破解过程：
1、dnspy加载FastBrowserCleaner.exe，浏览下软件代码结构，注册接口位置很明显（frmRegister窗口类）；
2、进入注册接口；
注册接口代码如下：
private void btnRegisterNow_Click(object sender, EventArgs e)
{
try
{
if (string.IsNullOrEmpty(this.txtKey.Text))
{
MessageBox.Show(Resources.Register_EnterKey, Program.sApplicationName, MessageBoxButtons.OK, MessageBoxIcon.Asterisk);
}
else
{
string empty = string.Empty;
int num = Program.RegisterVerify(this.txtKey.Text, out empty);
if (num == 0)
{
this.SaveInRegistry();
}
Program.oFrmMain.SetRegistrationState();
MessageBox.Show(empty, Program.sApplicationName, MessageBoxButtons.OK, MessageBoxIcon.Asterisk);
if (num == 0)
{
base.Close();
}
}
}
catch (Exception ex)
{
Program.oErrorLog.Write("btnRegisterNow_Click", ex.Message, "frmRegister");
}
}
2、进入注册接口，关键位置继续跟进//int num = Program.RegisterVerify(this.txtKey.Text, out empty);
public static int RegisterVerify(string sKey, out string sMessage)
{
return Program.RegisterVerify(sKey, out sMessage, false);
}
public static int RegisterVerify(string sKey, out string sMessage, bool bOnlyVerify)
{
int num = -1;
sMessage = Program.GetEnumDescription(WebExceptionStatus.Timeout);
Program.bRegistered = false;
try
{
string combinedUserId = Program.GetCombinedUserId(bOnlyVerify);
string arg = string.Format(combinedUserId, ",");
string arg2 = string.Format(combinedUserId, "|");
DateTime value = new DateTime(2013, 7, 10);
Program.sActivationDate = DateTime.Now.Date.Subtract(value).TotalDays.ToString();
string requestUriString = "http://www.fastpctools.com/fbc/Register.php";
if (bOnlyVerify)
{
requestUriString = "http://www.fastpctools.com/fbc/Verify.php";
}
string text = string.Format("val1={0}", sKey);
string text2 = string.Format("val2={0}", Program.sActivationDate);
string text3 = string.Format("val3={0}", arg);
string text4 = string.Format("val4={0}", arg2);
string text5 = string.Concat(new string[]
{
"&",
text,
"&",
text2,
"&",
text3,
"&",
text4
});
WebRequest webRequest = WebRequest.Create(requestUriString);
webRequest.Method = "POST";
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.ContentLength = (long)text5.Length;
using (StreamWriter streamWriter = new StreamWriter(webRequest.GetRequestStream()))
{
streamWriter.Write(text5);
}
WebResponse response = webRequest.GetResponse();
StreamReader streamReader = new StreamReader(response.GetResponseStream());
string text6 = streamReader.ReadToEnd();
//text6为网络返回数据，只需按照后面的数据需求构建返回值即可，此处强行插入text6 = "0000000,00000365,0000020990101";，具体为什么(365--注册起始日期跟2013年7月10日天数差，20990101为有效日期)
response.Close();
webRequest = null;
if (!string.IsNullOrEmpty(text6))
{
string[] array = text6.Split(new string[]
{
","
}, StringSplitOptions.None);
if (array.Length > 2)
{
Program.bKeyChecked = true;
string text7 = array;
if (!string.IsNullOrEmpty(text7) && text7.Length > 5)
{
text7 = text7.Substring(5);
num = Convert.ToInt32(text7);
}
Program.bRegistered = false;
if (num == 0)
{
Program.sRegistrationKey = sKey;
text7 = array;
if (!string.IsNullOrEmpty(text7) && text7.Length > 5)
{
text7 = text7.Substring(5);
Program.sActivationDate = text7;
}
text7 = array;
if (!string.IsNullOrEmpty(text7) && text7.Length > 5)
{
text7 = text7.Substring(5);
Program.nValidDays = Convert.ToInt32(text7);
}
Program.sMyUniID = Program.sMyTempUniID;
Program.bRegistered = true;
}
switch (num)
{
case -1:
case 5:
sMessage = Resources.Main_UnKnownError;
break;
case 0:
sMessage = string.Format(Resources.Main_RegisteredSuccessfully, Application.ProductName);
break;
case 1:
sMessage = Resources.Main_InvalidKey;
break;
case 2:
sMessage = Resources.Main_KeyAlreadyUsed;
break;
case 3:
sMessage = Resources.Main_KeyBlocked;
Program.CleanRegistry();
break;
case 4:
sMessage = Resources.Main_KeyExpired;
break;
case 6:
sMessage = Resources.Main_UnauthorizedUser;
break;
case 7:
sMessage = Resources.Main_InvalidactivationDate;
break;
}
}
}
}
catch (WebException ex)
{
sMessage = Resources.Main_UnKnownError;
switch (ex.Status)
{
case WebExceptionStatus.NameResolutionFailure:
case WebExceptionStatus.ConnectFailure:
case WebExceptionStatus.ReceiveFailure:
case WebExceptionStatus.SendFailure:
sMessage = Resources.Main_CouldNotConnectServer;
break;
}
Program.oErrorLog.Write("RegisterVerify", sMessage, "Program");
}
catch (Exception)
{
sMessage = Resources.Main_UnKnownError;
Program.oErrorLog.Write("RegisterVerify", sMessage, "Program");
}
return num;
}
3、定位到修改位置点，即网络接口返回数据后，强制将返回值赋值成软件所需要的值；
4、保存修改；
破解前后展示：
破解文件就不提供了，表哥们动手解决吧。
