# 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.
# Additional Context
- Closes https://github.com/zitadel/zitadel/issues/8031
- Part of https://github.com/zitadel/zitadel/issues/7809
- After https://github.com/zitadel/oidc/pull/637
- After https://github.com/zitadel/oidc/pull/638
Even though this is a feature it's released as fix so that we can back port to earlier revisions.
As reported by multiple users startup of ZITADEL after leaded to downtime and worst case rollbacks to the previously deployed version.
The problem starts rising when there are too many events to process after the start of ZITADEL. The root cause are changes on projections (database tables) which must be recomputed. This PR solves this problem by adding a new step to the setup phase which prefills the projections. The step can be enabled by adding the `--init-projections`-flag to `setup`, `start-from-init` and `start-from-setup`. Setting this flag results in potentially longer duration of the setup phase but reduces the risk of the problems mentioned in the paragraph above.

This implementation increases parallel write capabilities of the eventstore.
Please have a look at the technical advisories: [05](https://zitadel.com/docs/support/advisory/a10005) and [06](https://zitadel.com/docs/support/advisory/a10006).
The implementation of eventstore.push is rewritten and stored events are migrated to a new table `eventstore.events2`.
If you are using cockroach: make sure that the database user of ZITADEL has `VIEWACTIVITY` grant. This is used to query events.
This PR starts the OIDC implementation for the API V2 including the Implicit and Code Flow.
