想加密自己的软件，看过一些软件的作法，思路如下：

1、用户安装后，得出本机的机器码（硬盘的序列号，不想用网卡，因为很多机器没有网

卡）。生成机器码代码

2、用户将该机器码EMAIL给我，我用该机器码生成一个注册码，发送给用户。注册码生成

代码

3、用户在程序中输入该注册码，程序逆算该注册码，与机器码核对，查看是否相符。注册

码逆算、核对代码，

4、如果用户安装后没有得到注册码，在N天后部分功能不可用。不要太容易被改（虽然说

安装后也只有少部份功能能用）。时限功能代码，

-Would like to encrypt their own software, read the practice of some software, ideas are as follows: 1, user installation, the machines come to binary (hard drive serial number, do not want to use the card, because many machines did not card). Generate binary code 2, the user of the binary EMAIL to me, I used that to generate a binary code, send to the user. License generate code 3, users enter the key procedures, procedures inverse operator of the key, and binary check to see if the line. License inverse operator, check the code, 4, if the user did not receive registration key after installation, some features in the N days is not available. Not
