Hi Doug,

Thanks for taking time and providing your feedback. Please provide more whenever you see mistakes.

For this one, I was anyway planning to write an updated article using web crypto APIs. Your feedback got that done.

Please see the updated article here: https://medium.com/deno-the-complete-reference/sign-verify-jwt-hmac-sha256-4aa72b27042a

Please check it out. If it still doesn't work for you, do let me know.
