7-zip and other applications allow you to “password-protected” a zip archive (using some encryption, usually AES.) The zip erlang module unfortunately does not support this feature, as per the documentation: The zip module supports zip archive versions up to 6.1. However, password-protection and Zip64 are not supported. So I’m wondering what would be the best strategy to handle that: is there another erlang / elixir library that would handle this ? should I find the C library behind the zip exe (if opensource ?) and call it (woud ports be the right tool ?) should it be possible to create the zip in erlang and encrypt it out of bound ? or should I just give up on trying to do this with code, and assume a external client-line tool (zip, 7zip, etc…) is available to generate the file out of the application (using System.cmd ?)

Packages | Hex - seems like zstream has support?

I does seem to. I missed it on hex, thanks ! :man_facepalming:

Try with zstream hex-package Zstream — zstream v0.6.7

The zstream lib can not create multivolume archive, and if I want to create multivolume archive what lib/method should be use? thanks much! For my scenario, I choose to execute external executable program (7zz for Linux environment) for create multivolume archive, the code like follow: appdir = Application.app_dir(:APPNAME) System.cmd("#{appdir}/priv/executable/7zz", ["a", "-tzip", "target_zip_name.zip", "/dir1/dir2/source_file_name.zip", "-v100k"])
