带有AESKeySize参数的ZipEntry似乎不允许解压缩/解压缩

Question

下面的代码似乎工作得很好。但是，当我将加密值(注释掉的代码)应用到ZipEntry时，一切似乎就分崩离析了。我得到了以下例外: ICSharpCode.SharpZipLib.Zip.ZipException：“不支持此条目的压缩方法”。目前，我不知道“压缩方法”有什么问题。我尝试了所有这些方法，并将压缩级别设置为0。似乎什么都起不到作用。有人能帮我吗？

using ICSharpCode.SharpZipLib.Core;
using ICSharpCode.SharpZipLib.Zip;
using System;
using System.IO;

    public byte[] ZipPayload(byte[] data)
    {
        using (var outputStream = new MemoryStream())
        using (var zipStream = new ZipOutputStream(outputStream))
        {
            zipStream.Password = "abc";
            zipStream.SetLevel(0);

            var zipEntry = new ZipEntry("ZipEntry")
            {
                //AESKeySize = 128,
                //CompressionMethod = CompressionMethod.Stored
                //CompressionMethod = CompressionMethod.Deflated
                //CompressionMethod = CompressionMethod.Deflate64
                //CompressionMethod = CompressionMethod.BZip2
                //CompressionMethod = CompressionMethod.LZMA
                //CompressionMethod = CompressionMethod.PPMd
                //CompressionMethod = CompressionMethod.WinZipAES
                //CompressionMethod = CompressionMethod.WinZipAES
            };
            zipStream.PutNextEntry(zipEntry);

            var inputMemoryStream = new MemoryStream(data);
            StreamUtils.Copy(inputMemoryStream, zipStream, new byte[4096]);
            zipStream.CloseEntry();
            zipStream.IsStreamOwner = false;

            return outputStream.ToArray();
        }
    }

    public byte[] UnzipPayload(byte[] data)
    {
        using (var outputStream = new MemoryStream())
        using (var inputStream = new MemoryStream(data))
        {
            using (var zipStream = new ZipInputStream(inputStream))
            {
                zipStream.Password = "abc";
                zipStream.GetNextEntry();
                zipStream.CopyTo(outputStream);
            }
            return outputStream.ToArray();
        }
    }

看起来，为了解压缩有效载荷，您需要使用如下内容：

  using (var zipFile = new ZipFile(stream))
  {
       zipFile.Password = "abc"
       var zipEntry = zipFile.GetEntry("ZipEntry");

       using (var zipInputStream = zipEntry.GetInputStream(zipEntry))
       {

       }
  }
