MonoTouch 二三事（二）

2013-02-26 更新 真機秒退問題，授權檔案格式原來的不對。
接上篇。
把client.exe拖入ilspy後發現，授權是靠mac地址+磁碟序列號等資訊，授權驗證依賴了rsa簽名，得了，咱沒超級計算機，跑不出對應的私鑰，只有直接該程式碼爆破了。
但是在改制前呢？我大概瀏覽了下client.exe的功能，並沒有發現有關各種安裝的相關程式碼，也就是說這個東西他只負責驗證授權資訊，並儲存成授權檔案到~/Library/MonoTouch/License.v2，驗證授權成功就可以安裝，驗證授權失敗那就停止安裝。與把程式安裝到哪兒，怎麼安裝並沒有任何關係，那我們何不直接越過這個步驟呢？
別忘了他只是個安裝前執行的指令碼~
因為他是個PackageMaker製作的安裝包，並不能直接刪除我們要刪除的preinstall這個指令碼，那我們直接看monotouch.pkg裡面的PackageInfo檔案，
<pkg-info format-version="2" identifier="com.xamarin.monotouch.pkg" version="1" install-location="/Developer/MonoTouch" auth="root"> <payload installKBytes="254496" numberOfFiles="4425"/> <scripts> <preinstall file="./preinstall"/> <postinstall file="./postinstall"/> </scripts> </pkg-info>
一種方法是直接刪除<preinstall file="./preinstall"/>這句，然後再次用PackageMaker打包，嗯，自從XCODE4.*以後這個打包工具從XCODE裡面被Apple給移除了，想用的話得自己下載安裝，我到下載頁面用IE說什麼也下載不下來，chrome倒是下載下來了，2KB。。。不下了。直接按照上面那個XML檔案所給的安裝位置，建立好目錄
/Developer/MonoTouch
（注意這個目錄在之前版本是安裝XCODE後自動建立的，並且XCODE等開發工具也安裝到此目錄，但新版XCODE會直接安裝到/Application/Xcode.app,導致此目錄我們得手動建立）
並拷貝上文提到的Payload解壓後備用的檔案到其下，然後把postinstall這個安裝後執行檔案也拷貝到這個目錄下，然後在終端下執行postinstall，OK，安裝好了，
執行我們之前裝的MonoDevelop，新建一個iPhone專案，編譯模擬器版Debug，會發現如下圖
無授權哦，看看是/Developer/MonoTouch/usr/bin/mtouch這個程式有問題，會驗證授權。這個是mkbundle打包的，用之前的方法提取其託管程式集
我們得到一堆程式集，其中被我選中那幾個是關鍵程式集，其他的都是Mono程式集，把mtouch.exe拖入ilspy，搜尋Main方法，這時找到如下圖的類
Main在我選中的類裡面，這個程式集比較奇怪，Main在一個internal class MTouch裡面，我們看看他的驗證過程
Main呼叫了Main2
Main2裡關於驗證的是
View Code
bool show_help = false; bool show_version = false; bool generate_manifests = true; List<string> list2 = new List<string>(); List<string> references = new List<string>(); List<MTouch.Resource> res = new List<MTouch.Resource>(); string user_gcc_flags = null; string device_name = null; try { Activation activation = new Activation(Certificates.Server, Certificates.Client, null); License license = License.LoadFromFile(activation.Crypto, Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Personal), "Library/MonoTouch/License.v2")); if (Sys.Serial == null) { Console.Error.WriteLine("Invalid license. Please contact [email protected]"); Environment.Exit(97); } MTouch.ComputeHashes(Sys.Serial, Sys.Mac); for (int i = 0; i < license.UserData.H1.Length; i++) { if (MTouch.H1[i] != license.UserData.H1[i]) { throw new Exception(); } } for (int j = 0; j < license.UserData.H2.Length; j++) { if (MTouch.H2[j] != license.UserData.H2[j]) { throw new Exception(); } } for (int k = 0; k < license.UserData.H3.Length; k++) { if (MTouch.H3[k] != license.UserData.H3[k]) { throw new Exception(); } } if (license.UserData.ProductVersion < 5) { throw new Exception(); } } catch (FileNotFoundException) { Console.Error.WriteLine("License file is missing. Please activate MonoTouch"); Environment.Exit(98); } catch (DirectoryNotFoundException) { Console.Error.WriteLine("License file is missing. Please activate MonoTouch"); Environment.Exit(98); } catch (Exception value) { Console.Error.WriteLine("Invalid license. Please reactivate MonoTouch"); if (MTouch.verbose > 2) { Console.WriteLine(value); } Environment.Exit(99); }
這下該修改程式集了，取消驗證那段程式碼，得請出Reflector + reflexil.1.5外掛
去掉相關li程式碼，並保持託管堆疊的平衡，也就是不用想原來的push和pop，然後另存為新程式集，再次開啟
授權相關程式碼消失了。。嘎嘎
把所有解壓的程式集包括[處理]後的mtouch.exe（除去Mono自帶的系統程式集，需要哪個不需要哪個可以執行起來試試能不能執行），複製到
/Developer/MonoTouch/usr/bin/
這個目錄，最終我複製了
Mono.Cecil.dll
Mono.Cecil.Mdb.dll
Mono.Touch.Client.dll
Mono.Touch.Common.dll
monotouch.dll
MonoTouch.Linker.dll
[處理]後的 mtouch.exe
到/Developer/MonoTouch/usr/bin/
因為MonoDevelop.IPhone這個MonoDevelop外掛在專案編譯時呼叫的是沒有exe字尾的那個打包後的Mac原生程式，得讓他執行我們的exe，在
/Developer/MonoTouch/usr/bin/
建立名為mtouch的bash指令碼，替代原來的mtouch，內容如下：
#!/bin/sh # by BinSsy DIR=$(cd "$(dirname "$0")"; pwd) MONO_FRAMEWORK_PATH=/Library/Frameworks/Mono.framework/Versions/Current export DYLD_FALLBACK_LIBRARY_PATH="$DIR:$MONO_FRAMEWORK_PATH/lib:/lib:/usr/lib" export PATH="$MONO_FRAMEWORK_PATH/bin:$PATH" #Start mtouch.exe with args mono "$DIR/mtouch.exe" "[email protected]"
ok再次編譯通過，現在我們改成非模擬器編譯，報錯
No valid iPhone code signing keys found in keychain.
看來涉及簽名啊，最終通過檢視MonoDevelop.IPhone這個外掛程式碼，發現成功編譯需要有開發者證書這個證書的名稱必須類似是
iPhone Developer: BinSys (822ED3R5M7)
還有一個放在路徑 ~/Library/MobileDevice/Provisioning Profiles/ 裡面的以.mobileprovision結尾的裝置預置配置檔案。這個檔案是個pkcs#7訊息信封，
被蘋果一個證書籤名的，具體格式資訊是在

這個檔案正規來說是從Apple的開發者計劃的頁面下載的，但我現在沒有開發者帳號，所以自己產生一個，包上面xml儲存成utf8編碼的xml檔案，然後下面程式碼：
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; using System.Security.Cryptography.Pkcs; using System.Security.Cryptography.X509Certificates; using MonoDevelop.MacDev.Plist; using System.Xml; namespace makemp { class Program { static void Main(string[] args) { //從MAC匯出的證書檔案 和匯出時設定的密碼 X509Certificate2 signgercert = new X509Certificate2(@"my.p12", "*****"); PlistDocument pd = new PlistDocument(); //模版檔案 pd.LoadFromXmlFile(@"mobileprovision_Template.xml"); //ApplicationIdentifierPrefix PlistDictionary root_dic = pd.Root as PlistDictionary; //PlistArray ApplicationIdentifierPrefix_s = root_dic["ApplicationIdentifierPrefix"] as PlistArray; //PlistString ApplicationIdentifierPrefix_1 = ApplicationIdentifierPrefix_s.Value.FirstOrDefault() as PlistString; //ApplicationIdentifierPrefix_1.Value = "123456789"; //CreationDate PlistDate CreationDate = root_dic["CreationDate"] as PlistDate; CreationDate.Value = DateTime.Now; //DeveloperCertificates PlistArray DeveloperCertificates_s = root_dic["DeveloperCertificates"] as PlistArray; PlistData DeveloperCertificates_1 = DeveloperCertificates_s.Value.FirstOrDefault() as PlistData; DeveloperCertificates_1.Value = signgercert.Export(X509ContentType.Cert); //Entitlements //ExpirationDate PlistDate ExpirationDate = root_dic["ExpirationDate"] as PlistDate; ExpirationDate.Value = DateTime.Now.AddYears(10); //Name PlistString Name = root_dic["Name"] as PlistString; Name.Value = "TestApp"; //ProvisionedDevices PlistArray ProvisionedDevices_s = root_dic["ProvisionedDevices"] as PlistArray; PlistString ProvisionedDevices_1 = ProvisionedDevices_s.Value.FirstOrDefault() as PlistString; ProvisionedDevices_1.Value = "e5fb5e41110b57ad370e0725610b7a9ba31df40e"; //UUID PlistString UUID = root_dic["UUID"] as PlistString; UUID.Value = Guid.NewGuid().ToString().ToUpper(); //pd.WriteToFile("aa.xml"); MemoryStream ms = new MemoryStream(); using (XmlTextWriter xmlTextWriter = new XmlTextWriter(ms, UpperCaseUTF8Encoding.UpperCaseUTF8)) { xmlTextWriter.Indentation = 1; xmlTextWriter.IndentChar = '\t'; xmlTextWriter.Formatting = Formatting.Indented; pd.Write(xmlTextWriter); } File.WriteAllBytes("my.mobileprovision", Encode(Encoding.UTF8.GetString(ms.GetBuffer()), signgercert)); } static string Decode(byte[] bytes) { SignedCms sc = new SignedCms(); sc.Decode(bytes); //foreach (X509Certificate2 cert in sc.Certificates) //{ // Console.WriteLine(cert.Thumbprint); // File.WriteAllBytes(string.Format("Thumbprint_{0}.cer", cert.Thumbprint), cert.Export(X509ContentType.Cert)); //} return Encoding.UTF8.GetString(sc.ContentInfo.Content); } static byte[] Encode(string source, X509Certificate2 cert) { byte[] sourceBytes = Encoding.UTF8.GetBytes(source); CmsSigner cs = new CmsSigner(cert); cs.IncludeOption = X509IncludeOption.WholeChain; ContentInfo ci = new ContentInfo(sourceBytes); SignedCms sc2 = new SignedCms(ci, false); sc2.ComputeSignature(cs); return sc2.Encode(); } } }
詳細程式碼本文後邊有打包。那個證書是從mac匯出的。
這樣生成了與我們自己的開發者證書想對應的.mobileprovision檔案，把他放到
~/Library/MobileDevice/Provisioning Profiles/
目錄裡。

編譯出錯。估計拉下哪個檔案沒[處理]，看MonoDevelop.IPhone程式碼，可以知道其根據編譯引數呼叫了/Developer/MonoTouch/usr/bin/目錄下的arm-darwin-mono和arm-darwin-mono-sgen這兩個原生蘋果程式。全是Native程式碼，沒發現什麼經過打包的痕跡。
嗯，因為看編譯選項發現我們沒有選中sgen這個垃圾回收器，所以這此編譯呼叫的應該是arm-darwin-mono這個AOT編譯器，用IDA開啟等待分析完畢（檔案大，有點兒慢）
發現驗證授權時打開了~/Library/MonoTouch/License.v2 這個檔案，看了下，也是驗證了RSA sha1簽名，我們通過把三個在破解領域爆破方法裡的關鍵跳jnz改成nop，（arm-darwin-mono-sgen 同樣處理）並偽造一個特定格式的 License.v2檔案，這個格式是一個全0的二進位制檔案，長度為60+N+1+128，60位元組是三個長度為20的hash，N任意，1為一個特定值，必須大於1，後邊128位元組為一個二進位制檔案被1024位rsa key用sha1演算法簽名後產生的簽名指紋的資料長度，128位元組，我麼寫全0吧。這樣把這個檔案放到指定目錄，把在windows裡修改過的兩個程式放到mac替換原來的，編譯。。。。。各種通過，各種ipa都產生了，剩下的就是把ipa放到越獄的裝置裡了，進行效能測試。
