Authenticator plugins for Requests that support JWT bearer tokens

requests-jwtauth

Authenticator plugins for Requests that support JWT bearer tokens.

Description

This package contains two classes, HTTPBearerAuth and JWTSecretAuth, that implement the AuthBase interface from the Requests package. The HTTPBearerAuth class takes a single bearer token value at initialization, and adds that to an Authorization: Bearer header. The JWTSecretAuth class takes a shared secret, and uses that to generate and sign short-lived JWT tokens to be added to an Authorization: Bearer request header. By default, these tokens are valid for 1 hour (3600 seconds), and may contain arbitrary JWT claims in their payload.

Dependencies

• Python 3.8+
• Requests
• JWCrypto

Installation

pip install requests-jwtauth

Usage

HTTPBearerAuth

import requests
from requests_jwtauth import HTTPBearerAuth

# send a request with a pre-obtained bearer token
my_token = '...'
r = requests.get('http://example.com', auth=HTTPBearerAuth(my_token))

JWTSecretAuth

import requests
from requests_jwtauth import JWTSecretAuth

# use a shared secret to generate (and automatically regenerate)
# short-lived JWT bearer tokens

secret_auth = JWTSecretAuth(
    # shared secret with the service that requires authentication
    secret='...',
    # JWT claims to place in the token payload
    # this class takes care of providing the 'exp' (expiration time) key
    claims={
        'sub': '...'
    },
    # Time-To-Live, in seconds; default is 3600 (i.e., 1 hour)
    ttl=3600,
    # instead of waiting for it to actually expire,
    # renew the token whenever the remaining time-to-live is
    # less than this number of seconds; default is 60
    expiration_buffer=60,
    # signing algorithm to use; defaults to H256
    signing_algorithm='H256'
)

r = requests.get('http://example.com', auth=secret_auth)
