Installation

To install the Crittora SDK, you need to have Composer installed. Run the following command to install the dependencies:

composer require wutif/crittora-sdk-php

Demo Application

The simplest way to get started with Crittora is to view a demo. The demo application provides a simple interface to test the authentication, encryption, and decryption functionalities of the SDK.

Features

• User authentication using environment variables.
• Data encryption and decryption.
• User-friendly web interface built with Bootstrap.

Requirements

• PHP 7.2 or higher
• Composer
• Access to the Crittora SDK

Usage

Initialize SDK

Initialize the SDK by passing in your accessKey and secretKey. This will return the IdToken which you will need to use when calling the encrypt and decrypt methods

use Crittora\CrittoraSDK;

$sdk = new CrittoraSDK($accessKey, $secretKey);

Example

try {
    $sdk = new CrittoraSDK($accessKey, $secretKey);
    $authResponse = $sdk->authenticate($username, $password);
    echo json_encode(['success' => true, 'IdToken' => $authResponse['IdToken']]);
} catch (Exception $e) {
    http_response_code(401);
    echo json_encode(['success' => false, 'error' => $e->getMessage()]);
}

Authentication

To authenticate a user, use the authenticate method of the CrittoraSDK class. This method requires a username and password and returns an array containing tokens.

$authResponse = $sdk->authenticate('username', 'password');

Encryption

To encrypt data, use the encrypt method. This method requires an ID token, the data to encrypt, and an optional array of permissions.

$encryptedData = $sdk->encrypt($idToken, 'data to encrypt', ['read', 'write']);

Decryption

To decrypt data, use the decrypt method. This method requires an ID token, the encrypted data, and an optional array of permissions.

$decryptedData = $sdk->decrypt($idToken, $encryptedData, ['read']);

Testing

To run the tests, use PHPUnit. Ensure you have PHPUnit installed and configured. Run the following command in the root directory:

  vendor/bin/phpunit