這個授權檔案格式如下：
View Code
string IOPlatformSerialNumber = "VMWVk3P/wPmJkRIwb5ycu1EQw"; string IOMACAddress = "00:0c:29:ed:44:43"; GetLicense(Salt, IOPlatformSerialNumber, IOMACAddress); private static void GetLicense(byte[] salt, string IOPlatformSerialNumber, string IOMACAddress) { byte[] IOPlatformSerialNumber_Bytes = System.Text.Encoding.UTF8.GetBytes(IOPlatformSerialNumber); byte[] IOMACAddress_Bytes = System.Text.Encoding.UTF8.GetBytes(IOMACAddress); System.IO.MemoryStream ms = new System.IO.MemoryStream(IOPlatformSerialNumber_Bytes.Length + IOMACAddress_Bytes.Length + salt.Length); System.Security.Cryptography.HashAlgorithm alg = System.Security.Cryptography.SHA1.Create(); byte[] hash1 = GetHash(alg, ms, IOPlatformSerialNumber_Bytes, IOMACAddress_Bytes, salt); byte[] hash2 = GetHash(alg, ms, IOPlatformSerialNumber_Bytes, salt, IOMACAddress_Bytes); byte[] hash3 = GetHash(alg, ms, salt, IOPlatformSerialNumber_Bytes, IOMACAddress_Bytes); byte[] LicenseHashs = new byte[60]; Array.Copy(hash1, 00, LicenseHashs, 00, 5); Array.Copy(hash2, 00, LicenseHashs, 05, 5); Array.Copy(hash3, 00, LicenseHashs, 10, 5); Array.Copy(hash1, 05, LicenseHashs, 15, 5); Array.Copy(hash2, 05, LicenseHashs, 20, 5); Array.Copy(hash3, 05, LicenseHashs, 25, 5); Array.Copy(hash1, 10, LicenseHashs, 30, 5); Array.Copy(hash2, 10, LicenseHashs, 35, 5); Array.Copy(hash3, 10, LicenseHashs, 40, 5); Array.Copy(hash1, 15, LicenseHashs, 45, 5); Array.Copy(hash2, 15, LicenseHashs, 50, 5); Array.Copy(hash3, 15, LicenseHashs, 55, 5); byte[] bytesPadding = new byte[400]; for (int index = 0; index < 400; index++) { bytesPadding[index] = 6; } byte[] ret; using (MemoryStream msff = new MemoryStream()) { msff.Write(LicenseHashs, 0, LicenseHashs.Length); msff.Write(bytesPadding, 0, bytesPadding.Length); ret = msff.GetBuffer(); msff.Close(); } File.WriteAllBytes("License.v2", ret); } private static byte[] GetHash(System.Security.Cryptography.HashAlgorithm alg, System.IO.MemoryStream ms, byte[] b1, byte[] b2, byte[] b3) { ms.Position = 0L; ms.SetLength(0L); ms.Write(b1, 0, b1.Length); ms.Write(b2, 0, b2.Length); ms.Write(b3, 0, b3.Length); return alg.ComputeHash(ms.GetBuffer(), 0, (int)ms.Length); }
至於這個 Salt這個陣列，大家動手去找吧，自己動手豐衣足食嘛。。。嘿嘿， 就在mtouch那幾個程式集裡，是常量，我就不提供了，省的影響較大然後出事兒。 真心想用的不差這幾步，看看就走的就別試了，整的亂飛就不好了。
注意，arm-darwin-mono和sgen這兩個原生程式只驗證了授權檔案的前60個位元組和授權檔案從後向前數第128個位元組大於0， 沒有檢查這個授權檔案的數字簽名，所以我們省事了，而mtouch這個驗證了數字簽名，所以呢，咱得處理它，把數字簽名驗證相關咔嚓掉。
下一篇繼續開始測試之旅。
