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.

This isn't perfect and needs a bit more testing.
