IMHO, should take file(s) as input, or stdin. Also, it should support (but not require) a login field and possibly extra fields, just preserving them:




The enclosed patch implements the above.

I also think we should take the opportunity for this same utility to support reading pristine cisco configuration files and outputting hashes (both type 5 and type 4) in john format. I haven't done that yet. A sed line that extracts type 5 is here: but it does not catch all cases iirc.
