Subject: Re: Re: [JtR PATCH] Support rar's -p mode by spawning
 external unrar process.

You can have a look at unrar's code. It's written in C++. Alternatively
have a look at libclamav source where they have ported that same unrar
source to C. Unfortunately I think the license might be  incompatible with
GPL - it's kind of public domain with the restriction that no compression
tool can be made of it. However, clamav is GPL'd so it is pretty confusing.

Mine is based on libclamav's code so it's nothing specific. I just had to
modify it and optimize it for password cracking purposes.
