软件EXE文件的CRC校验号码?什么东西,怎么获取?

要求这么高,我看不如用加密狗。
 
to linx:
即通过对文件的CRC32算法取得一个唯一不变的值,每个文件的CRC值都不一样,就是同样的源代码
重新编译过都会不同,WINRAR中就用CRC算法来判断文件是否被破坏.
取得办法也很简单,网上有源代码,你找找看,另外,这种源代码还可以加到你的程序中,通过对自
身的检测来判断文件是否被修改过,这可是防破解的一道利器,
 
to 大梦:
老兄,你不要老说风凉话好不好?!不要在我的贴子里灌水!
  我对软件做加密,并不指望不可能被人破解,但如有位老兄所说,别人破解不了我的
售后服务。我的软件并非做给专业或准专业人士所用,只想在一定范围内起到保护作用,
但起码不是形同虚设的。
  你说我要求高,我怀疑你有没了解过共享软件的加密?现在很多的共享软件都采用这
样机器码到注册码的方式,实现也不过如此。
  你说用加密狗,有没搞错,一个百来块钱的软件用加密狗,我看你是搞“公益事业”
的!
  看看你“大梦”的资料,都回答了些什么问题。
  拜托,如果不会回答,就像很多兄弟们一样“UP”或“学习”就好,做人谦虚一点儿
。如果会回答,就拿出高手的本事来,抄抄贴贴也没关系,互相帮助大富翁才会兴旺。
  说实话,开这些贴子,一是为了急用,二是为了好好学习大家这方面的经验,三是让
想了解这方面的朋友们一起来学习。
 
另外向回答和参与问题的DFW们表示感谢!
 
高手论道,我辈自当洗耳恭听!

请问高手这是什么意思,怎么用呀.还有那个crc的算法的注释能不能在详点,谢谢!
 
哇!这么多朋友讨论
为表谢意,我决定讨论结束后,再开一个300分的贴子给以上参加讨论的DFW们。
准备在一周内结束。请DFW们积极发言,谢谢!
 
收益非浅,我也正想找着方面的资料!!
 
如果出现 'The stylesheet dose not contain a document element.
The stylesheet maybe empty, or it may not be a well- formated XML
document.'错误。

这是一个因为网络连接问题引起的暂时性的错误,请 按这里。选择一个
界面重新进入即可。
我有一个星期都是这样了,有人能帮我吗?
点“按这里”也没有用,但是点击以前回复的可以进来,就是看不到
我(左边的)自己的信息.
yanghai0437@sina.com
 
也正在为此问题发愁
谢谢
