=============
Seeded random number generator for Javascript.

Network seeding
---------------

</script>
<!-- Seeds using urandom bits from a server. -->
<script src=//jsonlib.appspot.com/urandom?callback=Math.seedrandom">

<script>
(function(x, u, s){
try {
// Make a synchronous request to random.org.
x.open('GET', u, false);
x.send();
s = unescape(x.response.trim().replace(/^|\s/g, '%'));
} finally {
// Seed with the response, or autoseed on failure.
Math.seedrandom(s, !!s);
}
})(new XMLHttpRequest, 'https://www.random.org/integers/' +
'?num=256&min=0&max=255&col=1&base=16&format=plain&rnd=new');
</script>
Reseeding using user input
--------------------------
var seed = Math.seedrandom(); // Use prng with an automatic seed.
document.write(Math.random()); // Pretty much unpredictable x.
var rng = new Math.seedrandom(seed); // A new prng with the same seed.
document.write(rng()); // Repeat the 'unpredictable' x.
function reseed(event, count) { // Define a custom entropy collector.
var t = [];
function w(e) {
t.push([e.pageX, e.pageY, +new Date]);
if (t.length &lt; count) { return; }
document.removeEventListener(event, w);
Math.seedrandom(t, { entropy: true });
}
document.addEventListener(event, w);
}
reseed('mousemove', 100); // Reseed after 100 mouse moves.
The "pass" option can be used to get both the prng and the seed.
The following returns both an autoseeded prng and the seed as an object,
without mutating Math.random:
var obj = Math.seedrandom(null, { pass: function(prng, seed) {
return { random: prng, seed: seed };
}});
Saving and Restoring PRNG state
-------------------------------
var seedrandom = Math.seedrandom;
var saveable = seedrandom("secret-seed", {state: true});
for (var j = 0; j < 1e5; ++j) saveable();
var saved = saveable.state();
var replica = seedrandom("", {state: saved});
assert(replica() == saveable());
In normal use the prng is opaque and its internal state cannot be accessed.
However, if the "state" option is specified, the prng gets a state() method
that returns a plain object the can be used to reconstruct a prng later in
the same state (by passing that saved object back as the state option).
Version notes
-------------
The random number sequence is the same as version 1.0 for string seeds.
* Version 2.0 changed the sequence for non-string seeds.
* Version 2.1 speeds seeding and uses window.crypto to autoseed if present.
* Version 2.2 alters non-crypto autoseeding to sweep up entropy from plugins.
* Version 2.3 adds support for "new", module loading, and a null seed arg.
* Version 2.3.1 adds a build environment, module packaging, and tests.
* Version 2.3.4 fixes bugs on IE8, and switches to MIT license.
* Version 2.3.6 adds a readable options object argument.
* Version 2.3.10 adds support for node.js crypto (contributed by ctd1500).
* Version 2.3.11 adds an option to load and save internal state.
The standard ARC4 key scheduler cycles short keys, which means that
seedrandom('ab') is equivalent to seedrandom('abab') and 'ababab'.
Therefore it is a good idea to add a terminator to avoid trivial
equivalences on short string seeds, e.g., Math.seedrandom(str + '\0').
Starting with version 2.0, a terminator is added automatically for
non-string seeds, so seeding with the number 111 is the same as seeding
with '111\0'.
When seedrandom() is called with zero args or a null seed, it uses a
seed drawn from the browser crypto object if present. If there is no
crypto support, seedrandom() uses the current time, the native rng,
and a walk of several DOM objects to collect a few bits of entropy.
Each time the one- or two-argument forms of seedrandom are called,
entropy from the passed seed is accumulated in a pool to help generate
future seeds for the zero- and two-argument forms of seedrandom.
On speed - This javascript implementation of Math.random() is several
times slower than the built-in Math.random() because it is not native
code, but that is typically fast enough. Some details (timings on
Chrome 25 on a 2010 vintage macbook):
* seeded Math.random() - avg less than 0.0002 milliseconds per call
* seedrandom('explicit.') - avg less than 0.2 milliseconds per call
* seedrandom('explicit.', true) - avg less than 0.2 milliseconds per call
* seedrandom() with crypto - avg less than 0.2 milliseconds per call
Autoseeding without crypto is somewhat slower, about 20-30 milliseconds on
a 2012 windows 7 1.5ghz i5 laptop, as seen on Firefox 19, IE 10, and Opera.
Seeded rng calls themselves are fast across these browsers, with slowest
numbers on Opera at about 0.0005 ms per seeded Math.random().
