But I've encountered a problem and I'm not sure if it's related to the dotnetzip, to net.mail or I'm missing something.</p>\r\n<p>The thing is I email a weekly report in an Excel sheet, for security reasons now it has to be encrypted and protected with a password.</p>\r\n<p>This is how I do it:</p>\r\n<p>&nbsp;</p>\r\n<div style=\"color:Black;background-color:White\">\r\n<pre>    <span style=\"color:Blue\">Dim</span> objZIP <span style=\"color:Blue\">As</span> ZipFile = <span style=\"color:Blue\">New</span> ZipFile()<br>    <span style=\"color:Blue\">Dim</span> ms <span style=\"color:Blue\">As</span> MemoryStream = <span style=\"color:Blue\">New</span> MemoryStream<br>    objZIP.Password = <span style=\"color:#A31515\">&quot;PASSWORD!&quot;</span><br>    objZIP.Encryption = EncryptionAlgorithm.WinZipAes256<br>    objZIP.AddEntry(<span style=\"color:#A31515\">&quot;newfile.xls&quot;</span>, <span style=\"color:#A31515\">&quot;&quot;</span>, strXLSReport)<br>    objZIP.Save(ms)<br>    ms.Seek(0, SeekOrigin.Begin)<br>   <span style=\"color:Green\">' ...</span>\r\n    <span style=\"color:Blue\">Dim</span> emailMessage <span style=\"color:Blue\">As</span> System.Net.Mail.MailMessage = <span style=\"color:Blue\">New</span> System.Net.Mail.MailMessage<br>   <span style=\"color:Green\">' ...</span>\r\n    <span style=\"color:Blue\">Dim</span> ExcelZip <span style=\"color:Blue\">As</span> <span style=\"color:Blue\">New</span> System.Net.Mail.Attachment(ms, <span style=\"color:#A31515\">&quot;attachZip.zip&quot;</span>, Net.Mime.MediaTypeNames.Application.Zip)<br>    emailMessage.Attachments.Add(ExcelZip)<br>    objSMTPServer.Send(emailMessage)<br></pre>\r\n</div>\r\n<p>The email that I receive when executing this doesn't contain anything, and when I say anything I don't only mean the attachment, also recipient, subject, sender and body dissapear.</p>\r\n<p>If I remove the password assignment, it works perfect. I receive the email with all data and the attachment.</p>\r\n<p>I've also tried to save the protected zip to a folder (this worked perfect) and then attach and email it (in this case, the result was the same as using memorystream).</p>\r\n<p>I've made other tests such as changing encryption or the type of the zipped file, but all had the same ending.</p>\r\n<p>Any help or tips will be appreciated, thanks in advance!</p>\r\n<p>&nbsp;</p>\r\n<p>&nbsp;</p>",
