1，年代久远， 看着当年的课程满满回忆。课程虽然差，总觉得我就不该看了最新的课程，10 年了，大势所趋， 变化也快。
2， 看着 2003 年的 S-demo 录制的动画 其实也是一种享受。
特别路边的 D 版 hacker 杂志， 附赠的光盘，里面的破解动画。 --特喜欢，为了快乐，和没有曾经跨过去的坎， 追求，我喜欢的。不会太差。
--- 小目标， 录个 crack 的动画。
3， 一上来，这个， 08 年的 共享软件， 真的难倒我了， 看了不下 30 个小时， 虽然只有 1 小时的， 劣质动画， 但是 算法选题真的非常有水准。
;我们不用关心杂乱的运算 , 他最终赋值是这样的.
; 首先清零 ,然后初始化, 不用关心这些, 杂乱的计算, 和赋值 , 他最终的赋值 ,是这样的,
; 34 , 是用来和 邮箱这个字符串, 进行 异或运算 的,
; 54, 是用来和这个, 用户名这个字符串, 异或运算, 进行运算的.
; 异或运算以后, 接下来, 计算 ESI 的值. 如果大于 3 , 小于 等于 > 3. 那么 他就把 ESI 赋值 为 19. 否则的话, 他就会保存为 原值.
; 更具 上面两个 异或运算 已经得到的数组. 对这个 ebp + eax + 54, 和 ebp + eax + 34 再次进行异或运算. 诸位异或运算. , 并且将结果保存到, EAX + 4 这里面. 保存到上面了,
; 相当于 原来的 EAX + 4.
; 新的 eax 加 4, 大小是 20. hex. 对他的 第一 , 第 11, 再次 进行 异或运算. , 以后, 除以 ESI .
; 把值 加上 41, 保存到 , 计算的 数组里面 , 这个 注册码 里面.

; 诸位 进行 异或运算. 除以 ESI , + 41 . ;---> 这就构成一个 16 位 的 序列号.
; 这节课,内容 比较多, 运算 非常复杂, 大部分都是 异或运算, 但这些 异或运算 需要对数组 进行 识别, 对于 数组的 识别是一个 难点.
