\brief AES-CTR buffer encryption/decryption

Warning: You have to keep the maximum use of your counter in mind!

Note: Due to the nature of CTR you should use the same key schedule for both encryption and decryption. So a context initialized with esp_aes_setkey_enc() for both AES_ENCRYPT and AES_DECRYPT.

\param ctx AES context \param length The length of the data \param nc_off The offset in the current stream_block (for resuming within current cipher stream). The offset pointer to should be 0 at the start of a stream. \param nonce_counter The 128-bit nonce and counter. \param stream_block The saved stream-block for resuming. Is overwritten by the function. \param input The input data stream \param output The output data stream

\return 0 if successful
