Progression IProgress<double> sur compression et extraction

Utilisation rapide

// Créer
ZipArchive.Create("archive.zip", new[] { "file1.txt", "file2.pdf" });

// Créer avec AES-256
ZipArchive.Create("secure.zip", new[] { "secret.docx" }, new ZipOptions {
    Password   = "MonMotDePasse!",
    Encryption = ZipEncryption.Aes256
});

// Extraire
ZipArchive.ExtractToDirectory("secure.zip", "./output",
    new ZipOptions { Password = "MonMotDePasse!" });

// Lister
foreach (var e in ZipArchive.List("archive.zip"))
    Console.WriteLine(e);

Roadmap

  • ZIP64 (fichiers > 4 Go, extra field 0x0001)
  • DEFLATE from-scratch (LZ77 + Huffman canonique sans System.IO.Compression)
  • Streaming writer (Data Descriptor 0x0008 pour CRC/tailles en fin)
  • BZip2 (MethodId=12) et LZMA (MethodId=14)
  • Support multi-disk
  • Tests unitaires (compatibilité 7-Zip, WinZip, .NET ZipArchive)
