Quickly hacked together via an interactive docker shell. Will probably switch to a clean Dockerfile soon.
I use it with:
$ sudo docker run -it -v /some/host/path:/some/container/path puerkitobio/crack
And write my crack code in my host (in
/some/host/path) and compile in the container (because I run Arch Linux with a gcc 5.1 compiler that has a bug with the Crack 0.10 code - the image uses gcc 4.8 in Ubuntu).
