Pixelbuf doc fix

ujson: do not eat trailing whitespace

2020-05-11T03:45:42+00:00

Ujson should only worry about whitespace before JSON. This becomes apparent when you are using MP stream protocol to read directly from input buffers. When you attempt to read(1) on a UART (and possibly other protocols) you have to wait for either the byte or the timeout. Fixes: - Waiting for a timeout after you have completed reading a correct and complete JSON off the input. - Raising an OSError after reading a correct and complete JSON off the input. - Eating more data than semantically owned off the input buffer. - Blocking to start parsing JSON until the entire JSON body has been loaded into a potentially large, contiguous Python object. Code you would write before: ``` line = board_busio_uart_port.read_line() json_dict = json.loads(line) ``` or reaching for fixed buffers and swapping them around in Python. Code that did not work before that does now: ``` json_dict = json.load(board_busio_uart_port) ``` - This removes the need for intermediate copies of data when reading JSON from micropython stream protocol inputs. - It also increases total application speed by parsing JSON concurrently with receiving on boards that read from UART via DMA. - It simplifies code that users write while improving their apps.

aesio: add basic AES encryption and decryption

2020-05-06T09:40:06+00:00

This adds initial support for an AES module named aesio. This implementation supports only a subset of AES modes, namely ECB, CBC, and CTR modes. Example usage: ``` >>> import aesio >>> >>> key = b'Sixteen byte key' >>> cipher = aesio.AES(key, aesio.MODE_ECB) >>> output = bytearray(16) >>> cipher.encrypt_into(b'Circuit Python!!', output) >>> output bytearray(b'E\x14\x85\x18\x9a\x9c\r\x95>\xa7kV\xa2`\x8b\n') >>> ``` This key is 16-bytes, so it uses AES128. If your key is 24- or 32- bytes long, it will switch to AES192 or AES256 respectively. This has been tested with many of the official NIST test vectors, such as those used in `pycryptodome` at https://github.com/Legrandin/pycryptodome/tree/39626a5b01ce5c1cf51d022be166ad0aea722177/lib/Crypto/SelfTest/Cipher/test_vectors/AES CTR has not been tested as NIST does not provide test vectors for it.
