You need to prefix them with the username and a colon, sort of like
/etc/shadow i.e.:

root:247a3993f32ffc44556b20bc951de6cb
user1:c5e60c3af1d2361d6848e5aea666102b
user2:jamZ4RyrrWDLw
...

The additional data in /etc/passwd could also improve password
guesses, but it's completely optional.

(P.S: try the documentation first)
