Colu-node

Colu platform, PHP SDK

Install

Install Composer in your project:

    $curl -s http://getcomposer.org/installer | php

Create a composer.json file in your project root:

    {
        "require": {
            "Colu/Colu": "1.0.4"
        }
    }

Install via Composer

    $php composer.phar install

Generate keys for your company:

If you create an instance of the Colu class with only the company name, the privateKey will be generated randomly on your machine. Your privateKey is what defines your company.

require_once ('vendor/autoload.php');
use Colu\ColuSDK\Colu;
$colu = new Colu('my_company', 'testnet');

// This is your private key, keep it safe!!!
echo 'WIF: '.$colu->getWIF();

Create instance from an existing key:

When you want to use our module in your server you need to generate keys only once. After that you can create an instance of Colu with your key:

require_once ('vendor/autoload.php');
use Colu\ColuSDK\Colu;

$privateKey = 'cQQy71GeXGeFWnDtypas2roY2qrk3KWjJLCxoFqc2wibXr2wWxie'; // this is the WIF version of a private key

$colu = new Colu('my_company', 'testnet', $privateKey);

Register a user using 2FA:

There are two methods for registering a user using 2FA, directly by using a Phonenumber or by generating a QR code and then having the user scan the QR with their phone.

In both methods you need to Create a registration message:

$username = 'bob';
$registrationMessage = $colu->createRegistrationMessage($username);

1. QR registration:

$qr = $colu->createRegistrationQR($registrationMessage);

This will return an array containing the QR and the message to be verified:

  "qr" => $qrCode->getDataUri (), // this is the actual QR image
  "code" => $qrRegCode, // send this to the registerUserByCode function
  "message" => $message // send this to the registerUserByCode function 

Send the registration request:

$colu->registerUserByCode ( $code, $message );

This will send a push notification to the user mobile application that will wait until approval is recieved.

2. Phonenumber Registration:

$phonenumber = "+12323455673";
$colu->registerUserByPhonenumber ( $phonenumber, $registrationMessage );

This will send a push notification to the user mobile application that will wait until approval is recieved.

If successful both cases return an array:

"success" => true,
"userId" => $user->getId () // this is the user ID

save the userId for future verifications.

Verify user:

To verify a user:

$username = 'bob';
$userId = 'tpubDCgCu2jpxrR7j9JwFQ959wSkNwPQFNQvJJMFnikg1Sb4tkDnBNYaS3Sc1BxKL71hk3jPkQStEY1VE9mTaQjF8kDfEhzxjWid7eVK5F7nWi5';

if ($colu->verifyUser($username, $userId, 0)) {
    echo "verified";
  }
  else {
    echo $colu->error;
    // something bad happened
  }
}

This will send a push to the user mobile application and prompt him to sign on your message, you will receive the user signature and verify it locally.
