Tools for Azure Active Directory JWT Tokens
Example: OpenIdDiscovery to get a signature key
In this example we use the openid discovery metadata to find a signing public key for a tenant. Common scenario is a JWT signature validation.
from azjwt import *
url = tenant_metadata_endpoint("3a15932d-3fd9-4278-a753-beb05cdf0c6d")
discovery = OpenIdDiscovery(url)
key = discovery.get_key("nOo3ZDrODABD1jKWhXslMN_KXEg")
rsa = jwk_to_rsa_pem(key)
print(rsa.decode())
The result of the execution of this code is a RSA key:
-----BEGIN PUBLIC KEY-----

-----END PUBLIC KEY-----
The key id (kid) could be obtained from the JWT token, using PyJWT package. Here is an example:
import jwt
headers = jwt.get_unverified_headers(token)
key_id = headers["kid"]
