Subject: RE: Right Format to Load IPB hashes in JtR

Here is a patch against magnum-jumbo, which adds this new file (renamed to
raw2dyna), into the normal john source tree.  The source is in john's source
directory, and Makefile entries have been added, AND the dynamic documentation
lists the $HEX$ salt type, and this new 'tool'.
