Verification of incoming token

[marcesengel]

Hi,

first of all thanks a lot for the work on this package! Looking through the README, I was wondering if jwt.decode(idToken) is actually the right thing to do, or if it'd make sense to also verify the incoming token? For now I'm verifying them, is this redundant? I'm not aware of the exact auth flow. Thanks in advance!

Best regards

Verification is great - and in fact recommended. I feel this should be part of the repo itself where it does that step just to ensure its not a replay attack or the token hasn't been tampered with. https://developer.apple.com/documentation/sign_in_with_apple/sign_in_with_apple_rest_api/verifying_a_user

@ananay thanks for the response! I've actually implemented getting the public keys from the api endpoint, caching them etc. - would you like me to share a gist so you might be able to copy & paste it?

I'd suggest to say so in the docs instead of suggesting jwt.decode(...), what do you think? 🤔
