I'm trying to get hashcat running, but seem to be having some issues.

I'm following this guide for Ubuntu:
https://techglimpse.com/password-cracking-with-hashcat/

Using this installer:
https://hashcat.net/files/hashcat-3.10.7z

In addition to the guide, I did:

install ocl-icd-libopencl1

apt-get update && sudo apt-get upgrade

I get this error on the included example files:

root@ip-139-28-11-15:~/new/hashcat-3.10# hashcat example0.hash example.dict

hashcat (v3.10) starting...



Generating bitmap tables with 16 bits...



ERROR: clGetPlatformIDs(): CL_UNKNOWN_ERROR

My OS is:

Linux ip-139-28-11-15 3.13.0-57-generic #95-Ubuntu SMP Fri Jun 19 09:28:15 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

I don't know what to do. Any help?

Intel CPUs require OpenCL Runtime for Intel Core and Intel Xeon Processors (16.1.1 or later). Download and install OpenCL™ Runtime latest from intel website. Ignore the compatibility warning.

I just built hashcat on ubuntu 16 using the following commands.

git clone https://github.com/hashcat/hashcat.git

sudo apt install hashcat

sudo apt install cmake build-essential

sudo apt build-dep hashcat

cd hashcat

git submodule update --init

make

ls

./hashcat  --version

I encountered this error while creating a tutorial on how to install hashcat on Ubuntu 18.04; I've included the instructions below for Installing OpenCL™ Runtimes for Intel® Processors- feel free to review my full gist on GitHub. Hope that helps!

Installing OpenCL™ Runtimes for Intel® Processors

Installing OpenCL™ Runtimes for Intel® Processors - Option A (Recommended)

1. Check your CPU system processor architecture by running sudo lscpu to identify the class of CPU e.g. "Intel (R) Core (TM) i7-7700 CPU @ 3.60Ghz"- alternatively, you can go to Settings > Details which will also reveal the CPU-family (e.g. Intel (R) HD Graphics 630 (Kaby Lake GT2)).


2. Go to the Intel Developer Zone and scroll down to the corresponding download link for your system; assuming you're running Ubuntu 18.04 and have a Intel Core-class CPU, scroll down to "Linux* OS Ubuntu* 16.04.x (deb)" and click on the Github link for 18.46.11837 Runtimes to access the runtime-packages to download.


3. There should be instructions within the aforementioned Github repo- or you can proceed with the following in the next steps.


4. cd ~/Desktop


5. mkdir neo


6. cd neo


7. sudo wget https://github.com/intel/compute-runtime/releases/download/18.46.11837/intel-gmmlib_18.4.0.348_amd64.deb


8. wget https://github.com/intel/compute-runtime/releases/download/18.46.11837/intel-igc-core_18.44.1060_amd64.deb


9. wget https://github.com/intel/compute-runtime/releases/download/18.46.11837/intel-igc-opencl_18.44.1060_amd64.deb


10. wget https://github.com/intel/compute-runtime/releases/download/18.46.11837/intel-opencl_18.46.11837_amd64.deb


11. Install the packages by running sudo dpkg -i *.deb.


12. Restart the system by running sudo reboot.

Installing OpenCL™ Runtimes for Intel® Processors - Option B

1. Go to Intel OpenCL Runtimes website and scroll down to the bottom of the page to Download Intel CPU Runtime for OpenCL Applications 18.1 for LINUX OS (64-bit only).


2. After downloading the OpenCL Runtimes for Intel Processors, cd ~/Downloads
   


3. Run sudo tar -xzf l_opencl_p_18.1.0.013.tgz to unpack the tgz file- please note, the OpenCL file version may update since the time as of this gist (ie as of this gist, the version is 18.1.0.013.)


4. cd l_opencl_p_18.1.0.013


5. Run sudo ./install.sh
   


6. A welcome screen is prompted- hold-down the "Enter" key until able to input select "2" for "I do NOT consent to the collection of my Information"


7. Hit "1"


8. Hit "1"


9. Hit "Enter" and then restart the computer.


10. If any additional Intel OpenCL errors are encountered after testing hashcat, go to section 'Installing OpenCL™ Runtimes for Intel® Processors - B'- if not, proceed with section "Testing Hashcat"
