Encrypted Content Repository

While OS-level access control can offer some security over the flowfile content data written to the disk in a repository, there are scenarios where the data may be sensitive, compliance and regulatory requirements exist, or NiFi is running on hardware not under the direct control of the organization (cloud, etc.). In this case, the content repository allows for all data to be encrypted before being persisted to the disk. For more information on the internal workings of the content repository, see NiFi In-Depth - Content Repository.
