Answer 1

DotNetZip allows you to do this. From their documentation:

The library supports zip passwords, Unicode, ZIP64, stream input and output, AES encryption, multiple compression levels, self-extracting archives, spanned archives, and more.

Answer 2

With Dotnetzip library you can zip even more than 4 gb. Also a lot easer to use then working with filestreams and bytearrays.

using (ZipFile zip = new ZipFile()) {
    zip.CompressionLevel = CompressionLevel.BestCompression;
    zip.UseZip64WhenSaving = Zip64Option.Always;
    zip.BufferSize = 65536*8; //buffer size

    foreach (var file in filenames) {
        zip.AddFile(file);
    }
    zip.Save(outpath);
}
