- AES-256-XTS for contents and AES-256-CTS-CBC for filenames
- AES-128-CBC for contents and AES-128-CTS-CBC for filenames
- Speck128/256-XTS for contents and Speck128/256-CTS-CBC for filenames
It is strongly recommended to use AES-256-XTS for contents encryption.
AES-128-CBC was added only for low-powered embedded devices with
crypto accelerators such as CAAM or CESA that do not support XTS.
Similarly, Speck128/256 support was only added for older or low-end
CPUs which cannot do AES fast enough -- especially ARM CPUs which have
NEON instructions but not the Cryptography Extensions -- and for which
it would not otherwise be feasible to use encryption at all. It is
not recommended to use Speck on CPUs that have AES instructions.
Speck support is only available if it has been enabled in the crypto
API via CONFIG_CRYPTO_SPECK. Also, on ARM platforms, to get
acceptable performance CONFIG_CRYPTO_SPECK_NEON must be enabled.
New encryption modes can be added relatively easily, without changes
to individual filesystems. However, authenticated encryption (AE)
modes are not currently supported because of the difficulty of dealing
