certomancer 0.6.0

PKI testing tool

Certomancer

Quickly construct, mock & deploy PKI test configurations using simple declarative configuration. Includes CRL, OCSP and time stamping service provisioning.

Install with python setup.py install. See example.yml for an example config file, and below for more detailed documentation.

Requires Python 3.7 or later.

Quick start

$ pip install 'certomancer[web-api,pkcs12]' 
$ certomancer --config example.yml animate

This will run the Certomancer Animator WSGI app on your local machine, behind a development web server. Point your browser to http://localhost:9000 and take a look around. For more information, see the documentation below.

Demo

There's a demo on asciinema.org, demonstrating some of the core features of Certomancer. See link below.

Features

• Certomancer's core APIs are stateless: the same request should always return the same result. This property makes it very useful for automated testing.
  • Note that "the same result" does not necessarily mean "byte-for-byte equal". This is because some signing schemes (like ECDSA) involve random nonces. In addition to that, time is also a factor in certain cases (but Certomancer does permit time manipulation).
• Declarative, YAML-based configuration.
• Minimal input validation, so you can generate deliberately broken certificates if you need to.
• requests-mock integration.
• Ultra-lightweight WSGI application: the Certomancer Animator serves CRLs, OCSP responses, timestamps and more. This component requires Werkzeug, and optionally Jinja2 for the index view. Other than a web server and WSGI application server, there are no application dependencies.
• Plugin framework to support arbitrary certificate / CRL extensions and additional services. These plugins are compatible with the WSGI and requests-mock integrations without additional configuration.
• Certomancer is composable: since the Certomancer Animator is a bare-bones WSGI application, you can plug it into whatever web application framework you want with minimal overhead. Hence, for particularly complicated scenarios where the plugin API or existing integrations aren't sufficient, it is very easy to use Certomancer as a library, or wrap it as a component of some other WSGI application.
• With pyca/cryptography installed, Certomancer can also output PKCS#12 files if your tests require those.

Non-features

Certomancer is a testing tool for developers that write software to interface with public-key infrastructure. It is NOT intended to be used to manage production PKI deployments. Certomancer is very much garbage-in garbage-out, and happily ignores validation & security best practices in favour of allowing you to abuse your codebase in the worst possible ways. Consider yourself warned.
