-----------------------------------
Summary: Handle flowfile repository encryption status change on
startup
Key: NIFI-6994
URL: https://issues.apache.org/jira/browse/NIFI-6994
Project: Apache NiFi
Issue Type: Sub-task
Components: Core Framework
Affects Versions: 1.2.0
Reporter: Andy LoPresto
Assignee: Andy LoPresto
If the content repository changes from encrypted -> unencrypted or vice-versa
on startup, the application should handle the change.
* Unencrypted -> encrypted: Attempt to create an {{InputStream}} instance to
read the existing content into memory and write them back using
{{EncryptedContentRepositoryOutputStream}}
* Encrypted -> unencrypted: Attempt to create a {{CipherInputStream}} instance
to read the existing events into memory and write them back using
{{OutputStream}}. This depends on the key(s) for the key IDs used still being
available via {{nifi.properties}}.
This process may be very slow given large existing repositories, so a
standalone tool should also be made available to perform this process outside
of the running app.
