### Basic Usage of Encoding Functions

Source: https://github.com/paragonie/constant_time_encoding/blob/master/README.md

Demonstrates how to use the main Encoding class to perform Base64, Base32, and Hex encoding on random bytes. It shows the output for different encoding variants.

```php
use ParagonIE\ConstantTime\Encoding;

// possibly (if applicable): 
// require 'vendor/autoload.php';

$data = random_bytes(32);
echo Encoding::base64Encode($data), "\n";
echo Encoding::base32EncodeUpper($data), "\n";
echo Encoding::base32Encode($data), "\n";
echo Encoding::hexEncode($data), "\n";
echo Encoding::hexEncodeUpper($data), "\n";
```

### Specific Encoding Class Usage

Source: https://github.com/paragonie/constant_time_encoding/blob/master/README.md

Shows how to use individual encoding classes like Base64 and Base32 directly for encoding operations.

```php
use ParagonIE\ConstantTime\Base64;
use ParagonIE\ConstantTime\Base32;

$data = random_bytes(32);
echo Base64::encode($data), "\n";
echo Base32::encode($data), "\n";
```
