bpo-40465: Deprecate the optional argument to random.shuffle(). (#19867) 2020-05-02 16:45:32 -07:00
Raymond Hettinger d3a8d616fa
Small improvements to the recipes and examples. (GH-19635) 
* Add underscores to long numbers to improve readability
* Use bigger dataset in the bootstrapping example
* Convert single-server queue example to more useful multi-server queue

bpo-40282: Allow random.getrandbits(0) (GH-19539) 2020-04-17 19:32:14 +02:00
Victor Stinner 9f5fe7910f
bpo-40286: Add randbytes() method to random.Random (GH-19527) 
Add random.randbytes() function and random.Random.randbytes()
method to generate random bytes.

Modify secrets.token_bytes() to use SystemRandom.randbytes()
rather than calling directly os.urandom().

Rename also genrand_int32() to genrand_uint32(), since it returns an
unsigned 32-bit integer, not a signed integer.

The _random module is now built with Py_BUILD_CORE_MODULE defined.

Raymond Hettinger c89a451ae1 By popular demand, add back a security warning. 2014-05-11 02:26:23 -07:00
Raymond Hettinger a7894f7f4c Remove the redundant and poorly worded warning message. 
The paragraph above already says, clearly and correctly, that
"However, being completely deterministic, it is not suitable for
all purposes, and is completely unsuitable for cryptographic purposes."

Also we should make any promises about SystemRandom or os.urandom()
being cryptographically secure (they may be, but be can't validate
that promise).  Further, those are actual random number generators
not psuedo-random number generators.
