suspect-devices/circuitpython/py/circuitpy_defns.mk, branch 5.4.0-beta.0CircuitPython - a Python implementation for teaching coding with microcontrollershttps://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=5.4.0-beta.02020-05-06T09:40:06+00:00aesio: add basic AES encryption and decryption2020-05-06T09:40:06+00:00Sean Crosssean@xobs.io2020-04-14T03:18:45+00:00urn:sha1:b168784fa0fd97b17807836b390c79abaadfa8e4
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.

This isn't perfect and needs a bit more testing.
RGBMatrix: finish renaming from Protomatter2020-04-17T23:44:07+00:00Jeff Eplerjepler@gmail.com2020-04-15T20:01:24+00:00urn:sha1:5fcc6d62869310b2b1dd96279e5a121623e07aba
This gets all the purely internal references. Some uses of
protomatter/Protomatter/PROTOMATTER remain, as they are references
to symbols in the Protomatter C library itself.

This is a quick rename, it changes the user-facing names but not the
internal names of things.

I originally believed that there would be a wrapper library around it,
like with _pixelbuf; but this proves not to be the case, as there's
too little for the library to do.
