Jwk = token_key_id]Ĭert = x509.load_der_x509_certificate(der_cert, default_backend()) Token_key_id = jwt.get_unverified_header(token) I think including this feature in the library would be great for us users and will mitigate potential vulnerabilities of improper validation by everyone re-implementing reference solutions and making mistakes.įrom import default_backendįrom import serialization I think this makes it a very suitable place to include a def validate_token(self, audience.) -> DecodedToken: somewhere in the class ClientApplication(object): which then can be included into any middleware, but then at least the implementation is right there for the use, and potential security or performance impacting bugs in an area as critical as the validation of the tokens (performed on all requests) is avoided in the multitude of servers using the authorization code flow (or any other implementation that requires the token acquisition and validation to happen in the same application). And yes, this is a client authentication library, but the recommended most secure flow is the authorization code flow, which requires this to be run on the server in order to have control of how you issue tokens to the clients (client secrets). Of course, there are reference solutions out there as mentioned above. Call jwt.decode(itoken, public_key, audience=), supplying client_id of your application, and catch exceptions that it can raise.
Convert its public key part into PEM format.

Īlso, msal depends on pyjwt library, which contains API method for full JWT validation. But these checks do not include signature verification. A sufficient number of JWT validation checks is being performed in the _id_token(), which is called upon adding tokens into TokenCache: token_cache.py:137.
