# Limitations

There are the following few limitations when working with <code class="expression">space.vars.ionos\_cloud</code> Container Registry APIs:

* You cannot choose your encryption keys (Trust-No-One) when encrypting data at rest; the Container Registry platform manages the keys.
* It is not possible to grant repository access permissions to push, pull, or delete from a specific repository.
* Any unauthenticated user will not be able to access the registry contents.
