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 stategies, sizes are measured in blocks and + * that an ARIA 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 ARIA context to use for encryption or decryption. + * This must be initialized and bound to a key. + * \param length The length of the input data \p input in Bytes. + * \param nc_off The offset in Bytes in the current \p stream_block, + * for resuming within the current cipher stream. The + * offset pointer should be \c 0 at the start of a + * stream. This must not be larger than \c 15 Bytes. + * \param nonce_counter The 128-bit nonce and counter. This must point to + * a read/write buffer of length \c 16 bytes. + * \param stream_block The saved stream block for resuming. This must + * point to a read/write buffer of length \c 16 bytes. + * This is overwritten by the function. + * \param input The buffer holding the input data. This must + * be a readable buffer of length \p length Bytes. + * \param output The buffer holding the output data.
