Subject: 1.7.5-jumbo-1 builds for Win32 and Mac OS X

Hi,

Erik Winkler has contributed Win32 and Mac OS X builds of John the
Ripper 1.7.5 with revision 1 of the jumbo patch.  I've placed these into
the contrib/ directory and updated the links at:

http://www.openwall.com/john/#contrib

You may also find the files on Erik's website at:

The Mac OS X build is usable on a wide range of Mac hardware and
versions of Mac OS X - it is a universal binary with four architectures
and it is statically-linked against Erik's special build of OpenSSL.
Additionally, it uses faster bitslice DES S-box code for PowerPC with
AltiVec by Dumplinger Boy (Dango-Chu).

For some hash types, it may be preferable to run the "32-bit" version of
the code when you're on a 64-bit Intel-based Mac.  This is primarily
because some contributed "formats" (included in the jumbo patch) have
MMX or SSE2 optimized code for 32-bit mode only.  To invoke this version
of the code, you may run the universal binary through "arch -i386", e.g.:

arch -i386 ./john --test --format=pix-md5

For many other hash types, the above will actually hurt performance, so
only use it when you know what you're doing.

Erik - thank you!

Alexander
