MicroCCD 4(光学处理软件) 注册简单分析
作者：HaiLDuZ[CCG Temp Member]
软件名称：MicroCCD(光学处理软件),Diffraction Limited :http://www.cyanogen.com/index.htm
整理日期：2005.12.8
文件大小：16.3MB
软件授权：收费软件
加密方式：注册码
使用工具：Ollydbg 1.10 ;W32Dasm 10.0 ；
作者申明：纯技术交流，无任何商业目的,转贴请保持完整。
前言：
前一阶段因工作需要，网上看到一个显微镜图像处理软件，注册一个演示版只有30天，结果安装一看是从他们网站注册之日起算，现在只有几天了。
看看其执行程序，没壳（老外一些商业软件比较好或对自己加密方法比较有信心），对于我这种没有脱壳能力的人太适合了。于是开始，一看是完整版，
需要注册码得到不同使用权。需事先填入姓名，邮件地址，最后期限及注册码。到其程序比较处下断。
