SixChars ========

SixChars

SixChars is light-weight code that generates a random looking string that represents a number (between 0 and 1,073,741,823).

It is useful for things like referral links or invite codes.

For example, you can embed a referrer's userid like this:
http://example.com/welcome/LK8HBY

** This is NOT for secure encryption! **

var key = "WLZFX9KSEJG8647AHM5CQB3TPVY20RND";
var sixchars = require("./sixchars")(key);
 
console.log(sixchars.generate(1));
// LK8HBY 
 
console.log(sixchars.parse("LK8HBY"));
// 1 

...thats pretty much all there is.

You need to provide the SixChars constructor a 32 unique character key.

Don't feel like crafting the key yourself? Here- run this:

var chars = '023456789ABCDEFGHJKLMNPQRSTVWXYZ';
 
var a = chars.split('');
 
//credit for randomizer goes to: http://stackoverflow.com/a/3943985 
var n = a.length;
 
for(var i = n - 1; i > 0; i--) {
    var j = Math.floor(Math.random() * (+ 1));
    var tmp = a[i];
    a[i] = a[j];
    a[j] = tmp;
}
console.log(a.join(''));
