Aspose.ZIP for Java class library allows your Java 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 using ZipCrypto or AES (128, 192, 256) encryption or mixed encryption.

• Compress files and folders into standard ZIP format using Deflate, Bzip2, LZMA or PPMd compression algorithm.
• Extract RAR4 and RAR5 archives, with and without encryption.
• Apply simple password or AES128, AES192, AES256 encryption to archives.
• Employ different protection scheme to each file within an archive.
• Append more files to an existing zipped archive.
• Use Gzip, Bzip2, Xz, Z and Lzip to pack files & folders into a TAR or Cpio archive.
• Supports LZMA, LZMA2 or Bzip2 compression & optional encryption to create 7z archives.
• Track progress of compression.
• Create self-extracting compressed archives.

Compression: Zip, Tar, Cpio, GZip, Bz2, Z, Xz, Lzip, 7z

Decompression: Zip, Rar, Cab, Tar, Cpio, GZip, Bz2, Z, Xz, Lzip

try (Archive archive = new Archive()) {
   archive.createEntry("entry_name.dat", "input_file.dat");
   archive.save("result_archive.zip");
}

try (Archive archive = new Archive("input_archive.zip")) {
   archive.extractToDirectory("outputDirectory");
}

try (SevenZipArchive archive = new SevenZipArchive(
        new SevenZipEntrySettings(null, new SevenZipAESEncryptionSettings("p@s$")))) {
    archive.createEntry("data.bin", new ByteArrayInputStream(new byte[] { 0x00, (byte)0xFF }));
    archive.save("result_archive.7z");
}
