Subject: Re: Mac OS X 10.7 Lion password hashes (salted SHA-512)
Alexander,
I used your Perl script this morning on my original test user plist and it worked fine. I then changed the password of the user to something simple to make sure john could fine it. When running the script again, it came up with the error message, "Could not find a Mac OS X 10.7 Lion salted SHA-512 hash." I only changed the password to <tomorrow> from <Ydo!Ucar3>. I ran this on two different computers and it does the same thing. I'm attaching both plists for your review.
robert1new.plist is the one that doesn't work.

Rich, Jean-Michel, all -
Here's a trivial Perl script I just hacked together to process Lion's
plist files (such as /var/db/dslocal/nodes/Default/users/username.plist)
and print the hashes in a format directly usable by John 1.7.8-jumbo-7.
Usage:
./lion2john.pl < username.plist > username.hash
or for many files:
for f in *.plist; do ./lion2john.pl < $f; done > hashes

#!/usr/bin/perl
read(STDIN, $_, 1000000) || die;
($hash) = /bplist00\xd1\x01\x02\x5dSALTED-SHA512\x4f\x10\x44(.{68})/;
if (!$hash) {
print "Could not find a Mac OS X 10.7 Lion salted SHA-512 hash\n";
exit 1;
}
print unpack('H*', $hash), "\n";

Please test this on more plist files and report back.
Thanks,
Alexander
