IMHO, cisco2john.pl 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:

enable:LcV6aBcc/53FoCJjXQMd7rBUDEpeevrK8V5jQVoJEhU:::172.16.17.18:comments

->

enable:5e884898da28047151d0e56f8dc6292773603d0d6aabbdd62a11ef721d1542d8:::172.16.17.18:comments

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: http://www.openwall.com/lists/john-users/2006/05/14/8 but it does not catch all cases iirc.
