- * This function computes the HMAC of the concatenation of \p add_data and \p
- * data, and does with a code flow and memory access pattern that does not
- * depend on \p data_len_secret, but only on \p min_data_len and \p
- * max_data_len. In particular, this function always reads exactly \p
- * max_data_len bytes from \p data.
- *
- * \param ctx               The HMAC context. It must have keys configured
- *                          with mbedtls_md_hmac_starts() and use one of the
- *                          following hashes: SHA-384, SHA-256, SHA-1 or MD-5.

- *                          next computation.
- * \param add_data          The additional data prepended to \p data. This
- *                          must point to a readable buffer of \p add_data_len
- *                          bytes.
- * \param add_data_len      The length of \p add_data in bytes.
- * \param data              The data appended to \p add_data. This must point
- *                          to a readable buffer of \p max_data_len bytes.
- * \param data_len_secret   The length of the data to process in \p data.
- *                          This must be no less than \p min_data_len and no
- *                          greater than \p max_data_len.
- * \param min_data_len      The minimal length of \p data in bytes.
- * \param max_data_len      The maximal length of \p data in bytes.
- * \param output            The HMAC will be written here. This must point to
- *                          a writable buffer of sufficient size to hold the
