             Summary: cayenne-crypto: Lazy initialization of crypto subsystem
                 Key: CAY-2107
                 URL: https://issues.apache.org/jira/browse/CAY-2107
             Project: Cayenne
          Issue Type: Improvement
            Reporter: Andrus Adamchik
            Assignee: Andrus Adamchik


I have a deployment scenario where secret keys are not available on app startup, and users "unlock" the KeySource at a later time. Until then I'd still like my Cayenne stack to be operational for entities that do not require encryption. Currently this is not possible as DefaultValueTransformerFactory and DefaultBytesTransformerFactory are initialized eagerly and that requires a working KeySource. 

A possible solution to that is lazy initialization of DefaultValueTransformerFactory and DefaultBytesTransformerFactory which can be achieved via decoration in DI, that injects decorated instance as a Provider.
