Re: JWT (was: Upcoming Spring 2021 RPG enhancements)

Yes, ILeastic supports HS256 (HMAC using SHA256).

But not RS256 (RSA using SHA256).

The problem is that HS256 is a shared secret, and

Sharing the HMAC secret with a third-party service creates a significant
vulnerability. Even sharing the secret between different services within a
single architecture is not recommended. If all services share the same key,
the compromise of a single service immediately becomes an architecture-wide
problem.

For simple stuff, it's fine, but once you have a separate authentication
server and numerous secured resources, RS256 is the way to go.

Agreed that IWS can't - although I believe it is high on their wish list.
But as noted yesterday ILeastic offers routines for one "flavour" and I use
them in my RPG routines that talk to Zoom APIs.

I'm curious as to why you'd want to use JWTs (unless you're having to

particularly suitable to systems of our scale.

Huh? I don't understand where you'd get that idea.

JSON Web Tokens (JWT) are an open, industry standard RFC 7519 method for
representing claims securely between two parties.

The rest of the world uses JWTs to among other things secure the APIs

they

are building. The API is one side and the other is your selected

identity

provider.

While nodejs web-services on the i could validate them, IWS or other RPG
ones currently can not.
