Under FreeBSD, /etc/master.passwd is what holds the passwords for the users. It also has some additional fields not found in SysV type password files. /etc/passwd, /etc/pwd.db, and /etc/spwd.db are all created from /etc/master.passwd. It should be possible to write a script to merge the encrypted passwords passwords from /etc/shadow and the rest of the entries in /etc/passwd into the proper format (man 5 passwd). A good crack program is John the Ripper.
