CycloneDX PHP Composer Plugin

A plugin for PHP's Composer that generates Software Bill of Materials (SBOM) in CycloneDX format.

Based on OWASP Software Component Verification Standard for Software Bill of Materials's criteria, this tool is capable of producing SBOM documents almost passing Level-2 (only signing needs to be done externally).

The resulting SBOM documents follow official specifications and standards, and might have properties following cdx:composer Namespace Taxonomy .

Requirements

  • PHP ^8.1
  • Composer ^2.3

However, there are older versions of this plugin available, which support PHP ^5.5||^7.0||^8.0 with Composer ^1.0||^2.0 .

Installation

As a global Composer plugin:

composer global require cyclonedx/cyclonedx-php-composer

As a development dependency of the current project:

composer require --dev cyclonedx/cyclonedx-php-composer

Usage

After successful installation, the Composer command CycloneDX:make-sbom is available.

$ composer CycloneDX:make-sbom --help

Description:
  Generate a CycloneDX Bill of Materials from a PHP Composer project.

Usage:
  CycloneDX:make-sbom [options] [--] [<composer-file>]

Arguments:
  composer-file                                       Path to Composer config file.

                                                      This might result in loss of time- and random-based-values.
      --validate|--no-validate                        Formal validate the resulting BOM.
      --mc-version=MC-VERSION                         Version of the main component.
                                                      This will override auto-detection.

  -q, --quiet                                         Do not output any message

Demo

How it works

This tool utilizes composer itself, to collect evidence for installed composer packages.
In terms of evidence collection, actually installed setups are preferred over pure lock file analysis.
Required evidence:

  • composer config/manifest file (e.g. composer.json file)
  • any of:
    • an actual composer setup (the result after running composer install [...] on your project)
    • a working composer lock file (e.g. composer.lock file)

Internals

This tool utilizes the CycloneDX PHP library to generate the actual data structures, normalize/serializ them and validate the SBOM result.

This tool does not expose any additional public API or classes - all code is marked as @internal and might change without any notice during version upgrades.
