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:

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:

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:
