# Which Problems Are Solved
Use web keys, managed by the `resources/v3alpha/web_keys` API, for OIDC
token signing and verification,
as well as serving the public web keys on the jwks / keys endpoint.
Response header on the keys endpoint now allows caching of the response.
This is now "safe" to do since keys can be created ahead of time and
caches have sufficient time to pickup the change before keys get
enabled.
# How the Problems Are Solved
- The web key format is used in the `getSignerOnce` function in the
`api/oidc` package.
- The public key cache is changed to get and store web keys.
- The jwks / keys endpoint returns the combined set of valid "legacy"
public keys and all available web keys.
- Cache-Control max-age default to 5 minutes and is configured in
`defaults.yaml`.
When the web keys feature is enabled, fallback mechanisms are in place
to obtain and convert "legacy" `query.PublicKey` as web keys when
needed. This allows transitioning to the feature without invalidating
existing tokens. A small performance overhead may be noticed on the keys
endpoint, because 2 queries need to be run sequentially. This will
disappear once the feature is stable and the legacy code gets cleaned
up.
# Additional Changes
- Extend legacy key lifetimes so that tests can be run on an existing
database with more than 6 hours apart.
- Discovery endpoint returns all supported algorithms when the Web Key
feature is enabled.

* implicit for oidc session API
* implement authorize callback handler for legacy implicit mode
* upgrade oidc module to working draft
* add missing auth methods and time
* handle all errors in defer
* do not fail auth request on error
the oauth2 Go client automagically retries on any error. If we fail the auth request on the first error, the next attempt will always fail with the Errors.AuthRequest.NoCode, because the auth request state is already set to failed.
The original error is then already lost and the oauth2 library does not return the original error.
Therefore we should not fail the auth request.
Might be worth discussing and perhaps send a bug report to Oauth2?

* fix(oidc): ignore public key expiry for ID Token hints
This splits the key sets used for access token and ID token hints.
ID Token hints should be able to be verified by with public keys that are already expired.
However, we do not want to change this behavior for Access Tokens,
where an error for an expired public key is still returned.
The public key cache is modified to purge public keys based on last use,
instead of expiry.
The cache is shared between both verifiers.
