It is a standalone .NET API to create, manipulate, extract & protect archive formats including ZIP, BZIP, BZ2 & TAR.

Aspose.ZIP for .NET class library allows your .NET applications to compress/decompress files and folders without getting into the complexity of coding new compression algorithms or understanding the existing ones. Enable your programs to work with a vast range of features, such as creating archives, saving archives, archive extraction, encrypting/decrypting archives, compressing single or multiple files as well as directory contents. It also allows you to apply security to your archived and compressed files and folders via password, AES (128, 192, 256) encryption, or mixed encryption.

Archive Processing Features

• Compress files and folders into standard ZIP formats.
• Supports Deflate, Bzip2 & LZMA compression algorithms.
• Apply simple password or AES128, AES192, AES256 encryption to archives.
• Employ different protection schemes for each file within an archive.
• Append more files to an existing zipped archive.
• Use Gzip or Bzip2 to pack files & folders into a TAR archive.
• Supports LZMA or LZMA2 compression & optional encryption to create 7z archives.
• Create self-extracting compressed archives.

}

Create 7z Archive with AES Encryption

Aspose.Zip for .NET allows you to apply password protection and encryption to zipped archives. The following C# code sample demonstrates the creation of a Seven Zip file with AES encryption setting.

using (var archive = new SevenZipArchive(new SevenZipEntrySettings(null, new SevenZipAESEncryptionSettings("p@s$"))))
{
   archive.CreateEntry("data.bin", new MemoryStream(new byte[] { 0x00, 0xFF }));
   archive.Save("archive.7z");
}
