Well, that, plus the fields for the change and expire times.

toor normally has a master.passwd entry of '*', meaning that password
authentication will always fail.

crypt(1) is intended for obfuscating file contents really, not for generating
password hashes (for that, you'd want crypt(3)).
The simplest way to do it would be to either copy the current hash from
/etc/master.passwd, or originally use *, and then change it with passwd(1).
You can generate password hashes with simple scripts, but that's slightly
more involved than I want to go into at the moment (I'm cooking dinner!).
