**************************************************************
一、运行程序,进行注册,输入错误的注册信息进行检测,有提示信息
"registration code is invalid!"
**************************************************************
二、用PEiD对这个软件查壳,为 Borland Delphi 6.0 - 7.0
**************************************************************
三、运行OD,打开mailer,用F12暂停法,来到关键之处- 005E2214 /$ 55 PUSH EBP

【破解总结】
和固定注册码差不多,适合像我这样的小菜鸟练习
--------------------------------------------------------------
【算法总结】
1、注册码长度为14
2、注册码第1位必须为"1";第3位必须为"9";第4位必须为"3";第5位必须为"5";第8位必须为"9";第9位必须为"4";第11位必须为"0"
--------------------------------------------------------------
【算法注册机】
Private Sub Command1_Click()
Dim a1, a2, a3, a4, a5, a6, a7
a1 = Int(Rnd() * 10)
a2 = Int(Rnd() * 10)
a3 = Int(Rnd() * 10)
a4 = Int(Rnd() * 10)
a5 = Int(Rnd() * 10)
a6 = Int(Rnd() * 10)
a7 = Int(Rnd() * 10)
Text1.Text = "1" & a1 & "9" & "3" & "5" & a2 & a3 & "9" & "4" & a4 & "0" & a5 & a6 & a7
End Sub
--------------------------------------------------------------
【注册信息】
注册码:1*935**94*0*** (星号任意)
