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.
Please rate this library. Is it a good library?

Object Encryptor

Library provides interface for encrypting PHP arrays, stdclass objects and scalars. A cipher may contain additional metadata which limits the conditions under which it may be decrypted. The library uses the defuse/php-encryption encryption method with AWS KMS or Azure Key Vault managed keys or Google Cloud KMS.

Requirements

The library supports PHP 8.1+.

Usage

Entry point to the library is the ObjectEncryptorFactory class which creates instances of ObjectEncryptor class which has encryptGeneric, encryptForComponent, encryptForProject, encryptForConfiguration, encryptForProjectWide encryptForBranchType, encryptForBranchTypeConfiguration, encryptForProjectWideBranchType and corresponding decryptXXX methods. The actual encryption and decryption mechanisms are implemented using Crypto Wrappers. Crypto wrappers implement different verification methods using cypher metadata.

Usage

Initialize the library using the factory class:

Alternatively, you can use getAwsEncryptor and getAzureEncryptor and getGcpEncryptor to get cloud specific object encryptors.

Wrappers

Depending on the provided keys and parameters, the following wrappers will be available:

During encryption, the wrapper has to be specified (each encryptXXX method uses one). During decryption, the wrapper is chosen automatically by the cipher prefix. This means that decryptForConfiguration method is also capable of decrypting ciphers created by encryptForComponent or encryptForProject ciphers. If the wrapper is not available (key or parameters are not set or equal to those in the cipher), the value cannot be deciphered and an exception is thrown.
