/** \brief Writes keys into the Key RAM
* \param keys Pointer to AES Keys
* \param key_size Key size: \c AES_KEY_STORE_SIZE_KEY_SIZE_x
* \param count Number of keys (1 to 8 - \p start_area for 128-bit keys, 1 to
* (8 - \p start_area) / 2 for 192- and 256-bit keys)
* \param start_area Start area in Key RAM where to store the key (0 to 7, must
* be even for 192- and 256-bit keys)
* \return \c CRYPTO_SUCCESS if successful, or CRYPTO/AES error code
* \note Calling this function with a value of \p key_size different from the
* one passed for the previous calls causes the deletion of all previously
* stored keys.
