Since the passwd command specifically doesn't permit this as a security 
feature, you can't.

You'll have to write a c program or use something like perl emulating 
what passwd does.  If you can't use expect, I see no other way.

This one-line perl script generates crypt(3C) strings...

#!/usr/bin/perl -w
# usage:    makepw password salt
#           "salt" is any two character string chosen from the set
[a-zA-Z0-9./]
# example:  makepw opENupwd a7
#           a7GGiQHDf8Auo
if ($#ARGV < 1) { print "usage: makepw.pl pwstring salt\n"; exit; }
printf("%s\n", crypt($ARGV[0], $ARGV[1]));

openssl or apg can generate des and md5 hashes of passwords.
With a simple sed script you can insert a des or md5 hash in 
/etc/shadow, but you must take care for an simultanous running passwd or 
similar, solaris dont have a vipw, or has it somewhere? Does anybody 
know how solaris take care for simultanous running passwd? Take a look 
at the source browser at opensolaris.com...
