5.1.0, v4.2.0, v3.6.0
Intel CPUs require this runtime and/or driver:
"OpenCL Runtime for Intel Core and Intel Xeon Processors" (16.1.1 or later)
In fact, I didn't install a separate OpenCL Runtime.
Instead, I installed the latest driver for my Intel HD Graphics 2500
https://www.intel.com/content/www/us/en/...15-33.html
This driver have OpenCL support.
It seems, there is no OpenCL runtime update for my CPU/GPU.
My notebook was manufactured in 2014.
My CPU was first introduced in 2013.

Probably only Jens Steube (atom) knows the real reason for this long initializing.
Initializing backend runtime for device #1. Please be patient...

yeah the GPU driver has opencl support but as i siad earlier, the intel opencl runtime for GPU (your used driver) is BROKEN !!! deinstall (a really clean deinstall) it and use the CPU only runtime 18.1 taken directly from the intel website
Intel® CPU Runtime for OpenCL™ Applications 18.1 for Windows* OS (64bit or 32bit)
anything else will not work
