base64.js

Yet another Base64 transcoder

Usage

In Browser

<script src="base64.js"></script>

node.js

var Base64 = require('./combinatorics.js').Base64;

SYNOPSIS

Base64.encode('dankogai');  // ZGFua29nYWk=
Base64.encode('小飼弾');    // 5bCP6aO85by+
Base64.encodeURI('小飼弾'); // 5bCP6aO85by-

Base64.decode('ZGFua29nYWk=');  // dankogai
Base64.decode('5bCP6aO85by+');  // 小飼弾
// note .decodeURI() is unnecessary since it accepts both flavors
Base64.decode('5bCP6aO85by-');  // 小飼弾

String Extension for ES5

if (Base64.extendString) {
    // you have to explicitly extend String.prototype
    Base64.extendString();
    // once extended, you can do the following
    'dankogai'.toBase64();       // ZGFua29nYWk=
    '小飼弾'.toBase64();         // 5bCP6aO85by+
    '小飼弾'.toBase64(true);     // 5bCP6aO85by-
    '小飼弾'.toBase64URI();      // 5bCP6aO85by-
    'ZGFua29nYWk='.fromBase64(); // dankogai
    '5bCP6aO85by+'.fromBase64(); // 小飼弾
    '5bCP6aO85by-'.fromBase64(); // 小飼弾
}
