## From Source

### Install pre-requisites

mkdir -p ~/src

#### apt update

sudo apt-get update

#### Required stuff

sudo apt-get -y install build-essential libssl-dev git

#### Recommended (extra formats and performance)

sudo apt-get -y install yasm libgmp-dev libpcap-dev pkg-config libbz2-dev

#### If you have an NVIDIA GPU (OpenCL support)

# sudo apt-get -y install nvidia-opencl-dev

#### If you have an AMD GPU (or want to use CPU as OpenCL device)

##### Up to Ubuntu 15.10 (<# 15.10). This will work on Intel hardware but warnings will be seen.
sudo apt-get -y install ocl-icd-opencl-dev opencl-headers fglrx-dev

##### Ubuntu Xenial 16.04 LTS and above (># 16.04)
# The fglrx driver would not be supported in 16.04 (XServer 1.18 is not supported). Canonical and AMD decided to use the new hybrid driver stack for 16.04. JtR OpenCL users should stay on a supported release until the hybrid stack is available.

#### Optional MPI support

sudo apt-get -y install libopenmpi-dev openmpi-bin

#### Optional REXGEN support (additional cracking modes)

sudo apt-get -y install cmake bison flex libicu-dev
cd ~/src
