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 json-signer

JSON Signer and Validator

Signs JSON strings with a signed hash and validates signed strings.

Version 1.3

Alternatively, to return the signature and leave the JSON string intact, call signature() with the JSON string:

To validate a signed JSON string, call verify() passing the signed JSON string:

Validating a signature separately is as simple as passing the signature as the second argument to verify():

Signers

2 Signer classes are included:

The Signer defaults to AppendSigner, appending the signature key to the JSON object.

PackageSigner packages the original JSON object and signature key into a new parent object, i.e:

Be sure to use the correct Signer class for both signing and verifying

Signer classes may also be accessed directly:

Config

Signature Key

Set the key used to hold to signature in the signed string. This can be used to avoid collisions with existing keys.

If sign() is called on a string which already contains the signature key, an Exception will be thrown

Hash Algorithm

The signer defaults to using SHA256 as the signing algorithm. This can be changed, either via the second construct argument, or via setAlgorithm():

Package Key

When utilising the PackageSigner class, you may set the key used to hold to original JSON package in the signed string:
