Gilles Peskine 6d187afd8d psa_crypto does not support XTS
The cipher module implements XTS, and the PSA API specifies XTS, but the PSA
implementation does not support XTS. It requires double-size keys, which
psa_crypto does not currently support.

/*
* Context structure declaration of the Mbed TLS software-based PSA drivers
* called through the PSA Crypto driver dispatch layer.
* This file contains the context structures of those algorithms which do not
* rely on other algorithms, i.e. are 'primitive' algorithms.
*
* \note This file may not be included directly. Applications must
* include psa/crypto.h.
*
* \note This header and its content is not part of the Mbed TLS API and
* applications must not depend on it. Its main purpose is to define the
* multi-part state objects of the Mbed TLS software-based PSA drivers. The
* definition of these objects are then used by crypto_struct.h to define the
* implementation-defined types of PSA multi-part state objects.
