Using non-Jumbo, you need to run on a host supporting the crypt() library call *and* that supports sha512crypt using it. The solution is building a fresh "bleeding edge" Jumbo for Windows. You should do so for Linux too since the sha512crypt format is at least 2x faster than the generic crypt format. Building on Windows is a challenge compared to most other systems. There are instructions at http://openwall.info/wiki/john/tutorials/win64-howto-build but they are not 100% updated. For a starter, the "make -j4 win64-cygwin-x86-64" should be replaced with "./configure && make -sj4". I can't be arsed to touch that OS so I won't update the wiki. But others here do use Windows so just try it and come back with any specific questions. magnum
