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.

CsrfToken

CSRF token package of the CodeCollab project

Build Status

Requirements

PHP7+

Installation

Include the library in your project using composer:

{
    "require-dev": {
        "codecollab/csrf-token": "^2"
    }
}

Usage

This library securely generates and validates CSRF tokens. To use this libray simply create a new \CodeCollab\CsrfToken\Token instance. A functioning concrete implementation is added as \CodeCollab\CsrfToken\Token\Handler:

``

To generate a new token (and invalidate the old token) simply call $csrfToken->generate().

``

Storage

This library only provides an interface for storage objects so you can use any storage you prefer. The storage must have a way to persist the token between requests (i.e. session). An example native session storage implementation may look like:

``

All storage implementations must implement CodeCollab\CsrfToken\Storage\Storage.

Generators

Generators are repsonsible for generating secure tokens. By default the CodeCollab\CsrfToken\Generator\RandomBytes32 generator is included which as the name suggest generates a 32 bytes long random token.

This generator uses PHP's native random_bytes() function to generate the tokens. When a token could not be generated a CodeCollab\CsrfToken\Generator\InsufficientStrengthException will be thrown. The generator interface only has a single method generate() will generates the tokens.

The supplied generator will be fine for most cases, but if you need additional security you can implement your own generator based on the CodeCollab\CsrfToken\Storage\Storage interface.
