PyPIToken: Manipulate PyPI API tokens
PyPIToken is an open-source Python 3.6+ library for generating and manipulating PyPI tokens.
PyPI tokens are very powerful, as that they are based on Macaroons. They allow the bearer to add additional restrictions to an existing token. For example, given a PyPI token that can upload releases for any project of its owner, you can generate a token that will only allow some projects, or even a single one.
Here's an example:
$ pip install pypitoken import pypitoken token = pypitoken.Token.load("pypi-foobartoken") print(token.restrictions) # [NoopRestriction()] token.restrict(projects=["requests"]) print(token.restrictions) # [NoopRestriction(), ProjectsRestriction(projects=["requests"])] token.dump() # pypi-newfoobartoken
This token we've created above will be restricted to uploading releases of
requests. Of course, your PyPI user will still need to have upload permissions on
requests for this to happen.
The aim of this library is to provide a simple toolbelt for manipulating PyPI tokens. Ideally, someday, PyPI (Warehouse) itself may generate their tokens using this library too. This should make it easier to iterate on new kinds of restrictions for PyPI tokens, such as those discussed in the original implementation issue.
A discussion for integrating this library to the Warehouse environment is ongoing:
- In the Python Packaging discussions for putting the project under the PyPA umbrella
- In the Warehouse tracker for replacing the current macaroon implementation with this lib
