hbutils.random.binary.random_bytes(length: int = 32, allow_zero: bool = False, rnd: Optional[random.Random] = None) → bytes[source]¶

Overview:

Generate random bytes.

Arguments:

length (int): Length of bytes, default is 32.
allow_zero (bool): Allow 0x00 appear in the result, default is False.
rnd (Optional[random.Random]): Random object you used,
default is None which means just use the default one provided by system.

Returns:

bytes (bytes): Random bytes.

Examples::

>>> from hbutils.random import random_bytes
>>> random_bytes()
