## What it is
SSZipArchive is an Objective-C/Swift utility library for creating and extracting zip archives on Apple platforms (iOS, macOS, tvOS, watchOS, visionOS). It supports password-protected and AES-encrypted zips, large files, and configurable compression levels, built on minizip/zlib.

## Use cases
- unzip zip files in an iOS app
- create password protected zip files on macOS
- extract AES encrypted zip archives in Swift
- zip a directory of files on tvOS
- compress NSData instances into a zip with a filename
- create large zip files over 4.3GB

## When to choose
- you need zip support in an Objective-C or Swift app on Apple platforms
- you need AES-encrypted or password-protected zip archives
- you need CocoaPods, SPM, or Carthage integration
- you need to handle very large zip files

## When to avoid
- you target OS versions older than iOS 15.5 / macOS 10.15
- you need zip support on non-Apple platforms
- you prefer a pure Swift implementation like ZIPFoundation
- you need formats other than zip

## Facets
- artifact type: library
- maturity: stable
- function: compression, file-system, cryptography
