【文章作者】: 网络断魂
【软件名称】: 自己猜猜
【下载地址】: http://***.okeyoa.cn/
【加壳方式】: 无壳
【保护方式】: key文件保护（机器码+用户数量+DES算法）
【编写语言】: Borland Delphi 6.0 - 7.0
【使用工具】: OD，PEID，PYG密码学综合工具
【操作平台】: winxp2
【作者声明】: 也不知道分析的对不对，大家别笑话偶
1、软件概貌：
1）、软件所有提示字符串全部经DES算法加密（标准DES算法，密钥：windows），密钥及加密后的字符串可在OD中找到
2）、申请注册时需填入“公司名称”、“用户数量”，生成一个正版用户认证文件，内容全部是十六进制字符串（标准DES算法，密钥：officeim），密钥及加密后在字符串可以在生成UID文件时下断找到，
3）、用户需从厂家拿到一个licence.id的KEY文件才能完成注册，文件内容全部是十六进制字符串，软件打开时会载入KEY文件进行较验（标准DES算法，密钥：daily（全文解密）、windows（机器码部份）），密钥及加密后的内容可以OD中找到，
以下是参考的解密内容：
正版用户认证文件（天津市大港区民政局.uid）加密算法：标准DES 密钥：officeim
申请注册时产生的正版用户认证文件内容：

4、算法总结：
officeim
用户公司名
用户数量的数字
注册时间（例如：2007-12-13）
officeim_机器码经DES加密（密钥：windows)
F11
F21
F31
F41
F51
F61
F71
F81
以上内容经DES加密后得到的结果作为最终KEY文件内容，其中用户公司名，用户数量，注册时间，机器码是由用户发送的UID文件解密后得到，F11等固定值取决于用户生成UID文件时选择的功能，
【软件名称】: 自己猜猜
【下载地址】: http://***.okeyoa.cn/
【加壳方式】: 无壳
【保护方式】: key文件保护（机器码+用户数量+DES算法）
【编写语言】: Borland Delphi 6.0 - 7.0
【使用工具】: OD，PEID，PYG密码学综合工具
【操作平台】: winxp2
【作者声明】: 也不知道分析的对不对，大家别笑话偶
1、软件概貌：
1）、软件所有提示字符串全部经DES算法加密（标准DES算法，密钥：windows），密钥及加密后的字符串可在OD中找到
2）、申请注册时需填入“公司名称”、“用户数量”，生成一个正版用户认证文件，内容全部是十六进制字符串（标准DES算法，密钥：officeim），密钥及加密后在字符串可以在生成UID文件时下断找到，
3）、用户需从厂家拿到一个licence.id的KEY文件才能完成注册，文件内容全部是十六进制字符串，软件打开时会载入KEY文件进行较验（标准DES算法，密钥：daily（全文解密）、windows（机器码部份）），密钥及加密后的内容可以OD中找到，
以下是参考的解密内容：

4、算法总结：
officeim
用户公司名
用户数量的数字
注册时间（例如：2007-12-13）
officeim_机器码经DES加密（密钥：windows)
F11
F21
F31
F41
F51
F61
F71
F81
以上内容经DES加密后得到的结果作为最终KEY文件内容，其中用户公司名，用户数量，注册时间，机器码是由用户发送的UID文件解密后得到，F11等固定值取决于用户生成UID文件时选择的功能，
