secure-random
A simple JavaScript component to normalize the creation of cryptographically strong random values.
Why?
Context switching between the browser and Node.js and creating cryptographically secure random numbers is annoying. This normalizes the behavior. Used by CryptoCoinJS and BitcoinJS.
Install
Node.js/Browserify
npm install --save secure-random
Component
component install jprichardson/secure-random
Bower
bower install secure-random
Script
Usage
secureRandom(byteCount, options)
- byteCount: is the number of bytes to return.
- options: options to pass. Only valid value at this time
type
.type
can be eitherArray
,Uint8Array
, orBuffer
.Buffer
is only valid in Node.js or Browserify environments - it will throw an error otherwise.
return an Array
:
var bytes = //return an Array of 10 bytesconsole //10
or:
var bytes = //return an Array of 10 bytesconsole //10
return a Buffer
:
var bytes = //return a Buffer of 10 bytesconsole //10
return a Uint8Array
:
var bytes = //return a Uint8Array of 10 bytesconsole //10
randomArray(byteCount)
Sugar for secureRandom(byteCount, {type: 'Array'})
.
var secureRandom = var data = secureRandom
randomUint8Array(byteCount)
Sugar for secureRandom(byteCount, {type: 'Uint8Array'})
.
var secureRandom = var data = secureRandom
randomBuffer(byteCount)
Sugar for secureRandom(byteCount, {type: 'Buffer'})
.
var secureRandom = var data = secureRandom
Handling Errors
An error will be thrown if a secure random number generator is not available.
throw "Your browser does not support window.crypto."
