Re: cryptsetup mistakenly includes newline character in passphrase

Hey.

In your script, you create the volume via:
> printf "%s\n" "${PASSPHRASE}" | cryptsetup "${cmd_cryptsetup_params[@]}" --type=luks2 luksFormat ${DEVP}5 -

With the "-" in the end meaning "read the key file from stdin"... so it
takes up everything presented (up to some compiled-in maximum).

There you have a trailing "\n" in the printf.


When opening you also read a keyfile from stdin, but you don't give a
trailing "\n":
> printf "%s" "${PASSPHRASE}" | cryptsetup --verbose --debug --key-file - open ${DEVP}5 debug_open


Cheers,
Chris.
