C\# 伪证书加密技术，大家看到这个标题可能很惊讶 是的，我把，过期时间，机器码都存到文件里去了，然后在程序里调用。

**生成证书**

![QQ_E6_88_AA_E5_9B_BE_E6_9C_AA_E5_91_BD_E5_90_8D.jpg][]这个是 ![15.jpg][]生成的证书。

生成证书代码：

///  <summary>   
 ///  生成证书，并保存到指定位置，默认保存在当前用户桌面  
 ///  </summary>   
  public  void  CreatePfxFile( string  SavePaht)  
\{  
 if  (McieCode.Length  ==  0 )\{  
McieCode  =  MachineCode.GetCpuInfo();  
\}  
StringBuilder builder  =  new  StringBuilder();  
builder.AppendLine( " <?xml version=\\"1.0\\" encoding=\\"utf-8\\" ?> " );  
builder.AppendLine( " <root> " );  
builder.AppendLine( "  <guid> "  \+  Guid  \+  " </guid> " );  
builder.AppendLine( "  <name> "  \+  Name  \+  " </name> " );  
builder.AppendLine( "  <address> "  \+  Address  \+  " </address> " );  
builder.AppendLine( "  <phone> "  \+  Phone  \+  " </phone> " );  
builder.AppendLine( "  <postalcode> "  \+  Postalcode  \+  " </postalcode> " );  
builder.AppendLine( "  <machinecode> "  \+  McieCode  \+  " </machinecode> " );  
builder.AppendLine( "  <deadline> "  \+  Deadline  \+  " </deadline> " );  
builder.AppendLine( " </root> " );  
  
 string  des  =  DESEncrypt.Encode(builder.ToString());  
 if  (SavePaht.Length  ==  0 )  
\{  
 string  desktop  =  Environment.GetFolderPath(Environment.SpecialFolder.Desktop);  
SavePaht  =  desktop  \+  " \\\\SoftDog.pfx " ;  
\}  
StreamWriter sw  =  File.AppendText(SavePaht);  
sw.WriteLine(des);  
sw.Flush();  
sw.Close();  
\}

**证书管理**

![23.jpg][]

**使用证书**

证书使用步骤：

1：将生成的证书 ![15.jpg][]文件复制到系统目录下的system32文件夹下。

2：将 SoftDog.IsDogDalne(); 写到你的WEB项目否WIN项目里就可以使用证书了。

生成序列号：

1111-1100-0000-008y

代码如下：

private  string  CreateRandomNum()  
\{  
 string  result  =  "" ;  
 \#region  生成随机号   
 for  ( int  i  =  0 ; i  <  16 ; i \++ )  
\{  
Random myRandom1  =  new  Random(( int )DateTime.Now.Ticks);  
System.Threading.Thread.Sleep( 1 );  
 int  kinds  =  myRandom1.Next( 0 ,  3 );  
 switch  (kinds)  
\{  
 case  0 : // 数字类   
  \#region  数字   
Random myRandom11  =  new  Random(( int )DateTime.Now.Ticks);  
System.Threading.Thread.Sleep( 1 );  
 int  number11  =  myRandom11.Next( 0 ,  9 );  
result  \+=  number11.ToString();  
 continue ;  
 \#endregion   
 case  1 : // 大写字母类   
  \#region  大写字母类   
Random myRandom22  =  new  Random(( int )DateTime.Now.Ticks);  
System.Threading.Thread.Sleep( 1 );  
 int  number22  =  myRandom22.Next( 65 ,  90 );  
result  \+=  Convert.ToChar(number22).ToString();  
 continue ;  
 \#endregion   
 case  2 : // 小写字母类   
  \#region  小写字母类   
Random myRandom33  =  new  Random(( int )DateTime.Now.Ticks);  
System.Threading.Thread.Sleep( 1 );  
 int  number33  =  myRandom33.Next( 97 ,  122 );  
result  \+=  Convert.ToChar(number33).ToString();  
 continue ;  
 \#endregion   
 default :  break ;  
\}  
\}  
 \#endregion   
 \#region  加"-"   
 string  newstring = "" ;  
 for  ( int  i  =  1 ; i  <=  result.Length; i \++ )  
\{  
newstring \+= result\[i \- 1 \];  
 if  (i  %  4  ==  0  &&  i  !=  result.Length)  
newstring  \+=  " \- " ;  
\}  
result  =  newstring;  
 \#endregion   
 return  result;  
\}
