How to set password on Saving & opening the zip file.

Good day,

      I have a code as follows to compress I just copied it from the documentation:

private string CompressString(string str)
        {
            MemoryStream memoryStream = new MemoryStream();
            ZipCompression method = ZipCompression.Default;
            ZipOutputStream zipOutputStream = new ZipOutputStream(memoryStream, method);
            StreamWriter writer = new StreamWriter(zipOutputStream);
            writer.Write(str);
            writer.Flush();
            return Convert.ToBase64String(memoryStream.ToArray());
        }


  What is missing is to decompress it, I tried the following code but it doesn't give me the correct output

private string UnCompressString(string str)
        {

            MemoryStream memoryStream = new MemoryStream(Convert.FromBase64String(str));
            ZipInputStream input = new ZipInputStream(memoryStream);
            StreamReader reader = new StreamReader(input.BaseStream);
            string strData = reader.ReadToEnd();
            return strData;

        }

  When I tried to call the uncompressstring method, it does not give me the original text.

Thanks

Is there a way to unzip from the ZipPackage? My current routine is incorrect.

Here are my two routines (zip and unzip):

        public static void ZipStream(Stream oInStream, string sFileName, Stream oZipStream)
        {
            ZipPackage oZipPackage = ZipPackage.Create(oZipStream);
            oZipPackage.AddStream(sFileName, oInStream);
        }
 
        public static Stream UnzipStream(Stream oZipStream, int iIndex = 0) //this is incorrect; returns zipped stream
        {
            ZipPackage oZipPackage = ZipPackage.Open(oZipStream, FileAccess.Read);
            return oZipPackage.ZipPackageEntries[iIndex].OpenInputStream();
        }

Hello.

Does ZipLibrary of RadControls support ZIP encryption specs like AES 128?
I cannot find related description in your site.

I'm downloading a ZIP file handler and do a verification with the ZipPackage and gives me a method not supported error

My code:

Thank you very much in advance

Hey guys, I got the following stored in a text (.txt) file, which is, of course, zipped:
Hello World!

However, if I read the file like:

ZipInputStream zis = new ZipInputStream(entry.OpenInputStream());                             
StreamReader streamReader = new StreamReader(zis);                             
String text = streamReader.ReadToEnd();

The string (text) is:
ello World!

Am I doing something wrong or is this a bug (a read() instead of a peek() somewhere)?

Thank you!
