• Install CMake

  • Download from https://cmake.org/download/
  • Install it, ensuring CMake is avaiable on the system path at least for the current user performing the build.

• Install Visual Studio 2017 Community Edition. You can get this for free from Microsoft with the Dev Essentials Program: https://my.visualstudio.com/Downloads?q=visual%20studio%202017&wt.mc_id=o~msft~vscom~older-downloads

• Install CUDA SDK

  • Download from https://developer.nvidia.com/cuda-downloads
  • Run the installer with default settings, or with custom settings, leaving off 'GeForce Experience' if you want to reduce bloat.

• Install Qt 5.12.11

  • Download the online installer from https://www.qt.io/download-qt-installer
  • Run the installer and choose the 'Archive' category, use Qt 5.12.11, MSVC 2017 32-bit and 64-bit builds, and include sources for debugging purposes, and Qt Debug Information Files
  • Note the location where it is installed, typically in the folder C:\Qt

• Install NSIS

  • Download the NSIS installer (3.08 or newer) from https://nsis.sourceforge.io/Download
  • Add the NSIS plugin:
    • nsProcess from https://nsis.sourceforge.io/NsProcess_plugin. Get the v1.6 version and put the dlls in your C:\Program Files (x86)\NSIS\Plugins folders in the appropriate places, renaming nsProcessW.dll to nsProcess.dll for the unicode version
    • ShellExecAsUser plugin from https://nsis.sourceforge.io/ShellExecAsUser_plug-in, get the 'Unicode Update' version and install the same way as nsProcess

• Choose a root folder for the repository. Windows often has path length limitations so pick something short, like C:\ if possible

  cd /d C:\
  

• Clone the project recursively

  git clone --recurse-submodules [email protected]:L0phtCrack/lc7.git
  

• Set up jtrdll

  • You should be using git for windows bash shell for this, or a compatible bash shell for windows
  • Run cd lc7/external/jtrdll
  • Run ./dynamic_big_crypt_generator.sh

• Run the setup script, pointing it to the location of Qt (ensure you are using a default CMD command prompt with no MSVC environment settings)

  cd lc7
  setup C:\Qt
  

  This will build OpenSSL and configure all of the project dependencies

• Build the 'L0phtCrack Remote Agent' for Windows, by opening the lc7\win-agent\win-agent.sln solution file in VS2017 and building all configurations (use batch build, select all to build every combination of the agent)

  • This will likely fail at the 'signtool.exe' build step because code signing certificates cost money and there is no 'LetsEncrypt' for code signing yet, and you don't have the cert/private key for l0phtcrack.

• Build the 64-bit 'L0phtCrack 7' project by opening lc7\build_win64\L0phtCrack 7.sln and compiling it

• Build the 32-bit 'L0phtCrack 7' project by opening lc7\build_win32\L0phtCrack 7.sln and compiling it

• Build the RelWithDebInfo versions of the Windows x86 and x64 builds of L0phtCrack
• Run a VS2017 Native Tools Command Prompt and ensure signtool.exe is in your path.
• Also ensure Python 2.7.14 is in your path
• cd to tools\releasetool and run:
  • 'python releasetool.py buildinstaller release64`
  • 'python releasetool.py buildinstaller release32`
• This will likely fail at the 'signtool.exe' build step because code signing certificates cost money and there is no 'LetsEncrypt' for code signing yet, and you don't have the cert/private key for l0phtcrack.
