FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

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 PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • 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 encryption

Encryption Package

The Encryption package is a simple Composer package that provides functionality for encrypting and decrypting data using the Defuse PHP encryption library. This package simplifies the process of handling encryption keys and allows you to perform encryption and decryption operations on files and data with ease.

Installation

To use this package in your PHP application, you need to have Composer installed. Once you have Composer set up, run the following command to add the package to your project:

Usage

Encryption Key Generation

To encrypt and decrypt data using the library, you need to generate an encryption key. The EncryptionKey class provides a simple way to generate a new random encryption key in ASCII format:

Ensure you keep the generated encryption key secure and protected, as it is essential for encrypting and decrypting sensitive data.

Setting up Encryption

To use the Encryption package, you first need to set up the Encryption class by providing the necessary parameters:

Encrypting and Decrypting Files

You can use the encrypt_file() and decrypt_file() methods to encrypt and decrypt files:

Encrypting Data

You can use the encrypt() method to encrypt data, such as sensitive information:

Decrypting Data

To decrypt encrypted data, use the decrypt() method:

Encrypting .env File

The package provides a method to encrypt the contents of a .env file:

The encrypted contents will be saved in a file named .env.encrypted.

Key Management

The Encryption class expects the secret key file to be stored in ASCII format. It retrieves the encryption key from the secret key file specified during initialization. Make sure to keep the secret key file secure and protected.

If you have a constant WEBAPP_ENCRYPTION_KEY defined, the class will use that as the encryption key. Otherwise, it will look for the secret key file in the provided directory with the default filename identifier 'secret'. The key file should be named as '.secret.txt' by default unless you specify a different key filename identifier during initialization.

License

This package is open-source software licensed under the MIT License.

Acknowledgments

The Encryption package utilizes the Defuse PHP encryption library for encryption and decryption operations.

For more information on how to use the Defuse PHP encryption library, please refer to its documentation.

Note: Replace the ellipsis (...) in the usage examples with actual data or file paths relevant to your application. Always handle exceptions appropriately when performing encryption and decryption operations.
