AES-XEX is a building block for other cryptographic standards and not yet a standard in and of itself. We'll just provide the standardized AES-XTS algorithm, and not AES-XEX. The AES-XTS algorithm and interface provided can be used to perform the AES-XEX algorithm when the length of the input is a multiple of the AES block size.
