首先赞一下xyz_119兄这个CrackMe做的十分的好，花了我两个晚上才破掉。
【分析】
算法用到了一种类似于DES的加密算法，和RSA大数运算，还有两种未知的加密算法unknown1,unknown2。
一种unknown1是把16 BYTE <=> (A)8 BYTE (B)8 BYTE，这16BYTE是注册码，8 BYTE A是类DES的明文,B是类DES的密钥，是可逆的运算。
一种unknown2是4BYTE 明密文 4BYTE 密钥的加密算法，算法皆未知。主要是用于程序启动后的验证工作，是用上面的B的前4位做密钥，加密后四位，看看加密后的密文是不是0x78,0x79,0x7A,0x00，也就是("xyz")。
好，Let's Begin!

发现这两段惊人的对称，呵呵，后面会有更多的好奇的地方。用IDA抓下代码生成，写一段程序进行验证，果真是unknown1的逆函数。好先留着
。
我把这两个函数叫做：
void _stdcall sub_serail_trans(serial,key,plain); //serial key plain
void _stdcall sub_trans_serial(key,plain,serial); //key plain serial
[类DES part]
进入类DES的加密，为什么叫它类DES的加密算法，请听我慢慢道来。

去掉头个字节，变成BA D9 BA D9 B2 BB B4 ED 00 (是汉字"嘿嘿不错")，呵呵，xyz兄好逗。
第一步的破击方法
类Des解密(BA D9 BA D9 B2 BB B4 ED)=>8 BYTE 明文
再有Key和明文生成 =>Serial
由于这里Key具有任意性，我选择了nightfox 变换"nigh"|0x11000000=>nigy nigyfox 呵呵
用注册机验证，Serial:DCB461-963736-419D10-951616-F514E2-1F

还想用ida抓下来，发现涉及的CALL太多，太烦了，于是做起狸猫换太子的勾当。由于加密和解密函数的参数一致性。
00402080 . 50 push eax ; //cipher保存地址
00402081 . 6A 04 push 4 //size=4
00402083 . 8B55 48 mov edx, [ebp+48]
00402086 . 8D4D 4C lea ecx, [ebp+4C]
00402089 . 51 push ecx //plain
0040208A . 52 push edx //key
0040208B . C64424 1B 00 mov byte ptr [esp+1B], 0
00402090 E8 6BE60000 call 00410700 ; call 4105F0 关键CALL
改写00402090代码，换成
00402080 . 50 push eax ; //plain保存地址
00402081 . 6A 04 push 4 //size=4
00402083 . 8B55 48 mov edx, [ebp+48]
00402086 . 8D4D 4C lea ecx, [ebp+4C]
00402089 . 51 push ecx //cipher
0040208A . 52 push edx //key
0040208B . C64424 1B 00 mov byte ptr [esp+1B], 0
00402090 E8 6BE60000 call 4105F0 ; call 4105F0 关键CALL
然后写改加密内容
d ecx 修改成为
0045C3DC 78 79 7A 00 xyz.
运行后，原先地址eax里面就是解密(78 79 7A 00)的明文了。
由于这里的key的随意性，我用了0xBBE5F13E，当然0xBBE5F13E&0x11000000!=0，为什么见前面。
解密的结果是0xB6,0xDD,0x15,0x0E，所以我最早的
B是类DES的密钥={0x3E,0xF1,0xE5,0xBB,0xB6,0xDD,0x15,0x0E};
通过计算得到
A是类DES的明文=类Des解密(BA D9 BA D9 B2 BB B4 ED)=>8 BYTE 明文={42 38 DE AE B8 2F 4D 9C}
再通过unknown1的逆函数得到serial:5C2581-5FB9F6-EDCD94-CFFB59-B321F4-82
【总结】
这个CrackMe很好，玩起来很舒服。谢谢xyz_119兄，也谢谢看到这里的你。
注册机源代码见附件。用到C++/ASM混编。
