README

A PHP package for customizable Base64 encoding and decoding with support for custom character sets and optional reversed output.

Features

• Customizable Base64 character sets.
• Optional reversed output for encoding/decoding.

Requirements

PHP 8+

Installation

1. Use the library via Composer:

composer require edgaras/custombase64

1. Include the Composer autoloader:

require __DIR__ . '/vendor/autoload.php';

Usage

1. Initialization

You can initialize the CustomBase64 class with optional parameters:

use Edgaras\CustomBase64\CustomBase64;

// Default initialization
$base64 = new CustomBase64();

// Custom charset and reversed output
$customChars = 'TPUQVRWXSYZABCDENOFGHIJKLMnopqrstuvwxyzabcdefghijklm0123456789+-';
$reverseOutput = true;
$base64 = new CustomBase64($customChars, $reverseOutput);

2. Encoding data

Use the encode method to convert data into custom Base64 format:

$data = "Hello, CustomBase64!";
$encoded = $base64->encode($data);
echo "Encoded: " . $encoded;
// Example output: "=VUC2H2puYHoiO3p1CVSf8WofIWF"

3. Decoding Data

Decode Base64-encoded strings back to their original form using the decode method:

$encoded = "=VUC2H2puYHoiO3p1CVSf8WofIWF";
$decoded = $base64->decode($encoded);
echo "Decoded: " . $decoded;
// Example output: "Hello, CustomBase64!"
