===================

[](#semperton-multibase)

Base transcoder with multibyte character alphabet support.

---

Installation
------------

[](#installation)

Just use Composer:

```
composer require semperton/multibase

```

Multibase requires PHP 7.4+ and the mbstring extension

> Tip: Install the GMP extension for faster base conversion up to base 62

Package
-------

[](#package)

Included base transcoders:

- Base58
- Base62
- Base85 RFC 1924

Usage
-----

[](#usage)

Multibase transcoders are able to convert any arbitrary data. Use them as URL / MD5 shorteners, password generators, Base64 alternatives...

```
use Semperton\Multibase\Base62;
use Semperton\Multibase\Base85;

// basic usage
$base62 = new Base62();
$base62->encode('Hello World'); // 73XpUgyMwkGr29M
$base62->decode('73XpUgyMwkGr29M'); // Hello World

// shorten md5 hash
$hash = md5('Hello World'); // b10a8db164e0754105b7a99be72e3fe5

$short = $base62->encode(hex2bin($hash)); // 5O4SoozqXEOwlYtvkC5zkr
$short = $base62->encode(md5('Hello World', true)); // same as above

$decoded = $base62->decode($short);
$hash === bin2hex($decoded); // true

// password generation
$bytes = openssl_random_pseudo_bytes(16);
$password = (new Base85())->encode($bytes); // e.g. Ncg>RWSYO+2t@~G8PO0J
```

Custom transcoders
------------------

[](#custom-transcoders)

You can create custom transcoders with your own alphabets (multibyte support). Just for fun, how about an emoji transcoder?

```
use Semperton\Multibase\Transcoder\BaseTranscoder;

$emojiTranscoder = new BaseTranscoder(
	'🧳🌂☂️🧵🪡🪢🧶👓🕶🥽🥼🦺👔👕👖🧣🧤🧥🧦👗👘🥻🩴🩱🩲' .
	'🩳👙👚👛👜👝🎒👞👟🥾🥿👠👡🩰👢👑👒🎩🎓🧢⛑🪖💄💍💼'
);

$encoded = $emojiTranscoder->encode('Hello World'); // ☂🪢👟🩴🩰🥻👚👙🧢🩲🧥🥽🎩👙👝🎒
$emojiTranscoder->decode($encoded); // Hello World
```
