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 laravel-aead

LaravelAEAD.

LaravelAEAD is a library which provides Advanced Encryption with Associated Data (AEAD) for Laravel.

Abstract:

This is a fork of hernandev/laravel-aead package by Diego Hernandes

This package replaces, when installed and enabled, the default encryption implementation of Laravel, which currently supports only two variants of the same block cipher, AES-128-CBC and AES-256-CBC.

The reason for only having two options is probably based on PHP history itself, like the (not so much) rececent depreciation of MCrypt.

As of PHP 7.2, we can now count on the exceptional libsodium extension, with supports the most secure AEAD construtions and it's variants.

AEAD stands for Advanced Encryption, with Associated Data, and they are algorithms which combine a stream cipher with a message authentication code (MAC).

The result of such combination is a encryption scheme with provides three aspects that are useful for modern applications:

For more information on AEAD, I highly recommend reading the libsodium documentation, which states the main parts, but, reading the construction IETF RFC's is also something interesting if you care for security.

Available Constructions.

Those are the libsodium AEAD constructors, and they respective key for usage with this package.

AEAD Cipher / Contruction Key Size Nonce Size Config Key (config/app.php)
XChaCha20-Poly1305-IEFT 256 bits 192 bits 'XCHACHA20-POLY1305-IEFT'
ChaCha20-Poly1305-IEFT 256 bits 96 bits 'CHACHA20-POLY1305-IEFT'
ChaCha20-Poly1305 256 bits 64 bits 'CHACHA20-POLY1305'
AES-256-GCM 256 bits 96 bits 'AES-256-GCM'

Installing & Configuring.

Installing the Library.

Changing the authentication provider (on config/app.php):

Configuring the cipher (also on config/app.php):

Usage.

After doing this install, all default Laravel encryption will be performed under the relative constructions / ciphers.

Meaning if you use encrypt() and decrypt(), they will use this package instead of the default encryption.

It also means that cookies & session, that should be encrypted, will use it.
