A collection of Python modules used for interacting with IBMCloud IAM API services

Project description

ibmcloud-iam-python-client

PyPi Downloads License Build Status

This project is a collection of Python modules used for interacting with IBMCloud IAM API services.

Currently it includes support for:

  • Requesting IAM tokens using an intelligent caching mechanism (TokenManager)
  • Parsing IAM tokens and verifying their cryptographic signatures
  • Checking user action authorizations for a service, given a Subject, Action and Resource set (PDPClient)

It is meant to be a lightweight client library that can be used in other projects, such as a service or other client.

Some things that will be added soon in the future:

  • Caching authorization decisions from PDP
  • Support for list a users Roles assigned from IAM policies

Usage

Install

pip install ibmcloud_iam

Getting tokens with TokenManager

import os

from ibmcloud_iam.token import TokenManager

tm = TokenManager(api_key=os.environ["IBMCLOUD_API_KEY"])

# whenever you need a token, just use 'tm.get_token()'
# get_token() will return a cached token if the token is not expired,
# or if expired or otherwise invalid, retrieve a new token for you

# gets a new token
print(tm.get_token())

# will return the same token as above, because of caching
print(tm.get_token())

Parsing and Validating Tokens

import os

import ibmcloud_iam.token
from ibmcloud_iam.token import TokenManager

tm = TokenManager(api_key=os.environ["IBMCLOUD_API_KEY"])

# validate_token will check the signature and parse and return the token claims
claims = ibmcloud_iam.token.validate_token(tm.get_token())

print(claims)

PDP Authorizations

Please see example.py for an example on how to use the PDPClient
