base32

Base32 Encoder/Decoder for PHP according to RFC 4648.

Do you like this? Flattr it:

Usage

<?php

// Include class or user autoloader
use Base32\Base32;

$string = 'fooba';

$encoded = Base32::encode($string);
// $encoded contains now 'MZXW6YTB'

$decoded = Base32::decode($encoded);
// $decoded is again 'fooba'

About

Use

Initially created to work with the one time password project, yet it can stand alone just as well as Jordi Boggiano kindly pointed out. It's the only Base32 implementation I could make work that passes the test vectors (and contains unit tests).

Goal

Have a RFC compliant Base32 encoder and decoder. The implementation could be improved, but for now, it does the job and has unit tests. Ideally, the class can be enhanced while the unit tests keep passing.

Requirements

PHP 5.3 to 5.6 or 7.0+

If you want to run the tests, PHPUnit 5.0+ or up is required. Tests require PHP 5.6 or 7.0+.
