Format 6 and 7 are 'somewhat' the same. There are 2 stipulations put on
format 7. The first is that the salt MUST be 3 bytes long. This stipulation
is not part of format 6.
Format 6 does work with 3 byte salt, and will also work with longer salts.
I think the max is 25 byte salt (for length reasons). If you need a salt
longer than 25 bytes, then you will have to build a non-sse build of john.
Also, the other stipulation put on format 7, is that it REQUIRES using a
separator char other than the ':' character. Any format in md5_gen 'can'
use a separator other than ':'. To do that, you have to build the input
file properly, and then use the -fie= command line switch. However, format
7 is written in a way that you are forced to do that.
So, you can easily run all that you want, by using the format md5_gen(6).
If you do not have any salts with the ':' in them, then you are not 'forced'
to use the -fie switch.
Jim.
