Acording to Freebsd's
geli(8) AES-CBC with keylength of 192 is supported:
Code:
-e ealgo Encryption algorithm to use. Currently sup-
ported algorithms are: AES-XTS, AES-CBC,
Blowfish-CBC, Camellia-CBC, 3DES-CBC, and
NULL. The default and recommended algorithm
is AES-XTS. NULL is unencrypted.
-l keylen Data Key length to use with the given crypto-
graphic algorithm. If the length is not spec-
ified, the selected algorithm uses its default
key length.
AES-XTS
128, 256
AES-CBC, Camellia-CBC
128, 192, 256
Not much time at this moment, but I cannot find anything which byte-order UFS2 is using and/or whether it is processor architecture dependent.
