分享求助，用c#写了一个小程序，怎么给它加密，实现一机一码！
用c#写了一个小程序，怎么给它加密，实现一机一码！
就是让别人用的时候需要在他的电脑注册，注册的时候需要我这边生成注册码。不能再别的机器上使用！

随便找个能表示对面机子的唯一标识，简单加下密（比如MD5)就行了

注册码 自己写个算法就行了 可以参考2楼

查下 Xenocode

你的程序获取对方主机的硬盘序列号或cpu等序列号，然后根据这个序列号你在加密等处理一下生成一个串，你再根据这个串生成一个注册码。
用户用这个注册码注册时，要根据主机的硬件序列号来匹配，一致才可以注册，不一致不能注册。
这样这个注册码就只能在此机器上注册了。
至于怎么获取硬盘等硬件序列号，给你一个类参考一下：

using System.Runtime.InteropServices;
using System.Management;

{

ManagementObjectCollection moc = mc.GetInstances();
string strCpuID = null ;
foreach( ManagementObject mo in moc )
{
strCpuID = mo.Properties["ProcessorId"].Value.ToString();
break;
}
return strCpuID;
}
