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
                        `Pipefile.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 it's 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

See the full documentation for advanced usage and details on input formats, switches and options.

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.
