See LICENSE file in tarball.
The main license of the package is attached; it is also used by packages net-analyzer/scanlogd and net-mail/popa3d. Since all these packages are hosted at openwall.com, I suggest that we use "Openwall" as the license's name.
It's obviously a Free Software license (even GPL compatible by a conversion clause), so it can be added to the MISC-FREE license group.
Feel free to fix it I suppose.
