David Handermann commented on NIFI-7777:
----------------------------------------

The CompressContent processor does not currently support Zip archives, so the 
Zip4j library does not appear applicable to the CompressContent processor, 
unless I am missing something.  Support for creating encrypted Zip files could 
be added to the MergeContent Processor, with the addition of a Password 
property, and additional properties for Encryption Method and AES Key Size.  
The PR for NIFI-7836 includes several proposed enumerations for cryptographic 
definitions, which could also be applicable to the MergeContent processor when 
supporting encryption.  Would it make sense to have a separate story for 
supporting encrypted Zip files in MergeContent?
