t.p.r.RandomFactory(object) : class documentation

Part of twisted.python.randbytes View Source View In Hierarchy

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	secureRandom	Return a number of secure random bytes.
Method	insecureRandom	Return a number of non secure random bytes.
Method	_osUrandom	Wrapper around `os.urandom` that cleanly manage its absence.
Method	_randBits	Wrapper around `os.getrandbits`.
Method	_randRange	Wrapper around `random.randrange`.

def _osUrandom(self, nbytes): (source)

Wrapper around os.urandom that cleanly manage its absence.

def secureRandom(self, nbytes, fallback=False): (source)

Return a number of secure random bytes.

Parameters	nbytes	number of bytes to generate. (type: `int`)
	fallback	Whether the function should fallback on non-secure random or not. Default to `False`. (type: `bool`)
Returns	a string of random bytes. (type: `str`)

def _randBits(self, nbytes): (source)

Wrapper around os.getrandbits.

def _randRange(self, nbytes): (source)

Wrapper around random.randrange.

def insecureRandom(self, nbytes): (source)

Return a number of non secure random bytes.

Parameters	nbytes	number of bytes to generate. (type: `int`)
Returns	a string of random bytes. (type: `str`)
