## What it is
Rubyzip is a Ruby library (gem) for reading and writing zip archives, including support for AES encryption. It provides both high-level Zip::File APIs and streaming InputStream/OutputStream classes.

## Use cases
- create zip archives in ruby
- extract files from a zip archive
- read and write zip files in a rails app
- create password-protected or AES-encrypted zips
- stream zip entries without loading everything into memory
- package files for download in a web app

## When to choose
- you need zip read/write support in a Ruby project
- you need encrypted zip archives in Ruby
- you want a mature, widely-used Ruby zip gem

## When to avoid
- you need tar, gzip, or 7z formats rather than zip
- you are not working in Ruby
- you need very high-performance native compression

## Facets
- artifact type: library
- maturity: stable
- function: compression, file-system, cryptography
- domain: files, developer-tools, security
- platform: ruby, cross-platform
- tags: zip, zip-archive, aes-encryption, ruby-gem, archive
