Client Side Encryption of KeyCloak DB

In this discussion the encryption of KeyCloak’s database was defined:
Secure Credentials Store Discussion · Issue #10 · keycloak/keycloak-community (
but I can only find the possibility to use a KeyVault to save secrets:
keycloak-documentation/vault.adoc at master · keycloak/keycloak-documentation (
I’m I wrong here or is client-side encryption not implemented at the keycloak db? Thank you for your help!
