unzipping a zip file with a password

    Sorry for the post but cannot get the help file open. Can I open a password protected zip file in vb 2008.

DotNetZip works with PKZip (weak) encryption, which does not protect the entire zip archive.

I think there are some extensions to the zip specification that allow the entire archive to be password protected, but DotNetZip does not support any of those extensions.

If you have an archive that uses PKZip encryption, ZipEntry.ExtractWithPassword() is the method you want for extracting an entry that is protected with a password.
