   * \brief   This file contains AES definitions and functions.
   *
   *          The Advanced Encryption Standard (AES) specifies a FIPS-approved
   *          cryptographic algorithm that can be used to protect electronic
   *          data.
   *
   *          The AES algorithm is a symmetric block cipher that can
   *          encrypt and decrypt information. For more information, see
   *          <em>FIPS Publication 197: Advanced Encryption Standard</em> and
   *          <em>ISO/IEC 18033-2:2006: Information technology -- Security
   *          techniques -- Encryption algorithms -- Part 2: Asymmetric
   *          ciphers</em>.
   *
   *          The AES-XTS block mode is standardized by NIST SP 800-38E
   *          <https://nvlpubs.nist.gov/nistpubs/legacy/sp/nistspecialpublication800-38e.pdf>
   *          and described in detail by IEEE P1619
   *          <https://ieeexplore.ieee.org/servlet/opac?punumber=4375278>.
