I was looking at the OpenIDConnect developer section https://openid.net/developers/certified/. There are multiple sections like:
- Certified Relying Party Libraries
- Certified Relying Party Servers and Services
- Certified OpenID Provider Libraries
- Certified OpenID Provider Servers and Services
- Certified OpenID Providers for Logout Profiles
I think I understand the difference between relying party (e.g. client app) and OpenID Provider (Authorization server) but I could not find details on what the above items mean.
