Can be used as a plain script, a node.js module or an AMD module.
|
||||
|
||||
Script tag usage
|
||||
----------------
|
||||
|
||||
<script src=//cdnjs.cloudflare.com/ajax/libs/seedrandom/2.3.6/seedrandom.min.js>
|
||||
</script>
|
||||
|
||||
// Sets Math.random to a PRNG initialized using the given explicit seed.
|
||||
Math.seedrandom('hello.');
|
||||
console.log(Math.random()); // Always 0.9282578795792454
|
||||
console.log(Math.random()); // Always 0.3752569768646784
|
||||
|
||||
// Sets Math.random to an ARC4-based PRNG that is autoseeded using the
|
||||
// current time, dom state, and other accumulated local entropy.
|
||||
// The generated seed string is returned.
|
||||
Math.seedrandom();
|
||||
console.log(Math.random()); // Reasonably unpredictable.
|
||||
|
||||
// Seeds using the given explicit seed mixed with accumulated entropy.
|
||||
Math.seedrandom('added entropy.', { entropy: true });
|
||||
console.log(Math.random()); // As unpredictable as added entropy.
|

|

// Use "new" to create a local prng without altering Math.random.
|

var myrng = new Math.seedrandom('hello.');
|

console.log(myrng()); // Always 0.9282578795792454
|
||||
|

|
||||
Node.js usage
|
||||
-------------
|
||||
|

npm install seedrandom
|
||||
|
||||
// Local PRNG: does not affect Math.random.
|
||||
var seedrandom = require('seedrandom');
|
||||
var rng = seedrandom('hello.');
|
||||
console.log(rng()); // Always 0.9282578795792454
|
||||
|

// Autoseeded ARC4-based PRNG.
|

// Mixing accumulated entropy.

|

|

|
||||
Require.js usage
|
||||
----------------
|
||||
|
||||
Similar to node.js usage:
|
||||
|
||||
bower install seedrandom
|
||||
|
||||
require(['seedrandom'], function(seedrandom) {
|
||||
var rng = seedrandom('hello.');
|
||||
console.log(rng()); // Always 0.9282578795792454
|
||||
});
|
||||
|
||||
|
||||
Network seeding via a script tag
|
||||
--------------------------------
|
||||
|
||||
<script src=//cdnjs.cloudflare.com/ajax/libs/seedrandom/2.3.6/seedrandom.min.js>
|
||||
</script>
|
||||
<!-- Seeds using urandom bits from a server. -->
|
||||
<script src=//jsonlib.appspot.com/urandom?callback=Math.seedrandom">
|
||||
</script>
|
||||
|
||||
Examples of manipulating the seed for various purposes:
|
||||
|
||||
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 < 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 };
|
||||
}});
|
||||
|
||||
|
||||
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.
|
||||
|
||||
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().
