Absence of XML Encryptor and unencrypted key persistence

In my application developed in ASP.NET 6 Core, using the clean architecture, I came across the following error in the system log: "Microsoft.AspNetCore.DataProtection.KeyManagement.XmlKeyManager[35]: No XML encryptor configured. Key {7a5adceb-a160-445b-974a-41f45a896f68} may be persisted to storage in unencrypted form." The error indicates that an XML Encryptor has not been configured in the application. As a result, the key with the value {7a5adceb-a160-445b-974a-41f45a896f68} might be being stored in unencrypted storage.
