Ok. Is there any way to craft an instance of a binary with different
metadata that generates the same checksum? Can you point me to the code which
performs this inspection and calculation? Where does the checksum reside in
transmission (i.e. the binary and checksum are sent separately, or it's just
calculated on one end and there is nothing to compare it to?)?
> Add extension bundles as a type of versioned item

> Key: NIFIREG-211
> URL: https://issues.apache.org/jira/browse/NIFIREG-211
> Project: NiFi Registry
> Issue Type: Improvement
> Reporter: Bryan Bende
> Assignee: Bryan Bende
> Priority: Major
> Fix For: 0.4.0
>
>
> This ticket is to capture the work for adding extension bundles to NiFi
> Registry.
> This work may require several follow on tickets, but at a high-level will
> include some of the following:
> - Add a new type of item called an extension bundle, where each bundle
> can contain one ore extensions or APIs
>
> - Support bundles for traditional NiFi (aka NARs) and also bundles for
> MiNiFi CPP
>
> - Ability to upload the binary artifact for a bundle and extract the
> metadata about the bundle, and metadata about the extensions contained
> in the bundle (more on this later)
>
> - Provide a pluggable storage provider for saving the content of each
> extension bundle so that we can have different implementations like
> local fileysystem, S3, and other object stores
>
> - Provide a REST API for listing and retrieving available bundles,
> integrate this into the registry Java client and NiFi CLI
> - Security considerations such as checksums and cryptographic signatures for
> bundles
