Cache store interface for the new JWKSourceBuilder

[Kenneth Leong]

It seems that in latest version 9.29 the RemoteJWKSet and DefaultJWKSetCache classes have been deprecated.
Replaced with JWKSourceBuilder and setting the caching, retrying mechanisms there.

Here is my issue, before this deprecation i was extending the DefaultJWKSetCache and overridding the put function to save and retrieve saved JWK keysets from sharedpreference in Android.

With the deprecation of RemoteJWKSet and DefaultJWKSetCache, how can I save and retrieve a cached keyset from sharedpreferences with these new apis?

Or rather how do i supply my own cache implementation to the JWKSourceBuilder?

At present there is no simple way to provide your own store for cached JWK sets.

Would you be interested in working on this and suggesting a PR?

The deprecated classes will be around for a long time, so it’s okay to continue using them.

BTW, here is a guide for how to use the new facility.

Fortunately there is already a CachedObject abstraction, what seems to be missing is an interface for its storage (rather than simply instantiating it as a variable).
