README

A simple PHP library to assist with passing a DVC (Domain Verification Check) check by Comodo. It uses a API Endpoint documented here to get the MD5 & SHA1 hashes. It can then check that these are installed on a domain by requesting http://yourdomain.com/(MD5Hash).txt.

For more infomation about Domain Control Validation read this

Installation

Installation is done via composer: composer require xigen/comodo-decode-csr

Requirements

Below is a list of requirements. There are unit tests to check compatibility with the diffrent PHP versions.

• PHP 5.5+ (Tested 5.5, 5.6, 7 & HHVM)
• Guzzle 6.X
• The php-curl extension

Example Usage

This will use the test CSR within the repo and get the MD5 and SHA1 hashes. Then it will check that the text file is installed correctly.

require 'vendor/autoload.php';

$ComodoDecodeCSR = new ComodoDecodeCSR();

//Get the csr from a file as a string or could just use a string
$csr = file_get_contents('certificate/test.csr');
$ComodoDecodeCSR->setCSR($csr);

$Hashes = $ComodoDecodeCSR->fetchHashes();
$Check = $ComodoDecodeCSR->checkInstalled();
var_dump($Hashes, $Check);
/*
array(2) {
  'md5' =>
  string(32) "98EB197EF83F7A9EB736ED7CEBD413CE"
  'sha1' =>
  string(40) "DA9C72B6F6BCB05772BF8543E19D1A41B0210E84"
}
bool(true)
*/

Console Application

There is also a console application to quickly test a domain. To use it you will need to install this globaly via composer:

composer global require xigen/comodo-decode-csr

Now the command ComodoDecodeCSR should be avalible (if not check you path includes ~/.composer/vendor/bin/). You can now check if a domain will pass the DVC like so:

➜ ComodoDecodeCSR check certificate.csr
Success!
This domain should pass DVC
