slowdown.token – The python token implementation¶
Example:
>>> tokenizer = \
... AES_RC4(
... aes_key=Crypto.Random.get_random_bytes(16), # 16 Bytes
... rc4_key=Crypto.Random.get_random_bytes(8), # 8 Bytes
...
... # The decryption of tokens can speed up by caching.
... # The default `cache_size` is 256.
... cache_size=256,
...
... # Tokens shoud be limited to a maximum length
... # to avoid attacks on man-made tokens.
... # The default `max_token` is 1048.
... max_token=1048
... )
>>> token = \
... tokenizer.pack(
... {
'expiration_time': time.time()+3600,
... 'username': 'guest'
... }
... )
>>> tokenizer.unpack(token)
{'expiration_time': 1600000000.0, 'username': 'guest'}

class
slowdown.token.AES_RC4(aes_key: bytes = None, rc4_key: bytes = None, cache_size: int = - 1, max_token: int = - 1, magic_bytes: str = None)¶ The token encrypted by both AES and ARC4 algorithms.
-
pack(data: object) → str¶ Generate a encrypted token from the marshalable data.
-
unpack(token: str) → object¶ Validate the token and return the data contained in the encrypted token string.
