In AEM 6.3, the crypto key storage was moved from the filesystem to the JCR.

Is it possible to move it back to the filesystem?

Environment

AEM >= 6.3

Answer

The key provider storage type cannot be changed after initialization (similar to a runmode).

However, if the system has not been initialized yet, then the following JVM parameter can be added to the java command (before -jar) to keep the crypto key on the filesystem:

-Dcom.adobe.granite.crypto.file.disable=false
