【作者主页】:
【软件名称】: BreezeBrowser v2.13【软件大小】: 7.37 MB (7,736,182 字节)
【加壳方式】: 无壳【保护方式】: 注册码
【编写语言】: Microsoft Visual C++ 6.0【使用工具】: OD、PEID
【操作平台】: XP SP3【下载地址】: http://www.crsky.com/soft/3458.html【破解声明】: 破解在于交流思路和过程，结果并不重要，请不要用于非法用途；
【软件介绍】:BreezeBrowser是专门为佳能Powershot系列数码相机设计的图像处理程序第三方程序，支持佳能CRW文件格式，可以在进行文件格式转换时调整色阶、饱和度、白平衡等等。该软件是基于佳能开发工具SDK工作的，支持的机型有：Powershot G1、Pro90、G2、S30、S40和D30等。--------------------------------------------------------------------------------------------------------------------------------一、注册名不区分大小写黑名单：
1)、phil winegardner
2）、crsky
3）、team viroil(以这个字符串开头且注册码长度为13位)
二、字符串、万能断点、F12、API都能快速定位到关键点；三、关键点代码如下：

0054B505|.8B49 68    mov ecx,dword ptr ds:
0054B508|.E8 3714EDFF call BreezeBr.0041C944                ;算法CALL
0054B50D|.25 FF000000 and eax,0xFF
0054B512|.85C0       test eax,eax
0054B514|.74 21       je short BreezeBr.0054B537             ;关键跳转不能跳
0054B516|.6A 30       push 0x30
0054B518|.68 34A36200 push BreezeBr.0062A334                ;BreezeBrowser
0054B51D|.68 44A36200 push BreezeBr.0062A344                ;Thank you!\nYour copy of BreezeBrowser has been registered successfully。

---------------------------------------------------------------------------------------------------------------------------五、不是总结的总结：
1、这个软件有一个注册名黑名单：
2、这个软件因为是取字符串MD5后的密文中特定位置字符来来验证是否合法，因些写不了注册机；
3、这个软件的特点是算法代码很长，中间垃圾太码很多，花费的时间、精力比较多；
4、软件的注册码：注册名转小写拼接上‘+:%a@#;dj’（蓝色部分）再MD5运算大写输入，并把这个密文以’-‘分成4段每段8位，但不是每一个密文都能注册成功（对密文多次验证）；
5、算法分析难度适中，适合练手~~~~~
一组可用注册信息（试了N次才成功）：注册名：GeekCat/飘云阁注册码：CCF4E631-6E6A6007-C22CA2C3-8C7207BD---------------------------------------------------------------------------------------------------------------------------【版权声明】：本文原创于GeekCat/P.Y.G，转载请注明作者及论坛并保存文章的完整！我们都爱月姐姐

@tree_fly ，先爆破再写KG这个方案肯定没问题。
