我想用Microsoft.Exchange.WebServices.Data发送加密的电子邮件。加密Microsoft.Exchange.WebServices.Data中的电子邮件
public void SendMessage(FacadeModel.EmailMessage message)
{
var item = new EWS.EmailMessage(_mailService);
var handler = new SecureMimeMessageHandler();
byte[] con = handler.encry("test", "[email protected]");
item.MimeContent = new EWS.MimeContent(Encoding.ASCII.HeaderName, con);
item.ToRecipients.Add("[email protected]");
item.From = new EWS.EmailAddress("", "[email protected]");
item.Body = "test";
item.Send();
}
public byte[] encry(string body, string to)
{
var store = new X509Store(StoreLocation.LocalMachine);
store.Open(OpenFlags.OpenExistingOnly | OpenFlags.ReadOnly);
X509Certificate2Collection certs = store.Certificates;
X509Certificate2 cert1 = GetMatchingCertificate(certs[1], "[email protected]", X509KeyUsageFlags.KeyEncipherment);
StringBuilder msg = new StringBuilder();
msg.AppendLine(string.Format("Content-Type: application/pkcs7-mime; smime-type=signed-data;name=smime.p7m"));
msg.AppendLine("Content-Transfer-Encoding: 7bit");
msg.AppendLine();
msg.AppendLine(body);
EnvelopedCms envelope = new EnvelopedCms(new ContentInfo(Encoding.UTF8.GetBytes(msg.ToString())));
CmsRecipient recipient = new CmsRecipient(SubjectIdentifierType.IssuerAndSerialNumber, cert1);
envelope.Encrypt(recipient);
return envelope.Encode();
}
但是还是我得到与Outlook中没有加密的纯电子邮件。我哪里出错了？
