encoded_jwt=\'         


        

Answer 1

There are some issues in the pyjwt library. and you must get the public key from the certificate.

I used openssl x509 -pubkey -noout -in cert.pem > pubkey.pem

then from the public key I could easily decode it using authlib library.

from authlib.specs.rfc7519 import jwt

encoded_jwt='''eyJ0eXAiOiJ....'''
secret=b'''-----BEGIN PUBLIC KEY-----
......
-----END PUBLIC KEY-----'''
claims = jwt.decode(encoded_jwt, secret)
print(claims)
