I don't know anything about yad, but here's what worked for me some
years ago:
echo -n "passphrase" \
| cryptsetup --key-file="-" luksOpen /dev/sda5 name1
Replace /dev/sda5 with whatever the relevant device name is.
Let us know if this works for you. (Hope it does.)

i have been to so many forums to find a solution to this. all the
variations are confusing me and none are working.
i am trying to pipe a passphrase to cryptsetup using yad.
pass1=`yad --form --title="Enter container passphrase" --height=50
--width=350 --field=Password:H`
then i strip out the pipe character present between yad variables
pass="${pass1//|}"
at this point the variable pass appears to be exactly what i want.
later on i invoke cryptsetup with the passphrase variable piped to it.
echo "$pass" | cryptsetup --cipher aes-xts-plain --key-size 512 --hash
sha512 --iter-time 5000 --use-random luksFormat "$container" -
after a moment, i see the device pop into the selection in my file
manager then it dissapears.
the funny thing is, i wrote a terminal only version using the same
methods minus the yad things and it works fine(see attached)
terminal version requires 3 confirmations YES, passphrase, passphrase.
do i need to reproduce these confirmations even with a minus sign at the
end of the cryptsetup line?
if so, would echo "YES"$'\n'"$pass"$'\n'"$pass"'\n' do this?
also, if i replace the echo "$pass" pipe with xterm -e cryptsetup.... it
works fine. basically, i am not getting the password format piped
correctly. ive seen 7 different variations on this pipe and nothing is
working. its probably something with spaces but i am resorting to email
to lower my bloodpressure. also avoiding forums to lower my heart rate :)
thanks to anyone reading this.
