Can I use Keycloak as a key store like Hashicorp Vault for an example? Keycloak has realm keys, can I use this feature as a secure key store and use it to encrypt and hash data in my web application? Is there an API that I can use to read those keys to use them in my web application? are these keys stored securely on disk?
If Keycloak is not built for that purpose, what should I use in combination with it? Can I integrate Keycloak with some other key vault?
