As mentioned in other mail, it can read passphrase from stdin,
also keyfile is supported.
But for these types of applications is better use libcryptsetup,
you can better control which buffer contain passphrase so you can
wipe it. Also locking of memory (avoid to swap out memory
with sensitive data) is better controlled through library then
in some shell script.
An example of code snip to open LUKS device is here
