Details:
We know grub can open encrypted volumes with luks or geli headers.
Is it possible to specify AES-XTS encrypted volume without luks/geli?
For instance: my main lvm's pv volume is defined with dmsetup as:
sda_crypt: 0 12345678 crypt aes-xts-plain
0000000000000000000000000000000000000000000000000000000000000000 0 8:0 409600
and I would love to map is with something similar to (nonexistend) command:
cryptomap (sda_crypt) 0 12345678 --cipher=aes-xts-plain
--key=0000000000000000000000000000000000000000000000000000000000000000
--dev=(hd0) --offset=409600
I think it should be possible by making an easy patch to
grub-core/disk/cryptodisk.c but perhaps it is not necessary, is it?
