The main man page you want to look at is passwd(5), which documents the formats of the /etc/master.passwd and /etc/passwd file. In FreeBSD, the master.passwd file is the equivilent of the shadow file in Linux. What you want to do is convert the Linux password files to the master.passwd file in FreeBSD, and then run

    pwd_mkdb -p /etc/master.passwd

This will cause /etc/passwd to be built from /etc/master.passwd, and also cause the rebuilding of two hash files that cache the user data in a machine-readable format to improve performance, /etc/pwd.db (cache of passwd) and /etc/spwd.db (cache of master.passwd). You can use the -C argument to simply test if a file has the correct format and run sanity checking, which is useful if you want to test a conversion without possibly installing the results. Take a look at the pwd_mkdb(8) man page for details.
