Certipy (version 0.2.2) is a Python utility designed to simplify the creation and signing of Certificate Authorities (CAs) and certificates on the fly. It wraps `pyOpenSSL` to manage certificate records, maintain signing hierarchies, and persist certificates to files. The project appears to be in a maintenance status, with its latest PyPI release in March 2025, though active development on GitHub seems to have slowed since early 2023.

Certipy

✓ from certipy import Certipy

This quickstart demonstrates how to initialize Certipy, create a root Certificate Authority, and then generate a signed certificate using that CA. It also includes cleanup for the temporary certificate store directory.

from certipy import Certipy import os # Create a temporary directory for the store store_dir = os.path.join(os.getcwd(), 'cert_store') os.makedirs(store_dir, exist_ok=True) try: # Initialize Certipy with a store directory certipy_instance = Certipy(store_dir=store_dir) # Create a Certificate Authority (CA) ca_name = 'my_root_ca' certipy_instance.create_ca(ca_name) root_ca_record = certipy_instance.store.get_record(ca_name) print(f"Root CA '{ca_name}' created at: {root_ca_record.cert_path}") # Create and sign a key-certificate pair using the CA cert_name = 'my_server_cert' certipy_instance.create_signed_pair(cert_name, ca_name) server_cert_record = certipy_instance.store.get_record(cert_name) print(f"Signed certificate '{cert_name}' created at: {server_cert_record.cert_path}") finally: # Clean up the temporary store directory if os.path.exists(store_dir): import shutil shutil.rmtree(store_dir) print(f"Cleaned up directory: {store_dir}")

Known issues

gotchaThere are two distinct Python libraries named 'certipy' or similar, causing potential confusion. This entry refers to `certipy` by LLNL (version 0.2.2), which is a general-purpose PKI utility. The other, `certipy-ad` (by ly4k, version 5.x.x), is an Active Directory Certificate Services (AD CS) enumeration and abuse tool. Ensure you install and use the correct library for your needs.

fix

Always verify the GitHub repository and PyPI project page (github.com/LLNL/certipy for this library) before installation to confirm you have the intended project. For AD CS related tasks, you likely want `pip install certipy-ad` instead.

affects: All versions

gotchaThe `certipy` library internally relies on `pyOpenSSL` and `cryptography` for its core functionality. Compatibility issues with specific versions of these underlying libraries can sometimes occur. Always ensure your environment has compatible versions if you encounter obscure cryptographic errors.

fix

Check the `setup.py` of the `certipy` GitHub repository for the exact `pyOpenSSL` and `cryptography` version requirements. As of version 0.2.2, it requires `pyOpenSSL>=23.0.0` and `cryptography>=39.0.0`.

affects: All versions, especially with major updates to underlying crypto libraries

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'certipy'

The `certipy` package is not installed in your current Python environment.

fix

Install the package using pip: `pip install certipy`.

ImportError: cannot import name 'Certipy' from 'certipy'

This error often indicates that you might be trying to import `Certipy` from a different (or conflicting) package installed under a similar name, or the package structure has changed. It's also possible if you have a local file named `certipy.py` shadowing the installed package.

fix

Verify that you have installed the correct `certipy` library (`pip show certipy`) and that there isn't a local file or directory named `certipy.py` or `certipy/` in your project path that could be causing a name collision. The correct import is `from certipy import Certipy` for the LLNL project.
