Encryption and MemoryStream

Aug 13, 2009 at 11:48 PM

I'm trying to create Encrypted in Memory ZIP which can be attached to E-mail, but it seems to be not working properly for me. Please let me know what's wrong with my code.  Setting Encryption and Password at ZipFile dosen’t work either.

MemoryStream mstrm = new MemoryStream();
using(ZipFile zip = new ZipFile())
ZipEntry entry = zip.AddEntry("test.txt", "", "HelloWorld");
entry.Password = "hello";
entry.Encryption = EncryptionAlgorithm.WinZipAes256;

It saves fine and can be opened using WinZip but when try to extract file it fails with invalid password.

Thanks for reporting the problem.  I believe this is fixed in v1.8.4.18, which you can download now.
