Generate signed tokens for Cloudflare Stream in Python

cloudflare_stream_token.py

import base64
from datetime import datetime

from jwcrypto import jwt, jwk  # pip install jwcrypto

b64_jwk = "XXXX"  # Base64-encoded JWT you get from Cloudflare Stream API (https://developers.cloudflare.com/stream/viewing-videos/securing-your-stream#step-1-call-the-streamkey-endpoint-once-to-obtain-a-key)
jwk_key = jwk.JWK.from_json(base64.b64decode(b64_jwk))

def get_video_token(video_id: str, lifetime: int = 3600) -> str:
    header = {"kid": jwk_key["kid"], "alg": "RS256"}
    payload = {
        "sub": video_id,
        "kid": jwk_key["kid"],
        "exp": int(datetime.now().timestamp() + lifetime),
    }
    token = jwt.JWT(header=header, claims=payload)
    token.make_signed_token(jwk_key)
    return token.serialize()

Thank you so much
