Hello, everyone:
i add one line in the setkey function which is in xts.c file to
print the in_key value. I find the key value not same i set in the
keyfile by cryptsetup

# cryptsetup luksFormat -d my_keyfile -c xts-aes-plain -s 256 /dev/loop0
# cat my_keyfile
1234567890abcdef1234567890abcdef
I want to know how i set my key to encrypt/decrypt the disc for
xts-aes and aes alogrithm? And how the crypto get the real key to
encrypt the disc or how the key printed in the setkey is genereted and
when? Thanks very much!
