learn hapi — How to Switch the JWT Signing Algorithm

Security is a high-priority concern in every application. You should always look out for vulnerabilities in used libraries and your infrastructure. The same holds true for JWT because the token signing contains a hashing or encryption part.

In this tutorial, you’ll learn how to switch the JWT signing algorithm, like switching from HS256 to HS512 or HS384 to RS256.

And the best part: you can deploy the updated code at any time without affecting your users. You’ll deploy with zero-downtime, your users don’t even notice the algorithm change at all!
