Hi @bshaffer
This is a breaking change that is currently not obvious from the 6.0 release notes.
As a notable example, Microsoft do not output JWK with the alg key populated:
https://login.microsoftonline.com/common/discovery/keys
I think the release notes should encourage developers to inspect JWK::parseKeySet beyond just its return type.
Thanks!

I just updated the release notes, @Nextra, thanks for the feedback.
I think it would be a better user-experience to have a second optional argument $algorithm to parseKeySet, to help with this edgecase.
$algorithm = 'RS256'; // default algorithm used when "alg" isn't set $jwks = JWK::parseKeySet($jwks, $algorithm);I didn't initially add it because I was hoping in practice that most JWKS would be populating the alg parameter. What do you think?
