Subject: Re: *2john conversion support

Note that the xxx2john scripts are like python and perl scripts so you have
to run them as separate processes somehow (many alternatives to do that,
like popen, fork, system etc) and save the output as an input file to john
itself. Most of the 2john scripts output one or more lines that john
understands. Also note that it is pretty hard to securely spawn an external
process. But the first step is probably to make it just work.
