twisted.python.randbytes.RandomFactory

class documentation

class RandomFactory: (source)

Factory providing secureRandom and insecureRandom methods.

You shouldn't have to instantiate this class, use the module level functions instead: it is an implementation detail and could be removed or changed arbitrarily.

Method	`insecureRandom`	Return a number of non secure random bytes.
Method	`secureRandom`	Return a number of secure random bytes.
Class Variable	`randomSources`	Undocumented
Method	`_osUrandom`	Wrapper around `os.urandom` that cleanly manage its absence.
Method	`_randBits`	Wrapper around `os.getrandbits`.
Method	`_randModule`	Wrapper around the `random` module.
Constant	`_BYTES`	Undocumented

def insecureRandom(self, nbytes: int) -> bytes: (source) ¶

Return a number of non secure random bytes.

Parameters
nbytes:`int`	number of bytes to generate.

Returns
`str`	a string of random bytes.

def secureRandom(self, nbytes: int, fallback: bool = False) -> bytes: (source) ¶

Return a number of secure random bytes.

Parameters
nbytes:`int`	number of bytes to generate.
fallback:`bool`	Whether the function should fallback on non-secure random or not. Default to `False`.

Returns
`str`	a string of random bytes.

randomSources: tuple = (source) ¶

Undocumented

def _osUrandom(self, nbytes: int) -> bytes: (source) ¶

def _randBits(self, nbytes: int) -> bytes: (source) ¶

Wrapper around os.getrandbits.

def _randModule(self, nbytes: int) -> bytes: (source) ¶

Wrapper around the random module.

_BYTES = (source) ¶

Undocumented
