Hi,
This is to announce several things at once:
0. Besides staying on this mailing list, it is now possible to receive
more timely updates by following us on Twitter:
http://twitter.com/openwall
I've already made a few initial tweets to set the expectations.
1. A new version of our password/passphrase strength checker,
passwdqc 1.2.2, has been released. This version makes minor Makefile
updates to make the "install" and "uninstall" targets with their default
settings friendlier to Solaris systems:
http://www.openwall.com/passwdqc/
At the same time, a wiki page with detailed Solaris-specific
instructions on setting up passwdqc has been created:
http://openwall.info/wiki/passwdqc/solaris
2. A Python package re-implementing some algorithms from passwdqc has been
created by Alastair Houghton. It is found on the passwdqc contributed
resources list:
http://www.openwall.com/passwdqc/#contrib
http://alastairs-place.net/pwtools/
3. Detailed tutorials on cracking/auditing SHA-crypt hashed user
passwords on recent Ubuntu, Fedora, and Solaris 10 systems have been
posted to the john-users mailing list, separately for Linux (using
Fedora 12 as the specific example):
http://www.openwall.com/lists/john-users/2010/06/20/3
and for Solaris 10:
http://www.openwall.com/lists/john-users/2010/06/20/2
These include optional OpenMP parallelization instructions and examples
(to use multiple CPUs and/or CPU cores). (These same instructions will
work for bcrypt and SunMD5 hashes as well.)
4. The jumbo patch for John the Ripper has been updated further to
revision 1.7.6-jumbo-3, and the MPI parallelization patch has been
updated to apply on top of this revision:
