Subject: Password file hash type analysis in JtR

John Users,

I know that Unix/Linux and Windows password files can have multiple hash
types in them, I think the following output/utility would be useful in JtR.

I'm not sure if it would be best served as a separate utility, or added
functionality to the JtR executable.

Potential new output:

The following password hash format(s) was/were discovered in the input file
<file>:

<format1>

<format2>

...

<formatx>

Line(s) 1-30 contained <format1> type passwords

Line(s) 31-60 contained <format2> type passwords

...                                               

Line(s) 61-90 contained <formatx> type passwords

What do you think?
