# Which Problems Are Solved
Streams allow differentiating logs produced by different components of
Zitadel.
# How the Problems Are Solved
The `backend/v3/instrumentation/logging` package now exposes convenience
function for setting and getting a logger from the context. As well as
high-level functions to emit log records at various levels. When
constructing a new logger a "stream" needs to be specified:
- **runtime**: General runtime logs, such as startup and shutdown
messages. Default for logs that do not belong to the other categories.
- **request**: Logs for incoming API and HTTP requests.
- **event_handler**: Logs for event handling in projections.
- **queue**: Logs for the job queue processing.
- **event_pusher**: Logs for event pushing to the database. Disabled by
default, contains sensitive information.
Each line from the returned logger contains a `stream` field as well as
a `version` field with the current Zitadel version.
## Runtime config
Streams can be enabled by passing an array of stream names in the
runtime config. Because some log streams may contain sensitive data
(especially events), it is now also possible to mask values by their
key.
# Additional Changes
- Wrap `slogctx` in the `logging` package. (Except API error converter
packages, because of import cycle)
- Add some docs to `logging` package so other devs understand how to add
logging to Zitadel
- Add `logging.OnError` and `logging.WithError` helper functions with
`Panic()` and `Fatal()` methods, to preserve current calls in the `cmd`
packages.
- Add instance context extractor.
- Only output request details in the request info log. Request ID
remains propagated through context.
- Moved middleware functionality into protocol specific packages.
- Removed setting of URI to context in metric middleware. There were ony
setters and no getters. (Unused value)
- Reuse a single statusWriter in the middleware package for middlewares
that need to know the response status.

- Closes#11331
- Partly #11330

# Which Problems Are Solved
Implement a new API service that allows management of OIDC signing web
keys.
This allows users to manage rotation of the instance level keys. which
are currently managed based on expiry.
The API accepts the generation of the following key types and
parameters:
- RSA keys with 2048, 3072 or 4096 bit in size and:
- Signing with SHA-256 (RS256)
- Signing with SHA-384 (RS384)
- Signing with SHA-512 (RS512)
- ECDSA keys with
- P256 curve
- P384 curve
- P512 curve
- ED25519 keys
# How the Problems Are Solved
Keys are serialized for storage using the JSON web key format from the
`jose` library. This is the format that will be used by OIDC for
signing, verification and publication.
Each instance can have a number of key pairs. All existing public keys
are meant to be used for token verification and publication the keys
endpoint. Keys can be activated and the active private key is meant to
sign new tokens. There is always exactly 1 active signing key:
1. When the first key for an instance is generated, it is automatically
activated.
2. Activation of the next key automatically deactivates the previously
active key.
3. Keys cannot be manually deactivated from the API
4. Active keys cannot be deleted
# Additional Changes
- Query methods that later will be used by the OIDC package are already
implemented. Preparation for #8031
- Fix indentation in french translation for instance event
- Move user_schema translations to consistent positions in all
translation files
# Additional Context
- Closes#8030
- Part of #7809
