* \brief This function performs an ARIA single-block encryption or
* decryption operation.
*
- * It performs the operation defined in the \p mode parameter
- * (encrypt or decrypt), on the input data buffer defined in
- * the \p input parameter.
+ * It performs encryption or decryption (depending on whether
+ * the key was set for encryption on decryption) on the input
+ * data buffer defined in the \p input parameter.
*
* mbedtls_aria_init(), and either mbedtls_aria_setkey_enc() or
* mbedtls_aria_setkey_dec() must be called before the first
* call to this API with the same context.
*
* \param ctx The ARIA context to use for encryption or decryption.
- * \param mode The ARIA operation: #MBEDTLS_ARIA_ENCRYPT or
- * #MBEDTLS_ARIA_DECRYPT.
* \param input The 16-Byte buffer holding the input data.
* \param output The 16-Byte buffer holding the output data.
* \return \c 0 on success.
