-/**
- * \file aes.h
- *
- * \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>.

- *
- *        Due to the nature of CFB, you must use the same key schedule for

- *
- *              For OFB, you must set up the context with
- *              mbedtls_aes_setkey_enc(), regardless of whether you are
- *              performing an encryption or decryption operation. This is

- *              decryption.
- *
- *              The OFB operation is identical for encryption or decryption,
- *              therefore no operation mode needs to be specified.
- *
- * \note        Upon exit, the content of iv, the Initialisation Vector, is

- *              iv_off to 0 before the first call, and preserving its value
- *              between calls.
- *
- *              For non-streaming use, the iv should be initialised on each call
- *              to a unique value, and iv_off set to 0 on each call.
- *
- *              If you need to retain the contents of the initialisation vector,

- *
- *             Due to the nature of CTR, you must use the same key schedule
- *             for both encryption and decryption operations. Therefore, you
- *             must use the context initialized with mbedtls_aes_setkey_enc()
- *             for both #MBEDTLS_AES_ENCRYPT and #MBEDTLS_AES_DECRYPT.
- *
- * \warning    You must never reuse a nonce value with the same key. Doing so
- *             would void the encryption for the two messages encrypted with
- *             the same nonce and key.
- *
- *             There are two common strategies for managing nonces with CTR:
- *
- *             1. You can handle everything as a single message processed over
- *             successive calls to this function. In that case, you want to
- *             set \p nonce_counter and \p nc_off to 0 for the first call, and
- *             then preserve the values of \p nonce_counter, \p nc_off and \p
- *             stream_block across calls to this function as they will be
- *             updated by this function.
- *
- *             With this strategy, you must not encrypt more than 2**128
- *             blocks of data with the same key.
- *
- *             2. You can encrypt separate messages by dividing the \p
- *             nonce_counter buffer in two areas: the first one used for a
- *             per-message nonce, handled by yourself, and the second one
- *             updated by this function internally.
- *
- *             For example, you might reserve the first 12 bytes for the
- *             per-message nonce, and the last 4 bytes for internal use. In that
- *             case, before calling this function on a new message you need to
- *             set the first 12 bytes of \p nonce_counter to your chosen nonce
- *             value, the last 4 to 0, and \p nc_off to 0 (which will cause \p
- *             stream_block to be ignored). That way, you can encrypt at most
- *             2**96 messages of up to 2**32 blocks each with the same key.
- *
- *             The per-message nonce (or information sufficient to reconstruct
- *             it) needs to be communicated with the ciphertext and must be unique.
- *             The recommended way to ensure uniqueness is to use a message
- *             counter. An alternative is to generate random nonces, but this
- *             limits the number of messages that can be securely encrypted:
- *             for example, with 96-bit random nonces, you should not encrypt
- *             more than 2**32 messages with the same key.
- *
- *             Note that for both strategies, sizes are measured in blocks and
- *             that an AES block is 16 bytes.
- *
- * \warning    Upon return, \p stream_block contains sensitive data. Its
- *             content must not be written to insecure storage and should be
- *             securely discarded as soon as it's no longer needed.
- *
- * \param ctx              The AES context to use for encryption or decryption.
- *                         It must be initialized and bound to a key.
- * \param length           The length of the input data.
- * \param nc_off           The offset in the current \p stream_block, for
- *                         resuming within the current cipher stream. The
- *                         offset pointer should be 0 at the start of a stream.
- *                         It must point to a valid \c size_t.
- * \param nonce_counter    The 128-bit nonce and counter.
- *                         It must be a readable-writeable buffer of \c 16 Bytes.
- * \param stream_block     The saved stream block for resuming. This is
- *                         overwritten by the function.
- *                         It must be a readable-writeable buffer of \c 16 Bytes.
