Introduction
------------

[](#introduction)

When using QR or Aztec codes a different encoding scheme is needed than the already established base 64, base 32 and base 16 encoding schemes that are described in RFC [RFC4648](https://datatracker.ietf.org/doc/html/rfc4648). The difference from those and base 45 is the key table and that the padding with '=' is not required.

Install
-------

[](#install)

Install with [composer](https://getcomposer.org/).

```
$ composer require mhauri/base45
```

Usage
-----

[](#usage)

```
$base45 = new \Mhauri\Base45();

$encoded = $base45->encode(random_bytes(128));
$decoded = $base45->decode($encoded);
```

Testing
-------

[](#testing)
