David Handermann updated NIFI-8764:
-----------------------------------
Status: Patch Available (was: In Progress)
> Refactor UnpackContent to use Commons Compress and Zip4j
> --------------------------------------------------------
>
> Key: NIFI-8764
> URL: https://issues.apache.org/jira/browse/NIFI-8764
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Affects Versions: 1.13.2, 1.13.1, 1.13.0
> Reporter: David Handermann
> Assignee: David Handermann
> Priority: Minor
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Updating the {{UnpackContent}} processor to support optional decryption of
> password-protected Zip files changed the implementation library from Apache
> Commons Compress to Zip4j. Although Zip4j supports most standard Zip
> operations, it does not currently support certain alternative compression
> algorithms, such as bzip2. Apache Commons Compress does not support
> decryption of password-protected Zip files.
> In order to support the widest range of available Zip formats,
> {{UnpackContent}} should default to using Apache Commons Compress for Zip
> files, and use Zip4j when the processor is configured with the Password
> property.
