1、写了一个小软件,用 Delphi 的 Ado,SQLServer 数据库,程序没有打包, .exe 和 数据库文件直接给了客户2、但是我不想让客户随意传播,我想对 .exe 做个加密限制,要稍微好一点的,不要注册表、ini文件之类的 例如:直接复制 .exe 到别的机器上不能用3、最好不要注册表之类的,dll 倒是可以,大家都有什么好的办法,最好能有参照的例子代码,简单的就行

.exe 启动后,我在关于窗口,同时按下 Alt+Shift+F12,会自动生成一个 key 文件,把这个 key 文件
隐藏起来放到系统下的某个位置2、 感谢一下2楼的代码:刚才 showmessage(GetIdeSerialNumber); 确实能够取出来,要是取出的硬盘id,能够写入 .exe 就好了3、不知道能否写入 .exe 文件?有可行性吗?
也可以对key进行加密,这方面的资料,可以找本《软件加密技术从入门到精通》参考下
否则可以这样试试:(我最近刚好有类似项目是这样操作的):
1、读取硬盘SN号
2、DES加密,用1中的SN号作为密钥
3、ADO连接字符串用2中的方式加密,用户名、密码等都可以参考
以上三点可通过注册程序生成到INI文件中,EXE运行读取,这样在程序中不会出现if ...then可以通过INNO做个安装程序,将有些内容隐藏起来,例注册表、关健DLL等。只能作为一般用用,如果遇到内存读取那就没办法防止了,毕竟连接字符串要解密后才能正常的。
