1.先生成公钥密钥
RSACryptoServiceProvider crypt=new RSACryptoServiceProvider();
string publickey=crypt.ToXmlString(false);//（公钥）
string privatekey=crypt.ToXmlString(true);
crypt.Clear();
StreamWriter one=new StreamWriter(@"c:\a.txt",true,UTF8Encoding.UTF8);
one.Write(publickey);
StreamWriter two=new StreamWriter(@"c:\b.txt",true,UTF8Encoding.UTF8);
two.Write(privatekey);
one.Flush();
two.Flush();
one.Close();
two.Close();
Console.WriteLine("成功保存公匙和密匙！");
2.对信息加密,然后用通过队列发送信息
string from=TextBoxFrom.Text+DropDownList2.SelectedValue;
string sub=textBoxSub.Text;
string bodys=TextBoxBody.Text;
string pwd=TextBoxPwd.Text;
StreamReader sr = new StreamReader(@"c:\a.txt",UTF8Encoding.UTF8);
string readpublickey = sr.ReadToEnd();
sr.Close();
RSACryptoServiceProvider crypt=new RSACryptoServiceProvider();
UTF8Encoding enc=new UTF8Encoding();
byte[] bytes=enc.GetBytes(pwd);
crypt.FromXmlString( readpublickey );//读取公钥
bytes = crypt.Encrypt( bytes,false ); //进行加密
string encryttext=Convert.ToBase64String(bytes); //转码
MailerInfo mf=new MailerInfo();
//mf.body=bodys;
mf.Body=bodys;
mf.From=from;
mf.Fromname=TextBoxFrom.Text;
mf.Password=encryttext;
mf.Sub=sub;
//CreateQueue(".\\myQueue");
SendMessage(mf);
}
public static void CreateQueue(string queuePath)
{
try
{
if(!MessageQueue.Exists(queuePath))
{
MessageQueue.Create(@".\private$\myQueue");
}
else
{
Console.WriteLine(queuePath + " already exists.");
}
}
catch (MessageQueueException e)
{
Console.WriteLine(e.Message);
}
}
public void SendMessage(MailerInfo mf)
{
try
{
MessageQueue myQueue = new MessageQueue(".\\private$\\myQueue");
System.Messaging.Message myMessage = new System.Messaging.Message(mf);
myQueue.Send(myMessage);
}
catch(ArgumentException e)
{
Console.WriteLine(e.Message);
}
return;
}
3.在服务器端独立运行程序,在队列里面读取信息
public void ReceiveMessage()
{
MessageQueue myQueue = new MessageQueue(".\\private$\\myQueue");
myQueue.Formatter = new XmlMessageFormatter(new Type[]{typeof(MessageRec.MailerInfo)});
try
{
System.Messaging.Message myMessage = myQueue.Receive();
MailerInfo mf = (MailerInfo)myMessage.Body;
//解码
StreamReader sr = new StreamReader(@"c:\b.txt",UTF8Encoding.UTF8);
string readprivatekey = sr.ReadToEnd();
sr.Close();
RSACryptoServiceProvider crypt=new RSACryptoServiceProvider();
UTF8Encoding enc=new UTF8Encoding();
byte[] bytes = Convert.FromBase64String(mf.password);
crypt.FromXmlString ( readprivatekey ) ;
byte[] decryptbyte = crypt.Decrypt( bytes,false );
password=enc.GetString( decryptbyte );
from=mf.from;
fromname=mf.Fromname;
sub=mf.sub;
body=mf.body;
to="dankes@163.com";
}
catch (MessageQueueException)
{
}
catch (InvalidOperationException e)
{
Console.WriteLine(e.Message);
}
//发送邮件
jmail.Message Jmail=new jmail.Message();
Jmail.Silent=false;
Jmail.Logging=true;
Jmail.Charset="GB2312";
Jmail.ContentType="text/html";
Jmail.AddRecipient(to,"","");
Jmail.From=from;
Jmail.MailServerUserName=fromname;
Jmail.MailServerPassWord=password;
Jmail.Subject=sub;
Jmail.Body=body;
string smtp="smtp.163.com";
if(from.EndsWith("tom.com"))
{
smtp="smtp.tom.com";
}
else if(from.EndsWith("21cn.com"))
{
smtp="smtp.21cn.com";
}
else if(from.EndsWith("sina.com"))
{
smtp="smtp.sina.com";
}
else if(from.EndsWith("263.com"))
{
smtp="smtp.263.com";
}
//开始发送邮件
int i=0;
try
{
Jmail.Send(smtp,false);
}
catch(Exception ee)
{
i=1;
}
Jmail.Close() ;
if(i==0)
Console.WriteLine("邮件发送成功"+"发送人:"+from+"接收方:"+to+"主题是:"+sub);
if(i==1)
Console.WriteLine("登陆失败，或者网络故障");
}
