FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package crypt
Lithe Crypt
Lithe Crypt is a simple encryption and decryption utility for PHP, designed to work with the Lithe framework. It utilizes the AES-256-CBC algorithm for secure data handling.
Installation
To install the Lithe Crypt package, you can use Composer. If you haven't already, make sure you have Composer installed. Then run the following command in your project directory:
Requirements
- PHP 8 or higher
- OpenSSL extension enabled in your PHP installation
Usage
Loading Environment Variables
Before using the Crypt class, you need to load your environment variables. Use the following code to load your .env file:
Setting the APP_KEY
Ensure that the APP_KEY environment variable is set. This key should be a base64 encoded string of 32 bytes. You can configure it in your .env file or directly in your server environment.
Example of a valid base64 key:
Encrypting Data
To encrypt data, use the encrypt method of the Crypt class. You can also specify whether you want to use a fixed IV (initialization vector) for encryption:
Decrypting Data
To decrypt the previously encrypted data, use the decrypt method. You must specify the same parameters used during encryption to ensure proper decryption:
Exception Handling
If the APP_KEY is not set or is invalid, the Crypt class will throw a CryptException. It's essential to handle this exception in your code to avoid unexpected errors:
Unit Tests
To ensure the functionality of the Crypt class, unit tests are provided. You can run the tests using PHPUnit:
Test Cases
testEncryptDecrypt: Tests the encryption and decryption process.testEncryptWithNullData: Tests encryption with null data.testEncryptWithSameIV: Tests the behavior of encryption with a fixed IV.
