unshadow - combines passwd and shadow files
This manual page documents briefly the
command, which is part of the john package.
This manual page was written for the Debian GNU/Linux distribution
because the original program does not have a manual page.
john, better known as John the Ripper, is a tool to find weak
passwords of users in a server.
The unshadow tool combines the passwd and shadow files so John can
use them. You might need this since if you only used your shadow file, the
GECOS information wouldn't be used by the "single crack" mode, and also you
wouldn't be able to use the '-shells' option. On a normal system you'll need
to run unshadow as root to be able to read the shadow file.
The programs are documented fully by John's documentation,
which should be available in /usr/share/doc/john or other
location, depending on your system.
