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

Well, because they cannot be, having a short lifetime isn't the same as revocability. If you have short lived tokens, then you need a refresh mechanism which adds yet more complexity, and you have to balance the lifetime of the token against the need to keep refreshing it, which in any case feels like a dirty hack to overcome the basic problem of non-revocability. For most web apps I don't see what benefit you get for all this added complexity.

Tim,

Not sure why you think they can't be invalidated...

Every JWT should have an expires tag with a limited lifetime..

I know what they are, in fact I even wrote a MariaDB implementation of
them, but I decided against using them in my app for the reasons I mention
in my reply to Jon, namely, they cannot be invalidated. I get that the
federated identity might be useful, but I don't think applications of the
kind of scale we would run on an IBM i generally warrant the need for a
stateless solution, especially not at the expense of not being able to
invalidate tokens that might be being abused.

I'm curious as to why you'd want to use JWTs (unless you're having to
consume them somehow), their use case seems to be fairly limited and not
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.
