andife / cyclonedx-python

Creates CycloneDX Software Bill of Materials (SBOM) from Python projects and environments.

CycloneDX Python SBOM Generation Tool

---

This project provides a runnable Python-based application for generating CycloneDX bill-of-material documents from either:

• Your current Python Environment
• Your project's manifest (e.g. Pipfile.lock, poetry.lock or requirements.txt)
• Conda as a Package Manager

The BOM will contain an aggregate of all your current project's dependencies, or those defined by the manifest you supply.

CycloneDX is a lightweight BOM specification that is easily created, human-readable, and simple to parse.

Read the full documentation for more details.

Installation

Install this from PyPi.org using your preferred Python package manager.

Example using pip:

pip install cyclonedx-bom

Example using poetry:

poetry add cyclonedx-bom

Usage

Call via one of commands:

cyclonedx-py
python3 -m cyclonedx_py

Basic usage

$ cyclonedx-py --help
usage: cyclonedx-py [-h] (-c | -cj | -e | -p | -pip | -r) [-i FILE_PATH]
                 [--format {json,xml}] [--schema-version {1.4,1.3,1.2,1.1,1.0}]
                 [-o FILE_PATH] [-F] [-X]

CycloneDX SBOM Generator

optional arguments:
  -h, --help            show this help message and exit
  -c, --conda           Build a SBOM based on the output from `conda list
                        --explicit` or `conda list --explicit --md5`
  -cj, --conda-json     Build a SBOM based on the output from `conda list
                        --json`
  -e, --e, --environment
                        Build a SBOM based on the packages installed in your
                        current Python environment (default)
  -p, --p, --poetry     Build a SBOM based on a Poetry poetry.lock's contents.
                        Use with -i to specify absolute path to a `poetry.lock`
                        you wish to use, else we'll look for one in the
                        current working directory.
  -pip, --pip           Build a SBOM based on a PipEnv Pipfile.lock's
                        contents. Use with -i to specify absolute path to a
                        `Pipfile.lock` you wish to use, else we'll look for
                        one in the current working directory.
  -r, --r, --requirements
                        Build a SBOM based on a requirements.txt's contents.
                        Use with -i to specify absolute path to a
                        `requirements.txt` you wish to use, else we'll look
                        for one in the current working directory.
  -X                    Enable debug output

Input Method:
  Flags to determine how this tool obtains its input

  -i FILE_PATH, --in-file FILE_PATH
                        File to read input from. Use "-" to read from STDIN.

SBOM Output Configuration:
  Choose the output format and schema version

  --format {json,xml}   The output format for your SBOM (default: xml)
  --schema-version {1.4,1.3,1.2,1.1,1.0}
                        The CycloneDX schema version for your SBOM (default:
                        1.4)
  -o FILE_PATH, --o FILE_PATH, --output FILE_PATH
                        Output file path for your SBOM (set to '-' to output
                        to STDOUT)
  -F, --force           If outputting to a file and the stated file already
                        exists, it will be overwritten.
  -pb, --purl-bom-ref   Use a component's PURL for the bom-ref value, instead
                        of a random UUID

Advanced usage and details

Python Support

We endeavour to support all functionality for all current actively supported Python versions. However, some features may not be possible/present in older Python versions due to their lack of support.
