If you can't drive passed from redirected stdin (I'v not tried it) as in
this
passwd user <<ZZZ
passwd stuff here
ZZZ
then you can almost certainly drive it with expect; I've used expect with
telnet to good effect, I expect it will drive passwd too.
Failing all else, peruse passwd's source code and either adapt it to do
what you want, or lift the code that encrypts the password (I'ts probably
no more than a function call) and write a wrapper (in C) that takes the
password and writes the encrypted version to stdout.
