md5_gen(6) and md5_gen(7) are the same thing, however, the md5_gen(7)
adds a couple of extra 'validations' when parsing an input line:
First, it stipulates that the salt MUST be 3 and only 3 characters
(shorter or longer will NOT be loaded).
Second, it will FORCE you to use a different separator char, since
the ':' IS a valid salt character in vBulletin hash/salt pairs,
and you WILL see them all the time for normal input.
But other than those 2 extra validations, 6 and 7 are the same. You
can use md5_gen(6) to crack vbulletin hashes just fine. It simply
will not 'hold your hand' validating that salts are 3 bytes, and that
you are properly splitting up the fields.

The only time you 'have' to use a character other than the 'default'
: as a line separator, is IF the format (the hash, or the salt, or the
user names, or other gecos fields) contain ':' characters. That is WHY
I added the ability to set it to something else. You can ALWAYS use a
different separator character and things 'will' work, but there is no
reason you 'have' to use a different character.
