git clone https://github.com/openwall/john.git
安裝代碼所需套件
sudo apt-get update
sudo apt-get install libssl-dev
sudo apt-get install build-essential
sudo apt-get install libbz2-dev
進入到src開始編譯安裝
cd john/src
編譯啟用gpu
./configure --enable-opencl
make -s clean && make -sj4
查看john有多少GPU CPU可以使用
./john --list=opencl-devices
使用4CPU 8RAM破解速度，破解五個英文小寫數字需要103小時
使用4個Tesla T4 GPU破解五個英文小寫數字只需10小時，速度快10倍(此7z檔案大小約為1G)
破解zip壓縮檔案
~/john/run/john --format=zip-opencl --mask=[mycharset.chr] --min-length=1 --max-length=12 solomon_hash.txt --devices=2,3,4,5 --fork=4
破解7z壓縮檔案
perl 7z2john.pl ~/japan.7z > japan7zhash.txt
如何遇到以下報錯代表缺少Compress::Raw::Lzma 模块

需要執行以下指令安裝缺少的套件
sudo apt-get install liblzma-dev
sudo cpan Compress::Raw::Lzma
