I don't understand which field are useful for Johnny "hash type
suggestion/guessing".
I assume there will be a new column in the password table view after hash
in Johnny called "Type". And Johnny should write in the column format DES,
md5 etc. Is that right ?
If user click on button "Get hash type", I'll call ../run/john --show=types
../../t.pw

If I send a file, iIs it something that I need to send to stdin ? What does
this input do?

Everything in this might be wrong, I'm trying to understand by making
hypothesis after looking at the format. First, what is the $XXXX(dynamic_0)
thing doing before hash $0ed7dd550afb451ac5b94cb644310b0the ? Is it
important for johnny? Regarding the output, what does v means ? If we take
last line for example, I think the type is NT-old but what does :0:1:0:
stands for and is it important for our johnny feature ? Why is there line
without hash like Snefru-128:0:1:1:: and lines with  two types
MD2:0:1:1::mdc2:0:1:1:: (MD2 and mdc2) ?

Thanks a lot for your help !
