SharpZipLib is a pure C# compression library for .NET supporting Zip (stored/deflate, PKZIP and AES encryption, Zip64), GZip, zlib, raw deflate, Tar, and BZip2 formats. It ships as a NuGet package and can be used from any .NET language without native dependencies.
Use cases
- create and extract zip archives in C#
- compress files with gzip in .NET
- read tar archives with long filenames
- password-protect zip files with AES encryption
- decompress bzip2 streams in .NET
- handle zip64 archives larger than 4GB
When to choose
- you need zip/gzip/tar/bzip2 support in pure managed .NET code without native DLLs
- you need AES-encrypted or Zip64 archives
- you want a mature MIT-licensed compression library for .NET
When to avoid
- you need Deflate64 support
- you only need basic zip handling and prefer the built-in System.IO.Compression
- you need formats like 7z or RAR
