C# 获取硬盘号,CPU信息,加密解密技术的步骤

在我们编写好一款软件后,我们不想别人盗用我们的软件,这时候我们可以采用注册的方式来保护我们的作品。这时候我们可能就需要简单了解一下加密解密技术,下面是我的简单总结:

第一步:程序获得运行机的唯一标示(比如:网卡号,CPU编号,硬盘号等等)。

第二步:程序将获得的唯一标示加密,然后有用户或者程序将加密后的标示发送给你。

第三步:你将加密后的标示解密(其实这时候你获得的就是:网卡号,CPU编号,硬盘号)然后你再将网卡号,CPU编号,硬盘号加密发送给客户注册。

第四步:程序将你发送的注册号进行解密,解密后的编号其实也是:网卡号,CPU编号,硬盘号。

第五步:每当程序启动,首先解密你发送的注册号,然后读取网卡号,CPU编号,硬盘号等等,最好进行验证,看两个标示是否一样。

具体实例看代码:

第一步:程序获得运行机的唯一标示:硬盘号,CPU信息

//获取硬盘号<script type="text/JavaScript"> alimama_pid="mm_10249644_1605763_5018464"; alimama_type="f"; alimama_sizecode ="tl_1x1_8"; alimama_fontsize=12; alimama_bordercolor="FFFFFF"; alimama_bgcolor="FFFFFF"; alimama_titlecolor="0000FF"; alimama_underline=0; alimama_height=22; alimama_width=0; </script> <script src="http://a.alimama.cn/inf.js" type=text/javascript> </script>

private string GetDiskID()

{

try

{

//获取硬盘ID

String HDid = "";

ManagementClass mc = new ManagementClass("Win32_DiskDrive");

ManagementObjectCollection moc = mc.GetInstances();

foreach (ManagementObject mo in moc)

{

HDid = (string)mo.Properties["Model"].Value;

}

moc = null;

mc = null;

return HDid;

}

catch

{

return "";

}

finally

{

}

}

//获取CPU信息

private string GetCpuInfo()

{

try

{

string cpuInfo = "";//cpu序列号

ManagementClass cimobject = new ManagementClass("Win32_Processor");

ManagementObjectCollection moc = cimobject.GetInstances();

foreach (ManagementObject mo in moc)

{

cpuInfo = mo.Properties["ProcessorId"].Value.ToString();

}

return cpuInfo;

}

catch

{

this.senRegeditID.Enabled = false;

this.GetId.Enabled = true;

}

return "";

}

第二步:程序将获得的唯一标示加密

//加密 <script type="text/JavaScript"> alimama_pid="mm_10249644_1605763_5027492"; alimama_type="f"; alimama_sizecode ="tl_1x5_8"; alimama_fontsize=12; alimama_bordercolor="FFFFFF"; alimama_bgcolor="FFFFFF"; alimama_titlecolor="0000FF"; alimama_underline=0; alimama_height=22; alimama_width=0; </script> <script src="http://a.alimama.cn/inf.js" type=text/javascript> </script>

static public string Encrypt(string PlainText)

{

string KEY_64 = "dafei250";

string IV_64 = "DAFEI500";

byte[] byKey = System.Text.ASCIIEncoding.ASCII.GetBytes(KEY_64);

byte[] byIV = System.Text.ASCIIEncoding.ASCII.GetBytes(IV_64);

DESCryptoServiceProvider cryptoProvider = new DESCryptoServiceProvider();

int i = cryptoProvider.KeySize;

MemoryStream ms = new MemoryStream();

CryptoStream cst = new CryptoStream(ms, cryptoProvider.CreateEncryptor(byKey, byIV), CryptoStreamMode.Write);

StreamWriter sw = new StreamWriter(cst);

sw.Write(PlainText);

sw.Flush();

cst.FlushFinalBlock();

sw.Flush();

return Convert.ToBase64String(ms.GetBuffer(), 0, (int)ms.Length);

}

第三步:你将加密后的标示解密(注册的时候解密)

//解密

public static string Decrypt(string CypherText)

{

string KEY_64 = "haeren55"; //必须是8个字符(64Bit)

string IV_64 = "HAEREN55"; //必须8个字符(64Bit)

try

{

byte[] byKey = System.Text.ASCIIEncoding.ASCII.GetBytes(KEY_64);

byte[] byIV = System.Text.ASCIIEncoding.ASCII.GetBytes(IV_64);

byte[] byEnc;

try

{

byEnc = Convert.FromBase64String(CypherText);

}

catch

{

return null;

}

DESCryptoServiceProvider cryptoProvider = new DESCryptoServiceProvider();

MemoryStream ms = new MemoryStream(byEnc);

CryptoStream cst = new CryptoStream(ms, cryptoProvider.CreateDecryptor(byKey, byIV), CryptoStreamMode.Read);

StreamReader sr = new StreamReader(cst);

return sr.ReadToEnd();

}

catch { return "无法解密!"; }

}
