THIS IS AN AUTOMATED BUILD OF JOHN THE RIPPER FOR DOCKERHUB
This is the github repository for https://hub.docker.com/r/adamoss/john-the-ripper
USAGE
YOU NEED TO MOUNT THE FILE YOU WISH TO CRACK USING -v
DOCKER CANNOT MAGICALLY READ THE HOST FILE SYSTEM SO PLEASE REMEMBER TO PASS THE MOUNTS TO THE CONTAINER
docker run -it -v `pwd`/yourfiletocrack:/crackme.txt adamoss/john-the-ripper /crackme.txt
in the above example docker is mounting your file to crack inside the container as /crackme.txt then it passes /crackme.txt to john
wordlist rockyou.txt is in /usr/share/wordlists/rockyou.txt so you can pass options to john at will
docker run -it -v `pwd`/yourfiletocrack:/crackme.txt adamoss/john-the-ripper --wordlist /usr/share/wordlists/rockyou.txt /crackme.txt
if you want to enter without launching john
docker run -it adamoss/john-the-ripper /bin/bash
