Subject: [JtR patch] Fast cracker for Mozilla Firefox, Thunderbird and
 SeaMonkey master passwords.

Hi,

The attached quick patch does 320K c/s on a single core of AMD X3 720
CPU (OMP support is TODO). The earlier PoC cracker patch used to do
33K c/s and could not use OMP.

Usage:

1. Run "mozilla2john.py (Usage: ../run/mozilla2john.py <Mozilla
profile path>) on your Mozilla profile path"
2. Run JtR on above generated output.

However, I am getting the following warnings during compilation from
the DES code. Can someone take a look and fix them? Thanks!

mozilla_des.c: In function ‘DES_CBCEn’:
mozilla_des.c:751:2: warning: dereferencing type-punned pointer will

mozilla_des.c: In function ‘DES_CreateContext’:
mozilla_des.c:873:2: warning: dereferencing type-punned pointer will

I am hoping that this can go in jumbo-6. Please review.
