README

A PHP library that generates camouflaged URLs for usage with camo or go-camo TLS image proxy.

Installation

Just run

$ composer require jdreesen/camo-url-generator

Example

use Dreesen\Image\HexCamo;
use Dreesen\Image\HttpOnlyCamo;

$camo = new HttpOnlyCamo(new HexCamo('https://img.example.org', 'secret'));

echo $camo->camouflage('http://example.org/image.jpg');

The secret is the same HMAC key you used on your camo server instance running on https://img.example.org.

What's inside?

• Dreesen\Image\Camo: Interface for your type-hinting which is implemented by all the following classes.
• Dreesen\Image\HexCamo: Generates URLs for usage with the camo or go-camo image proxy in HEX format.
• Dreesen\Image\Base64Camo: Generates URLs for usage with the go-camo image proxy in Base64 format.
• Dreesen\Image\QueryStringCamo: Generates URLs for usage with the camo image proxy in query string format.
• Dreesen\Image\HttpOnlyCamo: Decorator to only camouflage HTTP (non-secure) URLs.
• Dreesen\Image\NoCamo: Disables image camouflage by returning given URLs as they are.
